Configuring the Cisco uMG9850 QAM Module

This document describes how to configure the Cisco uMG9850 QAM Module. This module, designed for the Cisco Catalyst 4500 series switches, provides Video-on-Demand (VoD) services for a hybrid fiber coax (HFC) cable network. It accepts Moving Pictures Expert Group-2 (MPEG-2) digital video from an IP network, and outputs the video as a quadrature amplitude modulated (QAM) RF stream that can be received by digital set-top boxes (STBs) over the cable network.

If you are inserting more than one module, you must wait at least 15 seconds before inserting the next. Otherwise, an assertion error is raised and you must reboot the switch.

Information About the Cisco uMG9850 QAM Module

This section introduces the following concepts that are important in understanding how this product works:

• Basic Concepts

• Video Configuration Modes

• UDP Port Mappings: Default and Manual

Basic Concepts

To configure and use the Cisco uMG9850, note the following digital video concepts:

•Stream—A stream is the output from an MPEG audio or video encoder. The output of a single encoder is an elementary stream (ES). One video stream and one or more audio streams can be combined by means of a shared clock reference into a program, which is the basic unit of a digital video service.

For VoD service on a cable network, video and audio streams are transmitted in a transport stream, which uses fixed-size packets for digital transmission. One or more programs can be combined in a transport stream. A single program transport stream (SPTS) contains only one program, and is output by a VoD server for transmission to the Cisco uMG9850. A multiple program transport stream (MPTS) contains multiple programs, and is output by the Cisco uMG9850 for transmission to an STB. A program clock reference (PCR) is included for each program in the transport stream. Transport streams also contain information for the STB to locate a selected program.

•Session—A session is a stream of video programming being received over an IP network. A session is identified by its UDP port number.

•Program—A program is the audio and video content being delivered to customers.

•Packet identifier—Each elementary stream in a program is identified by a unique packet identifier (PID). In an MPTS, the PID of each elementary stream must be unique, in order for the STB to locate a selected program. The Cisco uMG9850 may change the PID of one or more elementary streams, to ensure the uniqueness of PIDs in an MPTS.

Note PIDs can range from 0 to 8191, but PIDs 0 and 1 are preassigned, and PIDs 2 through 15 are reserved for system use.

•Program specific information—Each transport stream includes a program association table (PAT) that lists every program in the stream. Each program's entry in the PAT points to a program map table (PMT), which lists the PID for each elementary stream that makes up each program in the stream.

•UDP port map—A UDP port map describes the relationship between (1) the UDP port number of a session, and (2) the QAM channel and program number to be assigned to that session. The Cisco uMG9850 uses the UDP port map to route each incoming program to the correct QAM channel. The Cisco uMG9850 also includes a default port map, which may be overwritten with a user-defined UDP port map. The VoD server and the Cisco uMG9850 must be configured with the same UDP port map.

Video Configuration Modes

It is helpful to understand the various command modes that are used to configure and monitor video services. There are four basic command modes:

• Privileged EXEC Mode

• Global Configuration Mode

• Interface Configuration Mode

• Subinterface Configuration Mode

Privileged EXEC Mode

Use this provisioning mode to execute show and debug commands that are specific to video, as well as to other functions on the switch. The following prompt illustrates privileged EXEC mode:

Switch#
Global Configuration Mode

Use this provisioning mode to enter interface and subinterface provisioning modes (through the configure terminal command), to execute commands that support video on the entire switch. The following prompt shows how to enter global provisioning mode:

Switch# config terminal
Switch(config)#
Interface Configuration Mode

There are 12 RF ports or interfaces (F-connectors) on the Cisco uMG9850, in three RF modulator circuit packages with four F-connectors each. Each package performs QAM modulation and RF upconversion.

Pairs of ports are supported by a separate RF upconverter group (or circuit block). Each port is addressed as a QAM provisioning group, with two QAM channels (6 MHz apart) per carrier frequency. Consequently, there are four QAM channels per RF upconverter group, addressed in configuration as slot/1.1, slot/1.2, slot/2.1, and slot/2.2.

Video and asynchronous serial interface (ASI) interfaces are addressed as interface qam interface and interface asi interface, respectively, as follows:

interface—Slot and port number in slot/port format, where slot is the physical slot where the Cisco uMG9850 module resides in the switch, and port is the port on the module. The valid range for slot varies with the type of switch (see Determining the Location of a Cisco uMG9850 in the Switch). The valid range for a video (QAM) port is 1 to 12, with no default.

Address a video interface as in the following example:

Switch(config)# interface qam 6/1
Switch(config-if)#

The ASI port is always port 15. Address an ASI interface as in the following example:

Switch(config)# interface asi 6/15
Switch(config-if)#

Subinterface Configuration Mode

QAM channels are addressed as interface.qam, where interface is slot/port (discussed above), and qam is the QAM channel of interest. The options for qam are 1 or 2, with no default.

