Configuring the Cisco uMG9850 QAM Module
This document describes how to configure the Cisco uMG9850 QAM Module. The Cisco uMG9850 supports the ITU-T J.83 Annex B standard for the delivery of digital video and audio signals.
This module, designed for Cisco Catalyst 4500 series switches, supports the delivery of digital broadcast and video-on-demand (VoD) services on 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.

Information About the Cisco uMG9850 QAM Module
This section introduces the following concepts that are important in understanding how this product works:
•
Basic Concepts
To configure and use the Cisco uMG9850 series, note the following concepts.
Digital Video
•
•
For digital video services 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. An SPTS contains only one program, and an MPTS contains multiple programs. The Cisco uMG9850 accepts both an SPTS and an MPTS as input, and outputs an MPTS 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.

Cloning is useful for digital broadcast services when the QAM channels are not electrically split for delivery to all service groups. Multicast streams can be cloned to QAM channels on multiple Cisco uMG9850 modules, while unicast streams can be cloned to QAM channels on a single Cisco uMG9850.
Digital Broadcast
Digital broadcast service provides the cable subscriber with a large selection of programs and a high-quality picture. The digital video content is typically received from a satellite broadcasting to a receiver at the headend, from where it is delivered in real time to all subscribers in the cable system. A statistical multiplexer is often used in the headend to combine broadcast programs from multiple sources and generate an MPTS for delivery to the STBs. Program information is also sent to the STB client application, to enable the cable subscriber to browse and select a broadcast program for viewing.
The Cisco uMG9850 supports the following key features for delivering digital broadcast services:
•
•
Video Configuration Modes
It is helpful to understand the various command modes that are used to configure and monitor video services. The following command modes are illustrated in this document:
•
•
Privileged EXEC Mode
Use this configuration 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 configuration 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 shows how to enter global provisioning mode:
Switch# config terminalSwitch(config)#Interface Configuration Mode
There are 12 QAM 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.
The four QAM ports in each modulator circuit package are split into two modulator groups. Thus, each modulator group consists of two QAM ports. Ports 1 and 2 form the first modulator group, ports 3 and 4 form the second modulator group, and so on. There are a total of six modulator groups on the Cisco uMG9850. Both QAM ports in a modulator group share the same video format and interleave settings.
Each QAM port supports two QAM channels, and is addressed as a upconverter group. When both QAM channels are enabled, the output of a QAM port occupies 12 MHz of contiguous bandwidth. Thus, the center frequencies of the two QAM channels in an upconverter group are offset by 6 MHz. Both QAM channels in an upconverter group operate at the same output power.
Video and asynchronous serial interface (ASI) interfaces are addressed, respectively, by the interface qam interface command and the interface asi interface command, as follows:
interface—Slot and port number in slot/port format, where slot is the physical slot in which 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 for a module in slot 6:
Switch(config)# interface qam 6/1Switch(config-if)#The ASI port is always port 15. Address an ASI interface as in the following example for a module in slot 6:
Switch(config)# interface asi 6/15Switch(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 for a module in slot 6:
Switch(config)# interface qam 6/1.1Switch(config-subif)#or
Switch(config)# interface qam 6/1.2Switch(config-subif)#
Tip
UDP Port Mappings: Default, Manual, and Emulation Mode
This section discusses the binary mapping scheme for user datagram protocol (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. An emulation mode feature facilitates the redirection of video streams destined for third-party QAM gateways to a Cisco uMG9850.
The following topics are presented:
•
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 UDP port number to a slot, QAM channel, and program number (from most-significant to least-significant bit, respectively). These default 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. Otherwise, new UDP port mappings must be entered manually. See Manual Mapping.

Example: UDP port number 38946 (0x9822) renders in binary as 1 0011 000001 00010. Following the fixed bit (1), this represents slot 3 (0011), QAM 1 (000001), and program 2 (00010).
Note
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.

Tip
Emulation Mode
The Cisco uMG9850 is able to emulate the UDP port mapping of third-party QAM gateways that accommodate fixed QAM-channel groups of eight or 24 channels each. Up to three eight-channel gateways or one 24-channel gateway can be emulated. The user's mappings are converted to the scheme used by the Cisco uMG9850, and then are reconverted to the user's mapping scheme. IP addresses are assigned automatically. Mapping schemes for some third-party gateways are presented below.
Third-Party Bitwise 8-QAM Mapping Scheme
Table 4 presents an example bitwise mapping scheme for a third-party QAM gateway.

