Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
• 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 ATM slot /IMA <group-number>
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]