Address a QAM channel as in the following examples:

Switch(config)# interface qam 6/1.1
Switch(config-subif)#

or

Switch(config)# interface qam 6/1.2
Switch(config-subif)#

Tip For convenience in entering QAM channel provisioning mode, simply address slot/port.1

UDP Port Mappings: Default and Manual

This section discusses the binary mapping scheme for UDP port numbers (also referred to as session numbers) as used by the Cisco uMG9850 for default mappings, as well as issues related to remapping UDP ports manually when default configurations are not used.

Default Cisco uMG9850 Binary Mapping Scheme for UDP Port Numbers

Table 1 illustrates the default binary mapping scheme used by the Cisco uMG9850 to map a user datagran protocol (UDP) port number to a slot, QAM channel, and program number (from most significant to least significant bit, respectively). These mappings are used for preconfigured UDP port mappings.

Note Normally, UDP port mappings are preconfigured in a file that resides on the VoD server, and must conform to the mapping scheme in Table 1 for nondefault operation. Otherwise, new UDP port mappings must be entered manually. See Manual Mapping.

•There are 16 bits in the UDP port number, from bit 15 through bit 0.

•Bits 15 and 14 are set to 1, complying with requirements for private IP ports.

Note The lowest possible number, 49152 (0xc000, 11000000 00000000), is the lowest number that conforms with the Industry Standard Architecture (ISA) bus standard.

•Bits 13 through 11 define the slot number. The range is 3 to 9.

•Bits 10 through 5 define the QAM number. The range is 1 to 24.

•Bits 4 through 0 define the program (or session) number. The range is 1 to 25.

Example: UDP port number 55330 (0xd822) renders in binary as 11 011 000001 00010. Following the two fixed bits (11), this represents slot 3 (011), QAM 1 (000001), and program 2 (00010).

Note A Cisco uMG9850 can accept a maximum of 600 maps: 24 QAM channels times 25 programs.

Table 2 shows the default mapping of QAM subinterfaces and channels to UDP ports.

Manual Mapping

To create a nondefault mapping manually, use a number starting with decimal 49152 (or hexadecimal 0xc000) to configure a UDP port mapping for one session or a range of sessions at a time. (Numbers can be entered in either format. The system automatically identifies a hexadecimal input by its "0x" prefix). Table 3 shows nondefault UDP port ranges in decimal and hexadecimal formats.

How to Configure the Cisco uMG9850 QAM Module

This section presents a variety of tasks for configuring the Cisco uMG9850. Table 4 lists these tasks by category: switch-level, module-level, and monitoring and troubleshooting:

A variety of configurations are possible, depending upon the network design. Most likely, video input will be on one switch, and the Cisco uMG9850 modules, with unique IP addresses, reside on one or more switches in different subnets. A video stream may or may not use the same VLAN as the modules, and can enter the switch through any Gigabit Ethernet (GE) port that is available.

Tip You can do this in either user mode (illustrated below) or privileged EXEC mode.

Prerequisites

None

Restrictions

You cannot configure a Cisco uMG9850 unless it is physically installed.

You must wait at least 15 seconds after removing a module before you reinsert it. If you are removing more than one module, you must wait at least 15 seconds before removing the next. If you are inserting more than one module, you must wait at least 15 seconds before inserting the next. Otherwise, an assertion error is raised and you must reboot the switch.

Note Module names may vary, but the "Card Type" or "Model" is identified by "QAM." This example shows a single Cisco uMG9850 module, in slot 6.

What to Do Next

Proceed to Configuring Gigabit Ethernet Input Ports into a VLAN.

Configuring Gigabit Ethernet Input Ports into a VLAN

Video streams on inbound GE interfaces are included in single VLANs to use network addresses more efficiently. The IP addresses and subnet masks configured for each VLAN interface populate the IP switching table on the switch with the forwarding information needed to forward the video packets to their destination. The number and use of VLANs varies according to the programming and management needs of the system operator.

Do the following to create a VLAN interface, assign an IP address to the incoming (video source) interface, and assign input GE ports to the VLAN.

Note It is the responsibility of the multiple systems operator (MSO) to plan subnets and VLANS and assign addresses carefully.

Prerequisites

For the last step of this procedure, at least one Cisco uMG9850 module must be in the appropriate slot in the switch. See Table 5.

Example:

Switch> enable

Enables privileged EXEC mode.

•Enter your password when prompted.

Step 2

configure terminal
Example:

Switch# configure terminal

Enables global configuration mode.

Step 3

vlan vlan-id
Example:

Switch(config-vlan)# vlan 20

(Optional) Enters VLAN configuration mode and creates a Layer 3 switch virtual interface (SVI) for video service if one has not been created yet. Range is 1 to 4096.

