Cisco Systems 3825 manual Extended Availability Drop and Insert Eadi, Configuring GSM-Abis Links

Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line

Configuration Sequence

Step 6 Enable keepalive packets on the interface and specify the number of times the keepalive packets will be sent without a response before bringing down the interface.

Router(config-if)# keepalive [period]

Where period is an optional integer value in seconds greater than 0. The default is 10.

For example, the following command indicates the number of times the keepalive packets will be sent as 1:

Router(config-if)# keepalive 1

Extended Availability Drop and Insert (EADI)

EADI capabilities must be disabled on the Cisco 3825 router (using the disable-eadiglobal configuration command) to avoid a double-termination situation upon router reboot when the Cisco 3825 router is being used in a redundant configuration.

To disable EADI, follow these steps, while in the global configuration mode:

Step 1 Disable EADI.

Router(config)# disable eadi

Configuring GSM-Abis Links

Note The following is an example of configuring an E1 on the Cisco 2-port T1/E1-RAN interface card in a Cisco 3825 router.

Use the following instructions to perform a basic Global System for Mobile Communications (GSM)-Abis configuration on the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router, by entering the following Cisco IOS commands at the router prompt (see the “Understanding the Cisco 3825 Router Interface Numbering” section on page 3-1for information about slot and port numbering on the Cisco 3825 router). You might also need to enter other configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.

Note In the following procedure, press the Return key after each step unless otherwise noted. At any time, you can exit the privileged level and return to the user level by entering disable at the Router# prompt.

To configure the GSM-Abis attributes, follow these steps while in the global configuration mode:

Step 1 Set the card type for the Cisco 2-port T1/E1-RAN interface card.
