Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
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 9 To configure PPP encapsulation, enter the following command:
Router(config-if)# encapsulation ppp
Step 10 Enable keepalive packets on the interface and specify the number of times keepalive packets are sent
without a response before bringing down the interface:
Router(config-if)# keepalive [period [retries]]
Step 11 Exit interface configuration mode.
Router(config-if)# exit
Configuring T1 Controllers
Use the following instructions to perform a basic T1 controller configuration: specifying the T1
controller, specifying the framing type, specifying the line code form, specifying the channel-group and
time slots to be mapped, configuring the cable length, configuring the serial interface, configuring PPP
encapsulation, and enabling keepalive packets. You might also need to enter other configuration
commands, depending on the requirements for your system configuration and the protocols you plan to
route on the 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.
To configure the T1 interfaces, follow these steps while in the global configuration mode:
Step 1 Specify the controller that you want to configure. Controller T1 0/0 maps to the T1/E1 HWIC card in
HWIC slot 0.
Router(config)# controller t1 slot/port
Step 2 Specify the framing type.
Router(config-controller)# framing esf
Step 3 Specify the line code format.
Router(config-controller)# linecode b8zs
Step 4 Use the mode command to set the controller in asynchronous transfer mode (ATM) or
channel-associated signaling (CAS) mode.
Router(config-controller)# mode {atm | cas}
Step 5 Specify the channel-group and time slots to be mapped. After you configure a channel-group, the serial
interface is automatically created.
Note The default speed of the channel-group is 56.