If a VLAN for video service has been created and made active, proceed to Step 6.

Step 4

state active
Example:

Switch(config-vlan)# state active

Makes the VLAN active.

Tip To confirm which VLANs are active or suspended, use the show vlan command and note the Status column.

Step 5

exit
Example:

Switch(config-vlan)# exit

Exits VLAN configuration mode.

Step 6

interface vlan vlan-id
Example:

Switch(config)# interface vlan 20

Enters interface configuration mode for the VLAN created in Step 3.

Step 7

ip address ip-address mask
Example:

Switch(config-if)# ip address 192.168.20.4 255.255.255.0

Assigns an IP interface and subnet mask to the VLAN.

Step 8

no shut
Example:

Switch(config-if)# no shut

Enables the VLAN interface.

Step 9

interface gigabitethernet slot/port

Example:

Switch(config-if)# interface gigabitethernet 6/10

Assigns a GE interface to be included in the VLAN. (See Interface Configuration Mode.) This is the interface of an incoming video stream.

Tip If you are unsure of the location of modules you want to configure, see Determining the Location of a Cisco uMG9850 in the Switch.

Step 10

video slot route vlan vlan-number ip-address ip-address

Example:

Switch(config)# video 6 route vlan 20 ip-address 192.168.20.6

Switches video packets from the input GE port to the output GE port. A backplane port provides communication between the supervisor engine and the Cisco uMG9850. This command assigns an IP address to that port. This IP address should be in the same subnet as the IP address assigned in Step 6.

Note For the syntax of this command, see video <slot> route vlan.

The VoD server must be configured to deliver a video stream to the destination IP address configured here.

Note At least one Cisco uMG9850 module must be present in the switch chassis. Table 5 shows where the Cisco uMG9850 modules can reside in the supporting Cisco Catalyst switch models.

Step 11

Repeat Step 3 through Step 10 for additional VLAN and Gigabit Ethernet interfaces, as required.

What to Do Next

Proceed to Setting the Frequency and Output Power of the QAM Module Channels.

Setting the Frequency and Output Power of the QAM Module Channels

Each F-connector (QAM port) provides two QAM channels, and the output power and frequency are configured for both channels simultaneously. Setting frequency and power for one QAM channel automatically sets the appropriate values for the other channel in the same interface.

Do the following to set the frequency and output power of the channels on a port in a QAM module.

Note For background, see Interface Configuration Mode.

QAM channels are provisioned in subinterface mode (see Subinterface Configuration Mode), which provides logical access to the subinterface command set for a given slot and port. Generally speaking, consider the provisioning of such basic functions as frequency and power, modulation format (see Setting the Modulation Format), and forward error correction (FEC) interleave level and mode (see Configuring the FEC Interleave Level and Mode) as taking place on both slot/port QAM channels simultaneously and automatically.

Setting the power for one channel automatically sets the same power level on both channels.

Configuring the frequency for one QAM channel automatically configures the correct frequency for the other QAM channel in its upconverter group. The frequency bandwidth of each QAM upconverter block is 6 MHz. Consequently, if slot/port.1 is set to frequency f1, then slot/port.2 is automatically set to frequency f1 + 6 MHz. Similarly, if slot/port.2 is set to frequency f2, then slot/port.1 is automatically set to frequency f2 - 6 MHz.

Example:

Switch(config)# interface qam 6/1.1
Switch(config-subif)#

Enables subinterface configuration mode. See Subinterface Configuration Mode.

Note For the syntax of this command, see interface qam.

Step 4

video frequency frequency
Example:

Switch(config-subif)# video freq 800

The frequency range for QAM slot/port.1 is 50 through 854 MHz, and for QAM slot/port.2 is 56 to 860 MHz.

Note For the syntax of this command, see video frequency.

Step 5

video power power

Example:

Switch(config-subif)# video power 50

When both QAM channels in an RF port are enabled, the power range is from 43 through 58 dBmV. If only one QAM channel is enabled, the range is 42 to 53 dBmV.

Note If both QAM channels are up, RF port power is configured to power + 3 dBmV. If only one channel is up, RF port power is configured to power. If no channel is up, RF port power is not configured.

Frequency and power must be entered on separate command lines.

Note For the syntax of this command, see video power.

Step 6

Monitor video frequency and power.

We recommend that you use appropriate test equipment to monitor video frequency and power before proceeding.

Note For the syntax of this command, see interface qam.

Step 4

video format format

Example:

Switch(config-subif)# video format 64

Sets the modulation format for all four channels in a QAM modulator group—that is, QAM channels 5/1.1, 5/1.2, through 5/2.1, 5/2.2, where

•format = QAM modulation format (256)

The default format is 256.