To accommodate the UDP port mapping schemes used by third-party QAM gateways that may already be installed in a VoD network, it is possible to use the video slot emulation-mode command (see video <slot> emulation-mode). For example, where a third-party QAM gateway supports fixed groups of eight QAM channels, the emulation feature accommodates up to three sequential IP addresses—one for each eight-channel group, as shown in Table 5. The user enters only one IP address when the VLAN is configured (see Configuring Gigabit Ethernet Input Ports into a VLAN (Optional)). The other addresses are configured automatically.

Program Data Delivery
The Program Data Delivery (PDD) support provided by the Cisco uMG9850 makes possible the delivery of electronic program guide (EPG) data, other client data, and navigation data to a client application running on the set-top box, enabling the subscriber to browse and select content for viewing. (PDD applies to both broadcast video and video on demand.) Program data can be delivered to the STB either in-band (on a shared QAM channel with digital video services) or out-of-band (on a DOCSIS or QPSK channel). When delivered in-band, the program data is typically delivered as private data in a low-bitrate MPEG program with multiple PIDs. Most cable systems deliver such data through one or more in-band carousels to which the client tunes at startup, as well as during program navigation, as needed.
Program-related information is streamed from a server, and can be delivered to subscribers in-band through the Cisco uMG9850. The data are encapsulated as SPTS MPEG-2 streams delivered by means of UDP/IP, as regular sessions are. Program data can be unicast or multicast from the server to the Cisco uMG9850.
To maximize the efficiency of the IP network, a single copy of a program data stream is sent to a Cisco uMG9850 QAM channel, where the stream can be cloned to one, several, or all QAM channels. Also, the program data stream may contain program clock references (PCRs), or may be a pure data stream without timing information. To support PDD and similar functionality, the Cisco uMG9850 remaps the PID, either by using the default map or a user-specified configuration.
PDD functionality on the Cisco uMG9850 supports the following:

How to Configure the Cisco uMG9850 QAM Module
This section presents a variety of tasks for configuring the Cisco uMG9850. Table 6 lists these tasks by category. A variety of configurations are possible, depending upon the network design. Most likely, video input is on one switch, and the Cisco uMG9850 modules 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.

Determining the Location of a Cisco uMG9850 in the Switch
To provision one or more Cisco uMG9850 modules, you need to know where they reside in the Cisco Catalyst switch. Table 7 shows where the supervisor engines (SEs) and Cisco uMG9850 modules reside in the Cisco Catalyst switch models that support the Cisco uMG9850.
If you do not know where the Cisco uMG9850 modules reside, do the following to determine their locations in the switch.

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.
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 12 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.
Do the following to set the frequency and output power of both QAM channels on a port in a Cisco uMG9850.

The default format is 256.
TipNote
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 QAM channel sets the interleave level and mode for that modulator group. (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 QAM channels in the modulator group.
To set the FEC interleave level and mode for all four QAM channels in the modulator group, perform the following procedure:

Note
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
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 when 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 the video slot timeout command to address an entire module in a given slot, and the video timeout command to address the entire switch. The options and parameters are the same in both cases.
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 video slot timeout session-close command or the video timeout session-close command. 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 the video slot timeout signal-loss command or the video timeout signal-loss command. The session still exists and is listed following a show command. If packets start arriving before the timer set by the video slot timeout session-close command or the video timeout session-close command counts down, the session becomes active. The range is 200 to 10000 milliseconds. The default is 5000 milliseconds.
The value for the video slot timeout signal-loss command or the video timeout signal-loss command should always be larger than the value configured for jitter.

