Starting and Configuring the Cisco uMG9820

This chapter describes how to start the system and initially configure your Cisco uMG9820. The chapter presents the following major topics:

• Checking Conditions Prior to System Startup

• Starting the System

• Configuration Tasks

In addition, for a sample running configuration file, see the following:

• Sample Configuration

Note The initial configuration of the Cisco uMG9820 is done from a console. Connect a terminal to the Cisco uMG9820's console port using the adapter cable kit provided. See Connecting to the Console Port, page 3-10.

Checking Conditions Prior to System Startup

Ensure the following before you start your Cisco uMG9820:

•The processor card is inserted securely in its slot.

•The primary VoD network feed has been connected to the GIG1 port.

•(Optional) A redundant VoD network feed (if redundancy is required) has been connected to the GIG2 port.

•The SFP modules used in the GIG1 and GIG2 ports are compatible with the physical interface to the VoD network.

•The NMS port is connected to the LAN that accesses the web-based control interface.

•The CAS port is connected to the LAN that supports conditional access.

•A terminal is connected to the Cisco uMG9820's console port, using the adapter cable kit provided. The console port is accessed through a terminal emulation package such as Hyperterminal. Use the setting shown in Connecting to the Console Port, page 3-10.

Starting the System

After installing the Cisco uMG9820 and connecting required cables, start the Cisco uMG9820 as follows:

Step 1 At the back of the Cisco uMG9820, insert one end of the power cord into the AC-input receptacle, then insert the other end into the power outlet.

The green power (POWER) LED on the Cisco uMG9820 comes on.

Step 2 Listen for the fans. You should immediately hear them operating.

Step 3 During the boot process, observe the system LEDs.

The front panel LEDs (PS/FAN, PROC, and QAM 1 through 6) transition from off to yellow, then to green, and then to the functionality as described in Table 1-2. If the processor card is not installed on power-up, all LEDs (except the POWER LED) default to off.

Note If the processor card is removed after power-up, all LEDs maintain their current state, except that the PROC CARD LED goes off.

Step 4 Observe the initialization process. When the system boot is complete (after a few seconds), the processor card begins to initialize the interfaces. During this initialization, the LEDs on each port behave differently (most flash on and off).

The LNK LED on each processor card interface comes on when initialization is completed, and the console screen displays a system banner similar to the following:
Enter <CTRL D> to stop Operating System auto-boot:..... 1

Step 5 If the system completes all the above steps successfully, proceed to Configuration Tasks, for initial software configuration procedures.

Step 6 If the system does not complete each of the steps in the startup procedure, proceed to "Troubleshooting," for troubleshooting recommendations and procedures.

• QAM Ports

• ASI Interface

• Console Port Interface

Syntax Overview

Commands use the following general syntax, where variables are in italics and command names and keywords are in bold:

Hostname(mode)# [no] keyword {keyword1 argument1 | keyword2 argument2 | ...} [keyword1 argument1 | keyword2 argument2 | ...], where Hostname and mode are variables, as follows:

Hostname—Is the user-settable name for the unit. In this document, uMG9820 is used in all examples.

•(mode)#— Describes the current provisioning mode, such as the following:

–uMG9820#—Indicates enable mode

–uMG9820(config)#—Indicates configuration mode

–uMG9820(config-if)#—Interface mode

–uMG9820(config-subif)#—Subinterface mode

•no—Some commands have an option to remove the previous configuration using the no prefix. In most cases this restores default settings.

•keyword— Describes each command, as in the following examples:

–gigabitethernet and fastethernet—Configures the Ethernet ports

–qam—Configures the RF QAM port

–show—Retrieves configuration data and statistics

–video—Defines video-related parameters

Ethernet Interfaces

Ethernet interfaces are addressed as follows:

slot/port

where slot is always zero (0) for Ethernet interface ports. The keywords for Ethernet interface ports are as follows:

•gigabitethernet—Gigabit Ethernet port

•fastethernet—Fast Ethernet

QAM Ports

The QAM ports are addressed by means of subinterface notation, as follows:

slot/port.qam

with the variables defined below:

•slot addresses slots from 1 through 6

•port addresses the output ports 1 or 2, counting from left to right (looking at the rear of the unit)

•qam addresses the QAM channels 1 or 2, within each port

ASI Interface

The ASI output interface is configured by means of the keyword asi.

Note This port is not functional in initial releases of this product. It is intended for future use.

