Configuring the 12E/2FE Interfaces 6-5

Shutting Down an Interface

Step 3 Specify the slot/port address of the interface you want shut down by entering the

interface fastethernet (for interface port numbers 0 and 1) or interface ethernet (for

interface port numbers 2 through 13) command. The following example is for the ﬁrst

12E/2FE interface in port adapter slot 1:

Router(config)# interface fastethernet 1/0

Note For the Cisco 7206 router shelf, the interface speciﬁed in Step 3 would include a

shelf number. For example, the command interface fastethernet 5/1/0 would specify the

ﬁrst 12E/2FE interface in port adapter slot 1 of Cisco 7206 router shelf 5.

Step 4 Enter shutdown and then exit to return to conﬁguration mode.

Router(config-if)# shutdown

Router(config-if)# exit

Router(config)#

Step 5 Repeat Step 3 and Step 4 to shut down any additional existing interfaces. When you have

ﬁnished, press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit

conﬁguration mode and return to the EXEC command interpreter prompt as follows:

Router(config)# Ctrl-Z

Router#

Step 6 Save 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 Verify new interfaces are now in the correct state (shutdown) by entering the show

interface fastethernet (for interface port numbers 0 and 1) or show interface ethernet

(for interface port numbers 2 through 13) command. The follow example is for the ﬁrst

12E/2FE interface in port adapter slot 1:

Router# show int fastethernet 1/0

FastEthernet1/0 is administratively down, line protocol is down

Hardware is TSWITCH, address is 0000.0000.0000 (bia 0000.0000.0000)

Note For the Cisco 7206 router shelf, the show interfaces command requires a shelf

number in the format show interfaces type shelf number/port adapter slot/interface.
