Installation guide

Software Configuration 5-15

Additional Configuration Tasks

Router(config-if)# ip address 10.1.15.1 255.255.255.0

Router(config-if)#

Step 9 Add any additional conﬁguration commands required to enable routing

protocols and adjust the interface characteristics. Refer to the Cisco IOS

conﬁguration guides and command references for more information on

conﬁguration subcommands.

Step 10 When you have completed the conﬁguration, press Ctrl-Z to exit conﬁguration

mode.

Step 11 Write the new conﬁguration to memory, as follows:

Router# write memory

The system displays a conﬁrmation message when the conﬁguration is saved.

Step 12 Enter the disable command to return to the user level:

Router# disable

Router>

Step 13 Enter the show commands to check the conﬁguration of the interface.

This completes the procedure to conﬁgure a channelized T1 interface.

Conﬁguring the E1 Interface

If you installed a new channelized E1/ISDN PRI (CE1/PRI) network processor module or

if you want to change the conﬁguration of an existing network processor module, you must

enter conﬁguration mode to conﬁgure or reconﬁgure the interface. If you replaced a

CE1/PRI module that was previously conﬁgured, the system will recognize the new

CE1/PRI module and bring it up with the existing conﬁguration.

When you have veriﬁed that the new CE1/PRI module is recognized by the router, use the

conﬁgure command to conﬁgure the new CE1/PRI module. Have the following

information ready when you begin your conﬁguration:

• E1 information—for example, line code and framing type

• Channel group and time-slot mapping

• Protocols and encapsulations you plan to use on the new interfaces