Console Port Interface

The RS-232 console port is configured by means of the terminal command in configuration mode.

Configuring Passwords

This section covers commands for the following operations:

• Enabling and Disabling Passwords for Configuration Mode

• Configuring a Telnet Password

Enabling and Disabling Passwords for Configuration Mode

To specify and enable or disable the configuration mode password:
uMG9820(config)# [no] enable password password

where

password = Text string for the password

Example—Set password for entering terminal configuration mode to "cisco":
uMG9820(config)# enable password cisco
Example—Disable password requirement for entering terminal configuration mode:
uMG9820(config)# no enable password
Configuring a Telnet Password

To specify and enable or reset the system Telnet password:
uMG9820(config)# [no] line vty password password

where

password = Text string for the password

Note The default Telnet password is cisco.

Example—Set the password for entering configuration mode when using Telnet to "cisco":

uMG9820(config)# line vty password cisco

Example—Set the password for entering configuration mode when using Telnet to the default value:

uMG9820(config)# no line vty password

Note There are no other line vty commands for the Cisco uMG9820.

Configuring GE Ports

This section covers commands for the following operations on the ports labeled GIG1 and GIG2:

• Enabling and Disabling a GE Port

• Setting GE Port IP Address and Subnet Mask

• Setting GE Port MAC Address

• Providing Redundancy for Failover

• Retrieving GE Statistics

• Retrieving GE Port Status

Enabling and Disabling a GE Port

To enable and disable a GE port:

uMG9820(config-if)# [no] shut

Example—Enable GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no shut
Example—Switch active GE port from 1 to 2:

Note To enable GE port 2, first disable GE port 1 (GIG1), then enable GE port 2 (GIG2).

uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# shutuMG9820(config-if)# exituMG9820(config)# interface gigabitethernet 0/2uMG9820(config-if)# no shut

Note Only one GE port can be active at a time. If no shut is applied to GE port 1 and GE 2 is active, shut is applied automatically to GE 2. See Providing Redundancy for Failover. However, both GE ports can be inactive at the same time.

Setting GE Port IP Address and Subnet Mask

To set the IP address and subnet mask for a GE port:
uMG9820(config-if)# ip address IP address subnet mask

where

IP address = Text string for standard IP address

subnet mask = Text string for standard subnet mask

Example—Set IP address to 192.168.0.10 and subnet mask to 255.255.255.0 for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# ip address 192.168.0.10 255.255.255.0

Note The IP address and subnet mask applied to one GE port is automatically applied to both GE ports. See Providing Redundancy for Failover.

Setting GE Port MAC Address

To set the IP address for a GE port:
uMG9820(config-if)# mac-address MAC address

where

MAC address = Text string for standard MAC address in H.H.H format

Example—Set the MAC address to 0000.0123.5678 for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# mac-address 0000.0123.5678

Note The MAC address applied to one GE port is automatically applied to both GE ports. See Providing Redundancy for Failover, below.

Providing Redundancy for Failover

Both GE ports share the same IP and MAC addresses. This facilitates failover in scenarios requiring 1+1 redundancy. To provide for failover between a VoD server and the Cisco uMG9820, you need to split the VoD content stream into two identical streams and feed each stream to a GE port.

Retrieving GE Statistics

To display packet and buffer statistics for the specified GE port:
uMG9820# show interface gigabitethernet slot/port

where

slot = 0

port = 1 or 2

Example—Show the SFP module and hardware data for GE port 1:
uMG9820# show interface gigabitethernet 0/1
GigabitEthernet 0/1 is up, line state is cable not installed.Hardware is Gigabit Ethernet Port, address is 0050.c206.e2c3IP address is 192.168.145.93Full-duplex, 1000Mb/s0 packets input, 0 bytesReceived 0 broadcasts (0 multicast)0 runts, 0 giants0 input errors, 0 CRC, 0 overrun0 packets output, 0 bytes0 output errors
Retrieving GE Port Status

To display the status of the specified GE port:

•Link status (up or down)

•Packet and buffer counters
uMG9820# show ip interface [brief] gigabitethernet slot/port

where

brief = Optional keyword to display link status only

slot = 0

port = 1 or 2

Example—Show the status of GE port 1:
uMG9820# show ip interface gigabitethernet 0/1
GigabitEthernet 0/1 is down, line state is no module installed.Inbound access list is not set
Example—Show only the link status of GE port 1:
uMG9820# show ip interface brief gigabitethernet 0/1
Interface IP-address OK Method Status ProtocolGigabitEthernet0/1 192.168.1.34 NO Manual Up Down