Setting Up 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
The range of the PAT and PMT intervals is 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 channel 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:

Command History
Examples
The following example shows how to clear video statistics on a Cisco uMG9850 in slot 6:
Switch# clear video 6 statisticsSwitch#Related Commands
Various
See show.
interface asi
You can route one of the 24 transport streams (QAM channels) to the asynchronous serial interface (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, 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 the interface asi command in global configuration mode.
interface asi slot/15
Syntax Description
interface
Enables interface configuration mode.
asi
Selects the ASI output port.
slot
Physical slot number for the Cisco uMG9850. For valid slot ranges, see Table 7.
15
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

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 a selected Cisco uMG9850 to ignore conflicting frequencies from being configured, use the video slot frequency allow-any command in global configuration mode. To configure the 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
Slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 7.
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.
Caution
Command Modes

Command History
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 through +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 allow-any option is required to complete this command. There are no other options. Use the interface qam interface.qam frequency command 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:

To configure jitter levels for a selected Cisco uMG9850, use the video slot jitter 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
Slot in which the Cisco uMG9850 resides in the switch. For valid slot ranges, see Table 7.
jitter
Configures the size of the dejitter buffer for all the UDP sessions on the selected Cisco uMG9850.
level
Size of dejitter buffer in milliseconds. Range is 0 to 300.
Defaults
See Usage Guidelines, below.
Command Modes
Global configuration
Command History
Usage Guidelines
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 100 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 video slot udp UDP-port-number jitter command; see video <slot> udp <UDP-port-number> jitter), their current jitter value is maintained.
Tip
The value set by the video slot timeout signal-loss command or the video timeout signal-loss command 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:

Usage Guidelines
The vlan argument is not used with the no form of the command.
With Cisco IOS Release 12.2(20)EU, each Cisco uMG9850 module no longer functions as an IP host. Now the supervisor engine (SE) in the Cisco Catalyst 4500 series switch plays that role, allowing for the aggregation of video traffic.
This command sets up the routing of UDP/IP (video) packets to the Cisco uMG9850. Acting as the IP host, the SE generally receives video traffic on the IP address configured on a VLAN. When the IP address of the selected VLAN is configured as the destination IP address of the video packets, any video packet destined to this IP address—and whose destination port matches the UDP range specified for video by this command—is routed to the selected Cisco uMG9850.
Note
This command is also used in emulation mode. See Setting Emulation Modes for UDP Port Mapping (Optional).

Video route: Video emulation is on, cannot change video route UDP range in slot <slot> to exclude the UDP port range x to y.The range specified by this command is loosely coupled with the user-defined session mapping set by the video sessions command (see video sessions). When the user enters a configuration for user-defined sessions, the selectable range is bound by the range defined by the video slot route vlan command. If, at a later time, the range defined by the command is changed, the user is warned if an already-defined session that is currently active would be made inactive because of this change.
For example, if there is an active session on UDP port 49152 and the user enters
video 3 route vlan 20 udp 50000 65535the following message appears:
Video route: There exists active session(s) in slot 3 outside of udp ports 50000 to 65535, which will become inactive.However, the command itself does not trigger the removal of the already-defined session.
Examples
The following example shows how to assign video traffic on a Cisco uMG9850 in slot 3 to VLAN 20, with explicit packet routing.
Switch(config)# video 3 route vlan 20 udp 49152 65535

Command Modes
Global configuration
Command History
Usage Guidelines
The syntax of this command is similar to that for the video timeout command (see video timeout), except that this command addresses a single Cisco uMG9850 module. You must configure each parameter on a separate command line.
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 video slot timeout session-close command or the video timeout session-close command. 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 the video slot timeout signal-loss command or the video timeout signal-loss command. The session still exists and is listed following a show command. If packets start arriving before the timer set by the video slot timeout session-close command or the video timeout session-close command counts down, the session becomes active. The range is 200 to 10000 milliseconds. The default is 5000 milliseconds.
The value for the video slot timeout signal-loss command or the video timeout signal-loss command should always be larger than the value configured for jitter.
Examples
The following example shows how to set the session-close option to 25 and the signal-loss option to 500 on a Cisco uMG9850 in slot 6:

Syntax Description
frequency
Sets the frequency on both channels on a QAM port.
frequency
Channel 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 7.
Defaults
The default center frequency, in MHz, for each port is determined by the following formula:
100 + (port_ID * 12)
where port_ID is an integer from 0 to 11
Command Modes
Subinterface configuration (QAM interface only). See Subinterface Configuration Mode.
Command History
Usage Guidelines
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 12 MHz. Consequently, if slot/port.1 is set to frequency f1, then slot/port.2 is set to frequency f1 + 6 MHz. Similarly, if slot/port.2 is set to frequency f2, then slot/port.1 is set to frequency f2 - 6 MHz.
Tip
Examples
The following example shows how to set the first QAM channel on port 1 of a Cisco uMG9850 in slot 4 to an upconverter frequency of 850 MHz. This automatically configures the frequency for the second QAM channel on port 1 to 856 MHz.

