Configuring Host Router and Cisco Analog Video Gateway Module Interfaces

Last Updated: August 17, 2009

To configure the Cisco Analog Video Gateway network module after it is installed in your host Cisco Integrated Services Router (ISR), you need to configure the following:

•Cisco ISR external interface to an external network link using the Cisco IOS CLI for setting standard router settings

•Cisco ISR internal interface to the Cisco Analog Video Gateway module, using the Cisco IOS CLI for setting the network module IP address and default gateway router

•Cisco Analog Video Gateway module internal interface to the host router, using network module firmware for setting application settings

•Cisco Analog Video Gateway module external interface to an external link, using the module firmware for servicing external requests

Whenever possible, configuration and management of the Cisco Analog Video Gateway module should be configured using the Video Surveillance Operations Manager (VSOM) graphical user interface.

The following sections describe the tasks required to configure the host router and Cisco Analog Video Gateway module interfaces:

•Before Configuring the Cisco Analog Video Gateway

•Entering and Exiting the Command Environment

•Configuring Interfaces

•Opening and Closing a Network Module Session

•Configuring the Cisco Analog Video Gateway Profiles

Before Configuring the Cisco Analog Video Gateway

Complete the following prerequisites for the ISR, network module, and file server before you attempt to configure the Cisco Analog Video Gateway:

Cisco ISR

•Plan software installations, upgrades, or downgrades for times when you can take out of service or off line all applications that run on the host router.

•Ensure that your Cisco router serves as your host router, running the appropriate Cisco IOS release. To learn which release your router is currently running, check the output from the show version command.

Note When minimum release requirements are met, you can change images on either the host router or on the Cisco Analog Video Gateway module, without affecting the other image.

Network Module

•If it is not already installed at the factory, install the Cisco Analog Video Gateway network module into the host router with sufficient physical memory (see Table 1) to accommodate the Cisco Analog Video Gateway application software.

Note For detailed information on hardware installation, see Installing Cisco Network Modules in Cisco Access Routers.

•Before swapping out a Cisco Analog Video Gateway module in an existing system, perform a full backup of all data.

•After the swap, restore the data.

Note For more information, see the "Backing Up and Restoring Configurations" section on page 19.

•Note the Cisco Analog Video Gateway module location in the host router:

–slot: Number of the host router chassis slot for the module. After you install the module, you can obtain this information by using the router show running-config command.

–unit: Number of the daughter card on the module. This value should be 0.

Note You need this information for the "Interface Configuration Tasks" section and the "Opening and Closing a Network Module Session" section.

File Server

•Verify that your download File Transfer Protocol (FTP) or Trivial File Transfer Protocol (TFTP) file server is accessible:

–FTP file server: Use for installations, backups, and data restores.

–TFTP file server: Use for boot helper operations to recover from a failed installation.

•Configure the Cisco Analog Video Gateway module software only from a console that connects to a serial console port on the host router.

Note See the Cisco Analog Video Gateway Installation and Upgrade Guide for more information.

•Access the Cisco Analog Video Gateway module software only by first accessing one of the following:

–Cisco IOS command-line interface (CLI)

–Cisco Analog Video Gateway XML application programming interface (API)

Entering and Exiting the Command Environment

This section describes the procedures for entering and exiting the command environment, in which the Cisco Analog Video Gateway configuration commands are executed. The following sections describe these procedures:

•EXEC and Configuration Modes

•Entering the Command Environment

•Exiting the Command Environment

EXEC and Configuration Modes

The Cisco Analog Video Gateway user EXEC, privileged EXEC, and configuration command modes are similar to the user EXEC, privilege EXEC, and configuration modes for Cisco IOS CLI commands. The description for each command of this section indicates the command mode.

The following sections describe the tasks that are necessary for configuring the host router and network module interfaces:

•Interface Configuration Tasks

•Opening and Closing a Network Module Session

Interface Configuration Tasks

The first configuration task is to set up the Cisco Analog Video Gateway module interface to the host router and to its external links. This enables you to access the module so that you can install and configure the Cisco Analog Video Gateway software application.

Steps 1 and 2 open the host router CLI and accesses the router interface to the Cisco Analog Video Gateway module. The remaining steps configure the interface.

Note If you lose power or connection during any of the following procedures, the system usually detects the interruption and tries to recover. If it fails to do so, fully reinstall the system using the boot helper.

SUMMARY STEPS

Opening and Closing a Network Module Session

This section describes how to open and close a session on the Cisco Analog Video Gateway module.

Note•Before you install your application software, opening a session brings up the boot loader. The boot loader is a small set of system software that runs when the system first powers up. It loads the operating system from the disk (external CompactFlash memory) or network, which loads and runs the Cisco Analog Video Gateway application. The boot loader may optionally load and run the boot helper. After you install the software, opening a session brings up the application.

•You can conduct only one session at a time.

•The Steps 1 and 2 open the host-router CLI and access the module. The remaining steps configure the module and return you to the host-router CLI.

SUMMARY STEPS

From the Host-Router CLI

1. enable

2. service-module video-service-engine slot/0 status

3. service-module video-service-engine slot/0 session

From the Service-Module Interface

4. Network module configuration commands

5. Control-Shift-6 x