To see the status of all Ethernet ports, use the following command:

Example—Show the status of all Ethernet ports:
uMG9820# show ip interface
FastEthernet 0/1 is UpInternet address is 192.168.145.130, subnet mask is 255.255.255.0Broadcast address of 192.168.145.255 is validMTU is 1500 bytes, Metric is 1FastEthernet 0/2 is UpInternet address is 64.13.20.160, subnet mask is 64.13.20.160Broadcast address of 64.13.20.160 is validMTU is 1500 bytes, Metric is 1GigabitEthernet 0/1 is up, line state is cable not installed.Inbound access list is not setGigabitEthernet 0/2 is down, line state is no module installed.Inbound access list is not set

Note To clear counters, use the clear counters command in terminal configuration mode, as follows:

uMG9820(config)# clear counters

Using GE Session Commands

This section covers commands for the following operations:

• Setting the UDP Port Assignment

• Setting Session Timeouts

• Setting Maximum Network Jitter

• Setting PID Remapping

• Binding a UDP Port to a VoD Server

• Retrieving Input Session Data

• Retrieving Input Session PSI Data

Setting the UDP Port Assignment

There are two ways to set the UDP port assignment:

• Default Method

• User-Defined Method

Tip See also the provisioning information provided in Special Issues: UDP.

Default Method

The UDP port is a 16-bit number of the form QQQQQQQQ PPPPPPPP, with a valid range of 0x0100 through 0x18FF, where the bytes are defined as follows:

•Program 0 (0x00) is always reserved for the Network Information Table (NIT), when one is to be used. The NIT is optional.

•QQQQQQQQ = QAM channel (0x01 through 0x18).

•PPPPPPPP = Assigned program number (0x01 through FF).

Note A maximum of 16 programs can be active on any single QAM channel at any time, provided the aggregate bit rate of all the programs does not exceed (1) 38.81070 Mbps for 256QAM, or (2) 26.97035 Mbps for 64QAM. (64QAM is not available in initial releases.)

Table 4-1 shows the mappings between the QAM subinterfaces and channels and the UDP ports. All port ranges for each channel are from 1 through 255 (00000001-11111111). Program 0 is represented by numbers such as 256, 512, 768, ... 6144.

User-Defined Method

You can override the default UDP port mapping for individual QAM channels by specifying the starting UDP port, the increment (sequential or even), and the total number of ports to map. For example, if the starting UDP port is 0x4000, the increment is even, the total number of ports to map is 0x9, and QAM channel 1 is targeted, then UDP ports 0x4000, 0x4002, 0x4004, 0x4006, 0x4008, 0x400A, 0x400C, 0x400E, and 0x4010 are mapped to QAM channel 1.

uMG9820(config-subif)# [no] video udp UDP-port-number {program program-number
[use {even| sequential} count]}

where

UDP-port-number = UDP port number of the desired incoming session to be mapped

If a range is being defined, this number acts as the initial value in the series. Subsequent values are incremented according to either an even or a sequential numbering scheme, as specified by the user.

program-number = Output program number that the sessions are mapped to

If a range is being defined, this number also acts as the initial value in the series. Subsequent values are incremented according to the same numbering sequence as the UDP port number (even or sequential).

use {even | sequential} = Type of sequence to be used for UDP port and program numbering

use even = increment value by two; use sequential = increment value by one

count = Number of UDP ports to be mapped to this QAM channel

Example—Map incoming session on UDP port 5201 to program 10 on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video udp 5201 program 10
Example—Map incoming sessions on UDP ports 8201, 8203, 8205, and 8207 to program numbers 2, 4, 6, and 8, respectively, on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video udp 8201 program 2 use even 4
Example—Remove mapping of UDP ports 8201 to program number 2 on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# no video udp 8201 program 2
Example—Revert all mapping of UDP ports on slot 1, port 1, QAM channel 2 to default mapping behavior:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# no video udp
Special Issues: UDP

Note the following special issues related to UDP:

1. Each MPEG SPTS is encapsulated in UDP datagrams and is assigned a Destination UDP port number by the VoD server.

2. Each UDP datagram can contain a maximum of seven 188-byte MPEG packets. Because only one destination UDP port can be defined for each UDP datagram, all of the MPEG packets contained in a UDP datagram must come from the same program.