Tip If the FEC interleave level is set to 1, the option "256" (256QAM) is not available and does not appear. See Configuring the FEC Interleave Level and Mode.

Note For the syntax of this command, see video format.

Configuring the FEC Interleave Level and Mode

Forward error correction (FEC) reduces bit error rate (BER) in data transmission by correcting recovered bit errors in the demodulator. Interleaving is a technique that reorders (in time) individual code-word bits with other code-word bits to spread error bursts over many different code words. The technique used is compliant with ITU J.83, Annex B.

Setting the interleave level and mode on any of the 12 QAM interfaces (ports) sets the QAM symbol rate on that port only. (For background, see Interface Configuration Mode.) If the interleave level and mode is set on one QAM channel, the same value is applied to all four slot/port channels in a modulator group.

To set the FEC interleave level and mode for all four channels in a QAM modulator group, perform the following procedure:

Caution The default settings should be satisfactory. Realize that varying the settings can result in an increase in packet latency. Always monitor new settings to ensure that resulting BERs are acceptable.

Step 4

video interleave level level

Example:

Switch(config-subif)# video interleave level 2

Sets the FEC interleave level, which can be 1 or 2. The default is 2.

Tip If the FEC interleave level is set to 1, the option "256" (256QAM) is not available and will not appear. See Setting the Modulation Format.

Note For the syntax of this command, see video interleave.

Step 5

video interleave mode mode

Example:

Switch(config-subif)# video interleave mode 2

Sets the FEC interleave mode, which can be any value from 1 to 14, except 11 and 13. The default is 6.

Note The mode option can be used only when the interleave level is 2 (default).

Each mode determines a set of I and J values as defined in ITU J.83, Annex B. (Level and mode must be set on separate command lines.)

Note For the syntax of this command, see video interleave.

Statically Setting Session Timeouts

You can statically set a session timeout for the entire Cisco uMG9850 module, or for the entire switch, to determine when the session is closed once packets no longer come into the session. You can also set the time, following the absence of packets, at which a loss of signal is reported. Use video slot timeout to address an entire module in a given slot, and video timeout to address the entire switch. The options and parameters are the same in both cases.

Note When a session is closed, this means that the Cisco uMG9850 has not received any video packets for the given session's UDP port for the period determined by video slot timeout session-close or video timeout session-close. The session no longer exists, and is not listed following a show command. The range is from 1 to 1440 minutes. The default is 10 minutes.

When a session is inactive, this means that the Cisco uMG9850 has not received any video packets for the given session's UDP port for the period determined by video slot timeout signal-loss or video timeout signal-loss. The session still exists, and is listed following a show command. If packets start arriving before the timer set by video slot timeout session-close or video timeout session-close counts down, the session becomes active. The range is from 200 to 10000 milliseconds. The default is 5000 milliseconds.

The value for video slot timeout signal-loss or video timeout signal-loss should always be larger than the value configured for jitter.

Note For the syntax of this command, see video timeout.

Statically Routing a Range of Program Sessions to a QAM Channel

The UDP port number of each program session allows each session to be routed to a designated QAM channel by default. You can overwrite the default routing (which is signaled by the port number) and route a range of program sessions to a QAM channel

Note You can also use this command to route a range of program sessions to the ASI port (port 15) for monitoring. See Configuring the ASI Port for QAM Channel Routing (Optional).

Remaps a UDP port to an output program number on a QAM channel, where UDP-port-number is a UDP port number (see UDP Port Mappings: Default and Manual), and out-program-number ranges from 1 to 255.

Note For the syntax of this command, see video udp.

Configuring Maximum Jitter for a Session

You can set the maximum allowable network jitter (packet latency variation) for a specified UDP port session. This global video setting affects the overall packet latency (at the buffer level) within an entire Cisco uMG9850.

Note The jitter option sets the size of a dejittering buffer that absorbs the input jitter. This buffer introduces system delay (the time for a packet to enter and leave the Cisco uMG9850). The greater the value of jitter, the greater the delay introduced to the output stream.You can change the size of the dejitter buffer at either the slot or the session level. (The default level is the default level for the switch, 300 milliseconds.) Changing it at the slot level changes the default value for jitter. Consequently, for all sessions having the default value for jitter, the jitter value is changed to the new value. For sessions that have nondefault jitter values (as configured by the command video udp), their current jitter value is maintained.

Tip When setting the jitter value (the size of the dejitter buffer), take into consideration the network jitter (the inherent jitter introduced at the input of the Cisco uMG9850), and allow for clock tracking. Leave approximately 50 milliseconds for clock tracking. For example, if peak-to-peak network jitter is 100 milliseconds, set the jitter value to 150 milliseconds.

The value for video slot timeout signal-loss or video timeout signal-loss should always be larger than the value configured for jitter.

Note For the syntax of this command, see video <slot> udp <UDP-port-number> jitter. Jitter can also be configured at the slot level (see video <slot> jitter).

Statically Filtering PIDs

If necessary, you can set up a filter that causes a packet with a given packet identifier (PID) to be dropped for a given UDP session on a selected Cisco uMG9850. If the session does not contain packets with that PID, the filter is ignored.

Remaps an input PID to an output PID on a QAM channel, where UDP-port-number is a UDP port number (see UDP Port Mappings: Default and Manual), and in-pid and out-pid range from 16 to 8191.

Note For the syntax of this command, see video udp.

Setting Up the PSI Parameters

You can set up various program-specific information (PSI) parameters, either globally (for the entire switch) or on an individual QAM channel.

Note If any sessions are active in the switch, global program association table (PAT) and program map table (PMT) commands are rejected. If no sessions are active, the PAT and PMT rates on each QAM port are checked.

The range is from 50 to 450 milliseconds. The default rate is the default rate for the switch, 100 milliseconds. If the QAM rates are different from the original switch rate, they are left unchanged. If they are the same as the original switch rate, the rate is changed on both the QAM port and the switch.

Changing the default rates in global configuration mode changes the rates for the entire switch. Changing the default rates in subinterface configuration mode changes the rates for the selected QAM channel only.

This section presents the following procedures:

• Setting PMT and PAT Intervals for the Switch

• Setting PMT and PAT Intervals on a QAM Channel

• Setting TSID and NIT-PID Values

Note For the syntax of this command, see video interval pmt.

Setting TSID and NIT-PID Values

At each hub, each QAM channel must have a unique transport stream ID (TSID). The software checks for and guarantees the uniqueness of a TSID within a chassis only.

Caution It is the responsibility of the operator to avoid TSID conflicts among switches. To see all the TSIDs within a switch, use the command show video <slot>, and address each Cisco uMG9850 in the switch.

The PID for the network information table, or NIT-PID, can be configured from the QAM interface. If the NIT-PID is already used as a video, audio, or data PID, the configuration is rejected.

For the transport stream that is to be transmitted over a QAM channel, you must configure the TSID and NIT-PID (network information table packet ID) values for that channel.

To set TSID and NIT-PID values:

Configuring the ASI Port for QAM Channel Routing (Optional)

You can route the input of a single QAM channel to the asynchronous serial interface (ASI) port to monitor the channel. This section discusses how to configure the ASI port, and route the input of a QAM channel to the ASI port.

Note Routing the input of a QAM channel to the ASI port does not disrupt the RF output.

This section presents the following procedures:

• Setting the Byte-Gap Value (S-rate) of the ASI Port

• Routing the Output of a QAM Channel to the ASI port

Setting the Byte-Gap Value (S-rate) of the ASI Port

You can change the gap spacing of the data bytes in the output of the ASI port. The S-rate is the spacing of data bytes (the number of ASI transport null bytes between the data bytes) within the output transport stream. If there is not a sufficient number of data bytes in the stream, padding the stream with null bytes maintains the signal voltage and integrity.

Configuration Examples for the Cisco uMG9850 QAM Module

This section presents basic configurations on both the headend switch, which accepts video streams from a VoD server, and on the distribution hub (Dhub) switch, which delivers selected streams to set-top boxes on customer premises:

• Headend Switch Configuration: Example

• Dhub Switch Configuration: Example

Figure 1 illustrates Cisco uMG9850 modules in a basic video distribution architecture, with a headend and a Dhub switch connected through a single EtherChannel.

Note For a thorough discussion of video distribution architectures and related issues, refer to Cisco Gigabit-Ethernet Optimized VoD Solution Design and Implementation Guide, at the following URL:

http://www.cisco.com/univercd/cc/td/doc/solution/vodsols/geopt1/voddig/index.htm

Figure 1 Cisco uMG9850 Modules in a Basic Video Distribution Architecture

•Two types of VoD server provide the video streams to the headend switch, a Cisco Catalyst 4507.

•The headend switch, in turn, delivers video traffic through a single EtherChannel to another Cisco Catalyst 4507, in the Dhub.

•The three VLANs are as follows:

–VLAN 10: 192.168.5.254, ingress VoD traffic

–VLAN 20: 192.168.4.254, Cisco uMG9850 in slot 4 of Dhub switch

–VLAN 30: 192.168.111.100, Cisco uMG9850 in slot 5 of Dhub switch

•Video traffic is delivered over two Gigabit Ethernet (GE) interfaces that share VLAN 10.

•The Cisco uMG9850 in slot 4 in the Dhub switch forwards selected video streams (ranging from QAM 4/1.1 through 4/12.2) to set-top boxes.

•The ASI port of the Cisco uMG9850 in slot 4 of the Dhub switch is configured to route the output of QAM channel 4/1.1 to an MPEG analyzer.

