Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Router(config-controller)# exit
Router(config)#
Step 7 Specify the slot location and port of IMA interface group.
Router(config-if)# interface ATM slot/IMA group-number
• 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 To explicitly configure the IMA group ID for the IMA interface, you may use the optional ima
group-id command. 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 8 Disable the IP address configuration for the physical layer interface.
Router(config-if)# no ip address
Step 9 Specify the ATM bandwith as dynamic.
Router(config-if)# atm bandwith dynamic
Step 10 Disable the Interim Local Management Interface (ILMI) keepalive parameters.
Router(config-if)# no atm ilmi-keepalive
Note The above configuration has one IMA shorthaul with two member links (atm0/0 and atm0/1).
Configuring a Multilink Backhaul Interface
A multilink interface is a virtual interface that represents a multilink PPP bundle. The multilink interface
coordinates the configuration of the bundled link, and presents a single object for the aggregate links.
However, the individual PPP links that are aggregated must also be configured. Therefore, to enable
multilink PPP on multiple serial interfaces, you first need to set up the multilink interface, and then
configure each of the serial interfaces and add them to the same multilink 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.
The Cisco MWR 2941 router can support up to 16 E1/T1 connections through the multilink interface,
ranging from 12 bundles of 1 E1/T1 each to a single bundle containing 16 E1/T1 bundles.