3. A maximum of 256 SPTSs, programs, sessions, or UDP port sessions can be sent to the Cisco uMG9820 at a time. The 257th is dropped.

4. The terms "program" and "UDP port session" are used synonymously, because each program (movie) can be uniquely identified by its destination UDP port while it is active. The term "session" is also sometimes used. A UDP port can be mapped to only one QAM channel at any time (For example, if UDP port 5201 is currently mapped to QAM channel 1 and at some point the user maps UDP port 5201 to QAM channel 2, then the mapping between UDP port 5201 and QAM channel 1 is removed automatically.

5. Within the Cisco uMG9820, a user can map any number of UDP port numbers to a QAM channel. Each UDP port mapped to a QAM channel occupies a program space when active. A maximum of 16 programs (or program spaces) can be active on any single QAM channel at any time, provided the aggregate bit rate of all the programs does not exceed 38.81070 Mbps using 256QAM or 26.97035 Mbps using 64QAM (if available). These information rates are dictated by the ITU J.83 Annex B standard.

The implication of this is that QAM channel loading is entirely the responsibility of the end user to manage. Suppose the following:

–A user maps more than 16 UDP ports to a QAM channel.

–The SPTS for each UDP port is a 3.75-Mbps movie when active.

–256QAM is being used.

If an 11th SPTS/UDP port session is requested on that QAM channel, and its addition exceeds the total bandwidth (38.81071 Mbps), then all programs in that channel will be randomly corrupted (their packets dropped) until the bandwidth is reduced by (a) removing a session, or (b) reducing the bandwidth required by one or more sessions.

In summary, the user is responsible for bandwidth management. Although the user can request up to 16 sessions per QAM channel, the total bandwidth for the channel cannot be exceeded. Otherwise, MPEG packets will be randomly dropped from all the sessions on that block. For example, a user can put 16 low-bandwidth (< 2.4 Mbps) sessions on one 256QAM channel, with no problem. However, if the user puts three HDTV (15 Mbps x 3 = 45 Mbps) sessions on that channel all three programs will be randomly corrupted.

6. When default UDP port mapping is used, the range of valid program numbers is restricted to 1 to 255 because only the low-order byte is used to assign the program number. The implication of this is that the user will never see a program number outside the range of 1 to 255 when using default UDP port mapping.

Setting Session Timeouts

To set session timeouts for the GE ports:
uMG9820(config-if)# [no] video timeout {inactive inactive-time | release release-time | queue deallocation-time}

where

inactive-time = Mark sessions as "inactive" if they have not received an IP packet for inactive-time in milliseconds

The default value for inactive-time is the maximum network jitter value (set by user; see Setting Maximum Network Jitter) plus 100 milliseconds.

release-time = Remove system resources and outgoing PSI program references for sessions that have gone to an "inactive" state after release-time in seconds

The default value for release-time is 5 seconds.

deallocation-time = Deallocate system resources for sessions that have gone to an "inactive" state for deallocation-time in seconds

The default value for deallocation-time is 5 minutes.

Example—Set inactive time to 500 milliseconds for all sessions on GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# video timeout inactive 500
Example—Set release time to 10 seconds for all sessions on GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# video timeout release 10
Example—Set deallocation time for the queue to 4 minutes for all sessions on GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# video timeout queue 240
Example—Set inactive time to default value for all sessions on GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no video timeout inactive
Example—Set release time to default value for all sessions on GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no video timeout release
Setting Maximum Network Jitter

To set the maximum allowable network jitter (packet latency) for the specified UDP port session:

Note This setting is not supported in initial releases. It affects the session's overall latency within the unit.

uMG9820(config-if)# [no] video udp UDP-port-number jitter jitter-value

where

UDP-port-number = UDP port number of the desired incoming session for which the maximum network jitter is to be set.

jitter-value = Maximum network jitter value in milliseconds. The jitter value may be set in the range of 10 to 250 milliseconds.

The default jitter-value is 100 milliseconds.