Related Commands

Command

Description

Various

See show.

interface asi

You can route one of the 24 transport streams (QAM channels) to the ASI output port. This allows you to route a stream to a decoder, monitor, or MPEG analyzer for troubleshooting. This command is used to enter ASI interface configuration mode, in order to use video route and video byte-gap.

To enter interface configuration mode for an asynchronous serial interface (ASI) output port on the Cisco uMG9850, use this command in global configuration mode.

interface asi slot/15
Syntax Description

interface

Enables interface configuration mode.

asi

Selects the ASI output port.

slot

Specifies the physical slot number for the Cisco uMG9850 QAM Module. For valid slot ranges, see Table 5.

15

Specifies the required physical port. The number of the ASI port on the Cisco uMG9850 is always 15.

Defaults

The number of the ASI port on the Cisco uMG9850 is always 15.

Command Modes

ASI interface configuration. See Interface Configuration Mode.

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

The ASI port is always port 15 on each module. The slot varies. Use no shut to enable the port.

Note Routing the input of a QAM channel to the ASI port does not disrupt the RF output.

Examples

The following example shows how to enter interface configuration mode for the ASI port on the Cisco uMG9850 in slot 4, assign QAM channel 3/7.2 to the ASI interface, and set a byte gap of 1:

Switch# configure terminal
Switch(config)# interface asi 6/15
Switch(config-if)# video route interface qam 6/7.2
Switch(config-if)# video byte-gap 1
Switch(config-if)# no shut

video <slot> frequency allow-any

Frequency conflicts can result in undesirable results, depending on how QAM channels are cabled. This command allows you to configure the software either to allow frequency conflicts or to check for them and block conflicting assignments.

To configure the entire Cisco uMG9850 to ignore conflicting frequencies from being configured, use this command in global configuration mode. To configure the entire Cisco uMG9850 to check for conflicting frequencies, use the no form of this command.

video slot frequency allow-any
no video slot frequency allow-any
Syntax Description

no

Instructs the software to check for frequencies that conflict with frequencies that have already been set.

slot

The slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 5.

frequency

Instructs the software to check for conflicting frequencies. Used with allow-any (see below).

allow-any

Parameter required to complete the command, both with and without the no form.

Defaults

Frequency conflicts are allowed. Note the following Caution:

Caution Because the default allows frequency conflicts, it is the responsibility of the MSO to avoid such conflicts. To instruct the Cisco uMG9850 to check for frequency conflicts, use no video slot frequency allow-any.

Command Modes

Global configuration

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

If instructed to check for conflicts, the software checks whether any QAM channel has already been set to a frequency within the range -6 to +6 MHz of the frequency about to be configured. If the new frequency is within this range, the user is prevented from configuring the conflicting frequency.

The option allow-any is required to complete this command. There are no other options. Use the command interface qam interface.qam frequency to set the frequency on QAM channels.

Examples

The following example shows how to allow any frequency to be set on a Cisco uMG9850 in slot 6:

Switch(config)# video 6 frequency allow-any

The following example shows how to check for conflicting frequencies on a Cisco uMG9850 in slot 6, and prevent conflicting assignments:

Switch(config)# no video 6 frequency allow-any

video <slot> jitter

To configure jitter levels for a Cisco uMG9850 in a given slot, use this command in global configuration mode. To return to default values, use the no form of this command.

video slot jitter level
no video slot jitter
Syntax Description

slot

The slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 5.

jitter

Configures the size of the dejitter buffer for the entire Cisco uMG9850.

level

Size of dejitter buffer in milliseconds. The range is from 0 to 300.

Defaults

See Usage Guidelines, below.

Command Modes

Global configuration

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

Note the following:

Note The jitter option sets the size of a dejittering buffer that absorbs the input jitter. This buffer introduces system delay (the time for a packet to enter and leave the Cisco uMG9850). The greater the value of jitter, the greater the delay introduced to the output stream. You can change the size of the dejitter buffer at either the slot or the session level. (The default level is the default level for the switch, 300 milliseconds.) Changing it at the slot level changes the default value for jitter. Consequently, for all sessions having the default value for jitter, the jitter value is changed to the new value. For sessions that have nondefault jitter values (as configured by the command video udp), their current jitter value is maintained.

Tip When setting the jitter value (the size of the dejitter buffer), take into consideration the network jitter (the inherent jitter introduced at the input of the Cisco uMG9850), and allow for clock tracking. Leave approximately 50 milliseconds for clock tracking. For example, if peak-to-peak network jitter is 100 milliseconds, set the jitter value to 150 milliseconds.

The value for video slot timeout signal-loss or video timeout signal-loss should always be larger than the value configured for jitter.

