Cisco Systems VIP-4R/4T manual Write the new configuration to memory, as follows

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

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

For complete descriptions of software configuration commands, refer to the publications listed in the 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.