Example—Set maximum network jitter value for UDP port 5201 to 250 milliseconds for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# video udp 5201 jitter 250
Example—Set maximum network jitter value for UDP port 5201 to default value for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no video udp 5201 jitter
Setting PID Remapping

To remap or drop PIDs within an incoming UDP port session:
uMG9820(config-if)# [no] video UDP UDP-port-number in PID-number {out PID-number | drop}

where

UDP-port-number = UDP port number of the desired incoming session that contains the PID to be remapped

in PID-number = PID number to be remapped or dropped

out PID-number = New PID number (in decimal) in the outgoing program

Example—Remap incoming PID 1000 on UDP port 5201 to PID 1001 for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# video udp 5201 in 1000 out 1001
Example—Drop incoming PID 1000 on UDP port 5201 for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if])# video udp 5201 in 1000 drop
Example—Handle PIDs on UDP port 5201 in default manner for GE port 1:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no video udp 5201
Binding a UDP Port to a VoD Server

Where multiple VoD servers are used, it is possible for video session streams to collide on the same UDP port of the Cisco uMG9820. This can be prevented by using source address filtering (on the addresses of the VoD servers) to prevent collisions. The user is responsible for ensuring that only one VoD server in a multiserver installation is actually streaming video to a given UDP port at any time.

Note In initial releases, only one IP address can be assigned to a given UDP port.

Use the command allow in interface configuration mode, as illustrated below.

To bind a UDP port to a VoD server:

uMG9820(config-if)# [no] allow udp UDP-port-number IP-address

Example—Binding UDP Port 6600 to VoD Server Address 172.16.0.6:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# allow udp 6600 172.16.0.6
Example—Unbinding UDP Port 6600 from VoD Server Address 172.16.0.6:
uMG9820# configure terminaluMG9820(config)# interface gigabitethernet 0/1uMG9820(config-if)# no allow udp 6600 172.16.0.6
Retrieving Input Session Data

To list all the session information, input errors, session state, and continuity count errors:
uMG9820# show interface gigabitethernet slot/port video [session UDP-port-number]

where

slot = 0

port = 1 or 2

UDP-port-number = Number of specific UDP port (optional)

If a specific session UDP port number is provided, then only information on that session is provided. The following information is provided in the response:

•User-defined session parameters

•Session status (inactive, active, invalid Program Specific Information)

•Jitter buffer status (underflow and overflow count) and average fullness

•Continuity count errors

Example—Display all active video sessions on GE port 1:
uMG9820# show interface gigabitethernet 0/1 video
Number of active sessions 0Source Continuity Error Counter 0
Example—Display video session information for UDP port 257 on GE port 1:
uMG9820# show interface gigabitethernet 0/1 video session 257
Current State : ActiveUDP port number : 257 Output QAM number : 0Max Jitter Value : 0 Jitter Overflow : 0Jitter Underflow : 0 Average Fullness : 0Continuity Errors : 0

Note To clear counters, use the clear counters command in terminal configuration mode, as follows:

uMG9820(config)# clear counters

Retrieving Input Session PSI Data

To list all the Program Specific Information (PSI), such as program number, elementary stream ID and PIDs, for a video session:
uMG9820# show interface gigabitethernet slot/port video psi [session UDP-port-number]

where

slot = 0

port = 1 or 2

UDP-port-number = Number of specific UDP port (optional)

If a specific session UDP port number is provided, then only information on that session is provided.

Example—Display PSI information for all active video sessions on GE port 1:
uMG9820# show interface gigabitethernet 0/1 video psi
Inactive PSI Timeout is 0 seconds.Active PSI Timeout is 5 seconds.Queued PSI Timeout is 300 seconds.
Example—Display PSI information for UDP port 5401 on GE port 1:
uMG9820# show interface gigabitethernet 0/1 video psi session 5401
Number of PIDs : 3 Program Number : 1Input PMT PID : 501 Output PMT PID : 32Input PID (Type 81) : 273 Output PID : 33Input PID (Type 3) : 274 Output PID : 34Input PID (Type 2) : 272 Output PID : 35
Configuring Management Ports

The management and CAS ports are addressed using the CLI as Fast Ethernet (FE) ports 1 and 2, respectively. This section covers commands for the following operations:

• Enabling and Disabling an FE Port

• Setting an FE Port IP Address

• Setting an FE Port MAC Address

• Setting an FE Port in DHCP Mode

• Setting the Default Gateway

• Setting Boot Mode

• Retrieving FE Port Statistics

Enabling and Disabling an FE Port

To enable and disable an FE port:
uMG9820(config-if)# [no] shut

Changes to an FE port's state take effect immediately.

Note In the initial release of this product, only FE port 1 is implemented.