Examples

The following example shows how to set the jitter level on a Cisco uMG9850 in slot 6 to 150 milliseconds:

Switch(config)# video 6 jitter 150

The following example shows how to return the jitter level for a Cisco uMG9850 in slot 6 to default values:

Switch(config)# no video 6 jitter

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

The syntax of this command is similar to that for the command video timeout, except that this command addresses a single Cisco uMG9850 module. You must configure each parameter on a separate command line.

Note When a session is closed, this means that the Cisco uMG9850 has not received any video packets for the given session's UDP port for the period determined by the commands video slot timeout session-close or video timeout session-close. The session no longer exists, and is not listed following a show command. The range is from 1 to 1440 minutes. The default is 10 minutes.

When a session is inactive, this means that the Cisco uMG9850 has not received any video packets for the given session's UDP port for the period determined by the commands video slot timeout signal-loss or video timeout signal-loss. The session still exists, and is listed following a show command. If packets start arriving before the timer set by the commands video slot timeout session-close or video timeout session-close counts down, the session becomes active. The range is from 200 to 10000 milliseconds. The default is 5000 milliseconds.

The value for the commands video slot timeout signal-loss or video timeout signal-loss should always be larger than the value configured for jitter.

Examples

The following example shows how to set session-close to 25 and signal-loss to 500 on a Cisco uMG9850 in slot 6:

The session no longer exists, and is not listed following a show command. The range is 1 to 1440 minutes. The default is 10 minutes.

When a session is inactive, this means that the Cisco uMG9850 has not received any video packets for the given session's UDP port for the period determined by video slot timeout signal-loss or video timeout signal-loss. The session still exists, and is listed following a show command. If packets start arriving before the timer set by video slot timeout session-close or video timeout session-close counts down, the session becomes active. The range is 200 to 10000 milliseconds. The default is 5000 milliseconds.

The value for video slot timeout signal-loss or video timeout signal-loss should always be larger than the value configured for jitter.

Examples

The following example shows how to set session-close to 25 and signal-loss to 500 on all the Cisco uMG9850 modules in a switch:

Switch(config)# video timeout session-close 25
Switch(config)# video timeout signal-loss 500

video tsid

At each hub, each QAM channel must have a unique transport stream ID (TSID). The software checks for and guarantees the uniqueness of a TSID within a chassis only.

To specify the transport stream ID (TSID) to be used to identify transport stream packets that are sent on a QAM channel, use this command in subinterface configuration mode:

video tsid tsid
Syntax Description

tsid

Configures the transport stream ID.

tsid

Specifies the unique identifier for the transport stream on the output port. Range is 1 to 65535, with no default.

Defaults

By default, nonconflicting TSIDs are assigned to all Cisco uMG9850 modules in a switch. See Usage Guidelines, below.

Command Modes

Subinterface configuration (QAM interface only). See Subinterface Configuration Mode.

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

Note the following Caution:

Caution Although by default nonconflicting TSIDs are assigned to all Cisco uMG9850 modules in a switch, the user can assign conflicting TSIDs within an individual module, resulting in conflicts with other TSIDs in the switch. It is the responsibility of the MSO to avoid TSID conflicts. To see all the TSIDs within a switch, use the command show video <slot>, and address each Cisco uMG9850 in the switch.

Examples

The following example shows how to specify a transport stream ID of 1001 for all packets sent out QAM channel 2 in port 2 of a Cisco uMG9850 in slot 5:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# video tsid 1001

Various

See commands indicated as "PSI commands" in Notes column of Table 9.

video udp

Each QAM channel has a default UDP port mapping. For example, a video stream with a destination UDP of 0xd821 will be sent to slot 3, QAM port 1 as output program 1. However, for a given User Datagram Protocol (UDP) session, you can remap (1) input packet IDs (PIDs) and (2) output program numbers to output PIDs on a QAM channel.

To remap either of the above, use this command in subinterface (QAM channel) configuration mode. To remove the user defined portmapping for a specific port number and program, use the no form of this command.

video udp UDP-port-number {[in in-pid out out-pid] | program prog-number}
no video udp UDP-port-number program prog-number
Syntax Description

udp

Configures UDP parameters

UDP-port-number

UDP port number for the desired incoming session. Range is 49152 to 65535, with no default. See UDP Port Mappings: Default and Manual.

in

Configures the input PID to be filtered out from this session.

in-pid

Range is 16 to 8191, with no default.

out

Statically maps the input PID to the specified output PID, overriding the default output PID that is generated by the video subsystem.

out-pid

Range is 16 to 8191, with no default.

program

Creates a static route that maps an output program number on a UDP port to a QAM channel.

prog-number

The program to be routed. Range is from 1 to 255, with no default.

Defaults

No default behaviors or values

Command Modes

Subinterface (QAM channel) configuration. See Subinterface Configuration Mode.

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

An in-pid can be filtered whether or not an out-pid is specified.

