Configuration Sequence Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line • 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) 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)# Step 7 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 8 Disable the Interim Local Management Interface (ILMI) keepalive parameters. Router(config-if)# no atm ilmi-keepalive Step 9 Specify the link that is included in an IMA group. Router(config-if)# ima-group group-number Where group-number specifies 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 10 Randomize the ATM cell payload frames. Router(config-if)# scrambling-payload Step 11 Specify the slot location and port of IMA interface group. Router(config-if)# interface ATMslot/IMA Where: • slot-Specifies the slot location of the ATM IMA port adapter. • group-number-Specifies the group number of the IMA group. For example, the following command specifies the slot number as 0 and the group number as 0: Router(config-if)# interface ATM0/IMA0 Note Should you desire, the optional ima group-id command can be used to explicitly configure the IMA Group ID for the IMA interface. You cannot configure the same IMA Group ID on two different IMA interfaces; therefore, if you configure an IMA Group ID with the system-selected default ID already configured on an IMA interface, the system toggles the IMA interface to make the user-configured IMA Group ID the effective IMA Group ID. At the same, the system toggles the original IMA interface to select a different IMA Group ID. Step 12 Create an ATM path on the UMTS Iub interface, enter the following command: Router(config-if)# atm umts-iub Step 13 Disable the ILMI keepalive parameters. Router(config-if)# no atm ilmi-keepalive Step 14 Create an ATM PVC: Router(config-if)# pvc [name] vpi/vci [qsaal] 4-42 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide OL-15667-03
