Chapter
Configuring the PA-2CE1 Interfaces
Step 3
Shut down the interface by entering the interface serial subcommand (followed by the interface address
of the interface), and then enter the shutdown command. Table 4-2 shows the command syntax.
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.
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 4-3 provides examples.