Example—Enable FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-fastethernet[0/1])# no shut
Example—Disable FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# shut
Setting an FE Port IP Address

To set the IP address and subnet mask of an FE port:
uMG9820(config-if)# ip address IP-address subnet-mask

where

IP-address = Text string for standard IP address

subnet-mask = Text string for standard subnet mask

Changes to an FE port's IP address take effect immediately.

Example—Set the IP address to 192.168.0.10 and subnet mask to 255.255.255.0 for FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# ip address 192.168.0.10 255.255.255.0
Setting an FE Port MAC Address

To set the MAC address for an FE port:
uMG9820(config-if)# mac-address MAC-address

where

MAC-address = Text string for a standard MAC address in H.H.H form

Changes to an FE port's MAC address take effect following a reload only if the change is first written to the startup configuration. See Managing Configurations.

Example—Set the MAC address to 0000.0123.5678 for FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# mac-address 0000.0123.5678
Setting an FE Port in DHCP Mode

To instruct the FE port to obtain its IP address information from a Dynamic Host Configuration Protocol (DHCP) server:
uMG9820(config-if)# [no] dhcp

Changes to DHCP mode are immediate. When DHCP is disabled, the IP address reverts to the manually specified value.

Example—Enable DHCP mode for FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# dhcp
Example—Disable DHCP mode for FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# no dhcp
Setting the Default Gateway

To set the IP address of the default gateway for FE ports:
uMG9820(config-fastethernet[slot/port])# ip default-gateway IP-address

where

IP-address = Text string for a standard IP address

Example—Set the default gateway address to 192.168.0.1 for FE port 1:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# ip default-gateway 192.168.0.1
Setting Boot Mode

By default, the system boots from internally stored images. However, it is possible to specify the location of the system and kernel images on a remote file system and enable/disable BootP (bootstrap protocol) mode. These files are obtained over an FE management port.

To enable BootP mode, images, and paths:
uMG9820(config-fastethernet[0/1])# [no] boot {system path | kernel path}

where

system path = Remote-system file path for the system image

kernel path = Remote-system file path for the kernel image

Example—Enable BootP mode:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# boot
Example—Set BootP system path to "ramdisk_img.gz":
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# boot system ramdisk_img.gz
Example—Set BootP kernel path to "zImage":
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# boot kernel zImage
Example—Disable BootP mode:
uMG9820# configure terminaluMG9820(config)# interface fastethernet 0/1uMG9820(config-if)# no boot
Retrieving FE Port Statistics

To retrieve packet and buffer statistics for an FE port:
uMG9820# show interface fastethernet slot/port

where

slot = 0

port = 1 or 2

Example—Show packet and buffer statistics for FE port 1:
uMG9820# show interface fastethernet 0/1
FastEthernet0/1 Link Encapsulation:Ethernet HW Address 0050.c206.c299IP Address:192.168.145.130 Broadcast:192.168.145.255 Netmask:255.255.255.0RX Packets:88 Errors:0 Dropped:0 Overruns:0 Frame:0TX Packets:6 Errors:0 Dropped:0 Overruns:0 Carrier:0Collisions:0 TX Queue Length:100RX bytes:11406 (11.1 kb) TX bytes:913 (913.0 b)Interrupt:14Gateway:192.168.145.1 DHCP:Enabled BootP:Disabled
Retrieving FE Port Status

To retrieve the status of an FE port:
uMG9820# show ip interface [brief] fastethernet slot/port

where

brief = Optional keyword to display link status only

slot = 0

port = 1 or 2

You can retrieve the following IP statistics for the specified FE port:

•Link status (up or down)

•Packet and buffer counters

Example—Show the status of FE port 1:
uMG9820# show ip interface fastethernet 0/1
FastEthernet 0/1 is UpInternet address is 192.168.145.130, subnet mask is 255.255.255.0Broadcast address of 192.168.145.255 is validMTU is 1500 bytes, Metric is 1
Example—Show only the link status of FE port 1:
uMG9820# show ip interface brief fastethernet 0/1
Interface IP-address OK Method Status ProtocolFastEthernet0/1 192.168.145.130 YES DHCP Up Up

Tip You can also use show ip interface and show ip interface brief to see the status of all Ethernet ports, as in Retrieving GE Port Status.

Note To clear counters, use the clear counters command in terminal configuration mode as follows:

uMG9820(config)# clear counters

Configuring the Transport Stream

MPEG-2 Program Specific Information (PSI) uses a variety of messages to inform the MPEG receiver about the content of the program stream, and about the streams that are available within the network.

These commands are applied in subinterface mode to an individual QAM channel,

where

slot = 0, 1, 2, 3, 4, 5, or 6

port = 1 or 2

qam = 1 or 2

Table 4-2 lists the MPEG messages and message components that are addressed by the CLI.

Table 4-2 MPEG Messages and Message Components Addressed by the CLI

Message

Description

PAT (Program Association Table)

The first message the receiver attempts to acquire from an MPEG stream. The PAT contains a list of the programs in the stream, as well as a pointer to the PMT for each (see below). It also includes the transport stream ID, or TSID. (See Table 4-3.)

PMT (Program Map Table)

A message that describes the elements of a program. Each program has its own PMT. Once a receiver has acquired a PMT message, it has the information needed to find different elements (for example, video and audio) for that program within the stream.

NIT (Network Information Table)

A list of all of the transport streams within the network, along with their associated RF frequencies. The NIT is identified by means of a network-shared NIT ID (NIT PID). This allows the receiver to know what streams are available. (NIT messages are not always present.)

Table 4-3 shows the default TSID assignment for each QAM channel (subinterface).

This section covers commands for the following operations:

• Setting PAT Message Parameters

• Setting PMT Message Interval

Setting PAT Message Parameters

To set the message field parameters for the outgoing PAT message:
uMG9820(config-subif)# [no] video pat {interval time | tsid tsid | nit-pid pid}

where

time = maximum interval, in milliseconds, between PAT messages

The default value for time is 100 milliseconds.

tsid = Transport stream ID for the output going PAT message. The default value must be unique for each transport stream.

pid = Reference to the NIT PID value in program zero of the PAT message.

The default is to have no reference program zero (program0, which is the NIT PID) in the PAT message.

Example—Set maximum PAT interval to 500 milliseconds on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video pat interval 500
Example—Set the TSID field of the PAT message to 2250 on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video pat tsid 2250
Example—Include program 0 with a reference to PID 4090 in the PAT on slot 1, port 1, QAM channel 2
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video pat nit-pid 4090
Example—Remove program 0 from the PAT message on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# no video pat nit-pid
Setting PMT Message Interval

To set the maximum PMT message interval:
uMG9820(config-subif)# [no] video pmt interval time

where

time = Maximum interval, in milliseconds, between PMT messages

The default value for time is 100 milliseconds.

Example—Set maximum PMT interval to 500 milliseconds on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video pmt interval 500
Configuring and Monitoring QAM Service

This section covers commands for the following operations:

• Enabling and Disabling a QAM Channel

• Setting QAM Modulation

• Setting QAM Frequency

• Setting QAM Output Power

• Retrieving QAM Statistics

• Retrieving QAM Output Video Data

These commands are applied in subinterface mode to an individual QAM channel,

where

slot = 1, 2, 3, 4, 5, or 6

port = 1 or 2

qam = 1 or 2

Enabling and Disabling a QAM Channel

To enable or disable (mute) a QAM channel:
uMG9820(config-subif)# [no] shut

Note The default state for all QAM channels is shut. This prevents interference with existing cable-channel configurations.

Example—Enable QAM output on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# no shut
Example—Disable QAM output on slot 1, port 1, QAM channel 2:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# shut
Setting QAM Modulation

To set the modulation rate for all QAM outputs on the selected QAM card:
uMG9820(config-subif)# [no] video format type

where

type = Modulation scheme. Values are either 64QAM or 256QAM.

The default value for type is 256QAM.

Note The modulation for both channels for a port is set when either channel 1 or channel 2 is addressed. (64QAM is not available in initial releases.)

Example—Set the modulation rate for all QAM outputs on slot 1, port 1, QAM channel 2 to 256QAM:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# video format 256QAM
Example—Set the modulation rate for all QAM outputs on slot 1, port 1, QAM channel 2 to default value:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.2uMG9820(config-subif)# no video format
Setting QAM Frequency

Figure 4-1 illustrates the QAM channel 1 and channel 2 frequencies in relation to the center frequency.

Figure 4-1 QAM Channel Frequencies

To set the center frequency of the selected QAM channel:
uMG9820(config-subif)# video frequency frequency

where

frequency = QAM channel center frequency in Hz, from 225000000 to 900000000.

