Chapter 4 Configuring the 6T3 Line Card

Configuring the Interfaces

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or

exit to exit configuration mode and return to the EXEC command interpreter.

Note If you need to shut down additional interfaces, enter the interface serial command (followed by

the interface address of the interface) for each of the interfaces on your line card. Use the no

shutdown command to enable the interface.

Step 4 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config

[OK]

Router#

The system displays an OK message when the configuration has been stored in NVRAM.

Step 5 Verify that new interfaces are now in the correct state (shut down) using the

show interfaces command (followed by the interface type and interface address of the interface) to

display the specific interface. Table 4-2 provides examples.
