70 VIP-4R/4T Installation and Configuration
VIP Port Adapter Functions
Step 5
To shut down additional interfaces, enter the slot/port address of each additional interface
followed by the shutdown command. When you have entered all the interfaces to be shut
down, press Ctrl-Z (hold down the Control key while you press Z) to exit Configuration
mode and return to the EXEC command interpreter prompt, as follows:
Router(config-int)# int serial 1/1/0
Router(config-int)# shutdown
Router(config-int)# int serial 1/1/1
Router(config-int)# shutdown
Router(config-int)# ^Z
Router#
Step 6
Write the new configuration to memory, as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored.
Step 7
To verify that new interfaces are now in the correct state (shutdown), use the show
interface serial slot/port command to display the specific interface, or use the show
interfaces command, without variables, to display the status of all interfaces in the system.
Router# show int serial 1/1/0
Serial 1/1/0 is administratively down, line protocol is down
Hardware is cxBus VIP
[display text omitted]
Step 8
To reenable the interfaces, repeat the previous steps, but use the no shutdown command in
Step 4, then write the new configuration to memory, as follows:
Router(config)# int serial 1/1/0
Router(config-int)# no shutdown
Router(config-int)# ^Z
Router# copy running-config startup-config
[OK]
Router# show int serial 1/1/0
Serial 1/1/0 is up, line protocol is up
Hardware is cxBus VIP

section “If You Need More Configuration Information” on page 2.
Configuring Interfaces
Following are instructions for a basic configuration: enabling an interface, specifying IP routing, and
setting up external timing on a DCE interface. You might also need to enter other configuration
subcommands, depending on the requirements for your system configuration and the protocols you
plan to route on the interface. For complete descriptions of configuration subcommands and the
configuration options available for serial interfaces, refer to the appropriate software documentation.
Cisco 7000 series and Cisco 7500 series routers identify an interface address by its slot number and
port number (port numbers 0 through 7, depending on the interface processor type) in the format
slot/port. Each 4T port adapter contains four serial interfaces.
