Configuring 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 the new interface is now in the correct state (shut down) using the
show controllers command (followed by the interface type and interface address of the interface) to
display the specific interface.
Step 6
Reenable the interface by doing the following:
a.
Repeat Step 3 to reenable an interface. Substitute the no shutdown command for the shutdown
command.
b.
Repeat Step 4 to write the new configuration to memory. Use the
copy running-config startup-config command.
c.
Repeat Step 5 to verify that the interface is in the correct state. Use the show controllers command
followed by the type and address of the controller.
