Cisco Systems 3825 manual Specify the link that is included in an IMA group

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

Configuration Sequence

Note With Cisco IOS Release 12.4(16)MR1 and later, the Cisco 3825 router supports the AIM-ATM-8 card. The Cisco 3825 router supports up to 12 ATM ports with the AIM-ATM-8 card installed in slot 0 and up to 8 ATM ports for AIM with the AIM-ATM-8 card installed in slot 1.

The AIM for ATM card (AIM-ATM) supports up to four independent ATM links.

To determine which AIM for ATM card is installed in your router, use the show diagnostics command in privileged EXEC mode.

To configure a Cisco 3825 router for IMA, follow these steps while in the global configuration mode:

Step 1 Enter interface configuration mode and specify the location of the interface.

Router(config)# interface atmslot/subslot/port

Where:

•slot—Specifies the slot number of the VWIC/HWIC previously assigned to the AIM for ATM (Step 2 of the “Configuring UMTS Links” procedure on page 4-24).

•subslot—Specifies the subslot number of the VWIC/HWIC previously assigned to the AIM for ATM card (Step 2 of the “Configuring UMTS Links” procedure on page 4-24).

•port—Specifies the port on the VWIC/HWIC previously assigned to the AIM for ATM card (Step 3 of the “Configuring UMTS Links” procedure on page 4-24).

For example, the following command configures the VWIC/HWIC in logical slot 0 (physical slot 0), subslot 0, port 1 located on the motherboard of the Cisco 3825 router to be used for ATM traffic:

Router(config)# interface ATM0/2/0

Router(config-if)#

Note To see a list of the configuration commands available to you, enter ? at the prompt or press the Help key while in the configuration mode.

Step 2 Disable the IP address configuration for the physical layer interface. This and other protocol parameters should be configured on the IMA interface.

Router(config-if)# no ip address

Step 3 Disable the Interim Local Management Interface (ILMI) keepalive parameters.

Router(config-if)#no atm ilmi-keepalive

Step 4 Specify the link that is included in an IMA group.

Router(config-if)# ima-groupgroup-number

Where group-numberspecifies the group number of the IMA group.

For example, the following command specifies the group number of the IMA group as 0:

Router(config-if)# ima-group 0

Step 5 Randomize the ATM cell payload frames.

Router(config-if)# scrambling-payload

Step 6 Perform Steps 1 to 5 to add another member link.