Values for level are as follows:
•
•
mode
Configures the FEC interleave mode for the QAM channel.
The mode option can be used only when the interleave level is 2 (default).
mode
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 channel for the "I" and "J" interleave values as shown in Table 13.
Defaults
The default interleave level is 2. The default mode is 6.
Note
Command Modes
Subinterface configuration (QAM interface only). See Subinterface Configuration Mode.
Command History
Usage Guidelines
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.
The video interleave command configures the operation of the FEC interleave on the QAM channels. If the interleave level and mode values are set on one QAM channel, the same values are applied to all four QAM channels in a modulator group. See Video Configuration Modes.
When operating with level 2 interleave, you can choose the specific interleave parameters by selecting one of the modes shown in Table 13:

video timeout
You can configure when a video session times out when packets are not received after a certain interval. The video timeout command applies to all the Cisco uMG9850 modules in a switch. To address a single module, use the video slot timeout command (see video <slot> timeout).
To configure timeout parameters on all Cisco uMG9850 modules in a switch, use the video timeout command in global configuration mode. To revert to default values, use the no forms of this command.
video timeout {session-close minutes | signal-loss milliseconds}
no video timeout session-close
no video timeout signal-loss
Syntax Description
Defaults
See Usage Guidelines, below.
Command Modes
Global configuration
Command History
Usage Guidelines
The syntax of this command is similar to that for the video slot timeout command (see video <slot> timeout), except that the video timeout command addresses all the Cisco uMG9850 modules in a switch. You must configure each parameter on a separate command line.
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 video slot timeout session-close command or the video timeout session-close command. 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 the video slot timeout signal-loss command or the video timeout signal-loss command. The session still exists, and is listed following a show command. If packets start arriving before the timer set by the video slot timeout session-close command or the video timeout session-close command counts down, the session becomes active. The range is 200 to 10000 milliseconds. The default is 5000 milliseconds.
The value for the video slot timeout signal-loss command or the video timeout signal-loss command should always be larger than the value configured for jitter.
Examples
The following example shows how to set the session-close option to 25 and the signal-loss option to 500 on all the Cisco uMG9850 modules in a switch:
Switch(config)# video timeout session-close 25Switch(config)# video timeout signal-loss 500See also Statically Setting Session Timeouts.
Related Commands

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 the video tsid command in subinterface configuration mode:
video tsid tsid
Syntax Description
tsid
Configures the transport stream ID.
tsid
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
Usage Guidelines
Caution
See also Setting TSID and NIT-PID Values.
Examples
The following example shows how to specify a transport stream ID of 1001 for QAM channel 2 in port 2 of a Cisco uMG9850 in slot 5:
Switch# configure terminalSwitch(config)# interface qam 5/2.2Switch(config-subif)# video tsid 1001Related Commands
See video nitpid.
Various
See commands indicated as "PSI commands" in Notes column of Table 11.
video udp
Each QAM channel has a default UDP port mapping. For example, a video stream with a destination UDP of 0xd821 is sent to slot 3, QAM port 1 as output program 1. However, for a given UDP session, you can remap (1) input packet IDs (PIDs) and (2) output program numbers to output PIDs on a QAM channel.
To do either of the above, use the video udp 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, Manual, and Emulation Mode.

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 the video utilization-threshold 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
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
Usage Guidelines
If the percentage of QAM bandwidth being used is below the value for the low option, then the QAM channel is being underutilized. If the percentage of QAM bandwidth being used is above the value for the high option, 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 terminalSwitch(config)# interface qam 5/2.1Switch(config-subif)# video utilization-threshold low 10The following example shows how to set a high utilization threshold of 80 percent on interface 5/2.1:
