Chapter 4 Configuring the Multichannel DS1/PRI Interfaces
Configuring the Interfaces
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1:23,
changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1:23,
changed state to up
Router(config-controller)#
For the Cisco 7301 routers:
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:23,
changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:23,
changed state to up
Router(config-controller)#
For the Cisco 7401ASR routers:
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:23,
changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial4/1:23,
changed state to up
Router(config-controller)#
For the VIP:
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:23,
changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:23,
changed state to up
Router(config-controller)#
Note
In the preceding examples, the line-protocol status for time slot 24 (listed in the output as time
slot 23) represents the entire PRI group.
slot 23) represents the entire PRI group.
Step 8
Specify the interface to modify by entering the interface serial subcommand, followed by the interface
address of the interface you plan to configure. For multichannel T1 ISDN PRI, the PRI group is
configured using time slot 24, which is recognized by the system as time slot 23 (for example, the VIP2
would be 3/1/1:23).
address of the interface you plan to configure. For multichannel T1 ISDN PRI, the PRI group is
configured using time slot 24, which is recognized by the system as time slot 23 (for example, the VIP2
would be 3/1/1:23).
Step 9
If IP routing is enabled on the system, assign an IP address and subnet mask to the interface with the
ip address configuration subcommand as in the following example:
ip address configuration subcommand as in the following example:
Router(config-int)# ip address 1.1.15.1 255.255.255.0
Router(config-int)#
Step 10
Add any other configuration subcommands required to enable routing protocols and adjust the interface
characteristics.
characteristics.
Step 11
Use the no shutdown command to re enable the interfaces.
Step 12
After including all of the configuration subcommands, to complete the configuration, press Ctrl-Z (hold
down the Control key while you press Z) to exit configuration mode.

Step 13
Write the new configuration to memory:
