Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Router(config-controller)# channel-group 0 timeslots 1-24 speed 56
Step 6 Configure the cable length.
Router(config-controller)# cablelength {long [-15db | -22.5db | -7.5db | 0db] short [110ft
| 220ft | 330ft| 440ft | 550ft | 600ft]}
Step 7 Exit controller configuration mode.
Router(config-controller)# exit
Step 8 Configure the serial interface. Specify the T1 slot (always 0), port number, and channel-group.
Router(config)# interface serial slot/port:channel
Step 9 Enter the following command to configure PPP encapsulation.
Router(config-if)# encapsulation ppp
Step 10 Enable keepalive packets on the interface and specify the number of times that keepalive packets will be
sent without a response the interface is brought down:
Router(config-if)# keepalive [period [retries]]
Step 11 Exit to global configuration mode.
Router(config-if)# exit
Configuring ATM IMA
Inverse multiplexing provides the capability to transmit and receive a single high-speed data stream over
multiple slower-speed physical links. In inverse multiplexing over ATM (IMA), the originating stream
of ATM cells is divided so that complete ATM cells are transmitted in round-robin order across the set
of ATM links. Follow these steps to configure ATM IMA on the Cisco MWR 2941.
Step 1 Use the card type command to specify the slot and port number of the E1 or T1 interface.
Router(config)# card type e1 0 0
Step 2 Specify the controller interface on which you want to enable IMA.
Router(config)# controller E1 0/4
Router(config-controller)#
Step 3 Set the clock source to internal.
Router(config-controller)# clock source internal
Step 4 Use the ima-group command to assign the interface to an IMA group, and set the scrambling-payload
parameter to randomize the ATM cell payload frames. This command assigns the interface to IMA group
0.
Router(config-controller)# ima-group 0 scrambling-payload
Note This command automatically creates an ATM0/IMAx interface.
Step 5 To add another member link, repeat Step 1 to Step 4.
Step 6 Type exit to exit the controller interface.