Note The frequency for both channels for a port is set when either channel 1 or channel 2 is addressed, and is determined by the center frequency.

Caution Do not set the two 6-MHz QAM channels within a 12-MHz-wide RF channel to the same center frequency. See Special Issues: Selecting QAM Frequencies to Avoid Overlap.

Example—Set the center frequency of slot 1, port 1, QAM channel 1 to 850 MHz:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.1uMG9820(config-subif)# video frequency 850000000

Note In this example, the center frequency of QAM 1/1.2 is automatically adjusted to 856000000 Hz.

Special Issues: Selecting QAM Frequencies to Avoid Overlap

The frequencies on an RF chain (or block: the circuitry providing the maximum bandwidth of a QAM port—from 3 MHz below the bottom center frequency to 3 MHz above the top center frequency) must not overlap those of the other port on the same QAM card. (For this discussion, the two ports on the same card are referred to as adjacent ports.) The settings of the QAM frequencies (center frequencies) on each channel determine the upper and lower bounds of the RF chain.

Note To maximize reliability and isolation, each RF chain on a given QAM card is a separate circuit, with its own local oscillator (LO). However, if frequencies on both RF chains on a card are set too closely to each other, they can be amplified by the LOs on the adjacent chain—resulting in spurious products. The rules presented in this section ensure the necessary signal isolation.

Note the following rules for selecting QAM frequencies (center frequencies):

1. The two 6-MHz QAM channels within a 12-MHz-wide RF chain cannot be set to the same center frequency. The center frequency of the QAM channel on slot/port.1 is always 6 MHz lower than the center frequency of the QAM channel on slot/port.2.

2. The two 12-MHz-wide RF chains on any QAM card (one chain from port 1 and the other from port 2) must not overlap. The center frequencies for the 6-MHz QAM channels on slot/1.1 and slot/1.2 must be different from the center frequencies for the 6-MHz QAM channels on slot/2.1 and slot/2.2.

Caution The center frequencies of each of the two 12-MHz RF chains must be at least 12 MHz apart.

3. As long as rule 2 is strictly adhered to on each QAM card, it is valid to set up more than one QAM card in a Cisco uMG9820 chassis with the same frequency assignments.

Table 4-4 lists both invalid (examples 1 and 2) and valid (examples 3 and 4) QAM center frequency schemes. For an explanation of each example, see the Notes following the table.

Note These frequency assignments are for illustration only.

•Where the assignments are invalid, it is because the RF chains on the ports on the same card overlap completely or partially.

•Where the assignments are valid, the same frequencies can be assigned to more than one QAM card in a chassis—as long as the above rules are not violated on those cards.

Notes

•Example 1 (Invalid): RF chains on adjacent ports overlap completely.

•Example 2 (Invalid): RF chains on adjacent ports overlap partially.

•Example 3 (Invalid): RF chains on adjacent ports overlap (the top frequency of one chain is the same as that on the bottom of the chain on the adjacent port).

•Example 4 (Valid): RF chains overlap, but are on the same port.

•Example 5 (Valid): RF chains do not overlap, and are on the same port.

•Example 6 (Valid): RF chains do not overlap, and are on different adjacent ports.

Setting QAM Output Power

To set the combined output power level for a QAM port:
uMG9820(config-subif)# video power power

where

power = QAM power assignment in dBmV. The value can be from 50 to 60, in one-unit increments.

Example—Set the output power level of slot 1, port 1, QAM channel 1 to 50 dBmV:
uMG9820# configure terminaluMG9820(config)# interface qam 1/1.1uMG9820(config-subif)# video power 50

Note The output power for both channels for a port is set when either channel 1 or channel 2 is addressed.

Message	Description
PAT (Program Association Table)	The first message the receiver attempts to acquire from an MPEG stream. The PAT contains a list of the programs in the stream, as well as a pointer to the PMT for each (see below). It also includes the transport stream ID, or TSID. (See Table 4-3.)
PMT (Program Map Table)	A message that describes the elements of a program. Each program has its own PMT. Once a receiver has acquired a PMT message, it has the information needed to find different elements (for example, video and audio) for that program within the stream.
NIT (Network Information Table)	A list of all of the transport streams within the network, along with their associated RF frequencies. The NIT is identified by means of a network-shared NIT ID (NIT PID). This allows the receiver to know what streams are available. (NIT messages are not always present.)