Timesaver To generate a range of 25 UDP portmaps automatically, use the command video sessions.

Examples

The following example shows how to map input PID 16 on UDP session 49152 on interface 5/2.1 to output PID 17:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# video udp 49152 in 16 out 17
Switch(config-subif)#

The following example shows how to route the input stream delivered to UDP port 49152 to QAM channel 5/2.1 as program 1:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# video udp 49152 program 1

The following example shows how to remove the user-defined portmapping UDP port 49152 to QAM channel 5/2.1 as program 1:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# no video udp 49152 program 1

Tip Occasionally, if user-defined port mapping is removed, the default port mapping does not appear following the execution of the command show interface qam <interface.qam> video portmap. To generate the default port mapping, execute no video sessions. See Related Commands, below.

video sessions

Use this command to generate 25 UDP portmap entries automatically. See video sessions.

video utilization-threshold

It is possible that a given QAM channel can be either overwhelmed or underutilized. To monitor and correct for this, you can set either or both minimum and maximum bandwidth-utilization thresholds for video streams over a QAM channel.

To specify the high and low utilization thresholds for video streams, use this command in subinterface (QAM channel) configuration mode. To reset the values to their defaults, use the no form of this command.

video utilization-threshold {[low low-utilization threshold] | [high high-utilization-threshold]}
no video utilization-threshold
Syntax Description

utilization-threshold

Enables the setting of low and high utilization thresholds for video traffic on a QAM channel.

low

Sets the low threshold.

low-utilization-
threshold

Utilization in percent, ranging from 0 through 95. See Defaults, below.

high

Sets the high threshold.

high-utilization-
threshold

Utilization in percent, ranging from 5 through 95. See Defaults, below.

Defaults

The default low utilization threshold is 0 percent. The default high utilization threshold is 75 percent.

Command Modes

Subinterface configuration (QAM interface only). See Subinterface Configuration Mode.

Command History

Release

Modification

12.1(20)EU

This command was introduced.

Usage Guidelines

If the percentage of QAM bandwidth being used is below the value for low, then the QAM channel is being underutilized. If the percentage of QAM bandwidth being used is above the value for high, then the QAM channel is being overutilized.

The high utilization threshold must be greater than the low utilization threshold. You can set either or both thresholds.

Examples

The following example shows how to set a low utilization threshold of 10 percent on interface 5/2.1:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# video utilization-threshold low 10

The following example shows how to set a high utilization threshold of 80 percent on interface 5/2.1:

Switch# configure terminal
Switch(config)# interface qam 5/2.1
Switch(config-subif)# video utilization-threshold high 80

ip-address	Assigns an IP address to a backplane port supporting communications between the supervisor engine and the Cisco uMG9850.

slot	The slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 5.
timeout	Configures the timeout options.
session-close	Configures the time after packet loss when the video session is closed
minutes	Number of minutes, from 1 to 1440.
signal-loss	Configures the time after packet loss when a signal loss is assumed. The session becomes inactive.
milliseconds	Number of milliseconds, from 200 to 10000.

slot	The slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 5.
udp	Configures PID filter and jitter parameters for the entire Cisco uMG9850.
UDP-port-number	UDP port. See UDP Port Mappings: Default and Manual.
filter-pid	Filters out an input elementary video stream based on its input PID.
PID-number	Range is 0 to 8191

byte-gap	Sets the number of null ASI transport bytes to be inserted between data bytes in the output streams.
bytes	Range is 1 to 4, with a default of 2.

64	Configures the port for the 64QAM modulation rate.
256	Configures the port for the 256QAM modulation rate (default).

Command	Description
video frequency	Sets the frequency on a QAM interface. See video frequency.
video interleave	Sets the FEC interleave on a QAM interface. See video interleave.
video power	Sets the power on a QAM interface. See video power.

frequency	Sets the port frequency on both channels on a QAM port.
frequency	Port frequency, in megahertz (MHz). The frequency range for QAM slot/port.1 is 50 to 854 MHz, and for QAM slot/port.2 is 56 to 860 MHz. For valid slot ranges, see Table 5.

Command	Description
video format	Sets the modulation format on a QAM interface. See video format.
video interleave	Sets the FEC interleave on a QAM interface. See video interleave.
video power	Sets the power on a QAM interface. See video power.

interleave	Enables configuration of FEC interleave level and mode.
level	Configures the FEC interleave level for the port.
level	The valid values for level are as follows: •1 = FEC interleave level 1 •2 = FEC interleave level 2 (default)
mode	Configures the interleave mode for the port. The mode option can be used only when the interleave level is 2 (default).
mode	The valid range for mode is any value from 1 to 14, with the exception of 11 and 13. The default is 6. Each mode configures the port for the "I" and "J" interleave values as shown in Table 11.
