Below you will find the examples of how to bring up and down an interface on a CISCO switch or router.
On the CISCO command-line interface, there is the shutdown interface configuration command to disable an interface and the no shutdown command to enable it.
I will show the examples of these commands, as well as how to check an interface status using the show interfaces status command. (more…)
Execute one of the following commands to check the status of fans on Cisco equipment.
Use the ‘show environment | include fan-tray‘ command to check Fan-Tray status.
# show environment | include fan-tray system minor alarm on fan-tray 1 fan-fail (raised 00:22:13 ago) fan-tray 1: fan-tray 1 type: WS-C6K-9SLOT-FAN fan-tray 1 version: 1 fan-tray 1 fan-fail: failed
Or use ‘show environment status fan-tray‘ command.
# show environment status fan-tray fan-tray 1: fan-tray 1 type: WS-C6K-9SLOT-FAN fan-tray 1 version: 1 fan-tray 1 fan-fail: failed
You can also check temperature using ‘show environment temperature‘ command.
# show environment temperature VTT 1 outlet temperature: 24C VTT 2 outlet temperature: 26C VTT 3 outlet temperature: 25C module 1 outlet temperature: 24C module 1 inlet temperature: 26C module 1 device-1 temperature: 33C module 1 device-2 temperature: 33C RP 1 outlet temperature: 30C RP 1 inlet temperature: 34C EARL 1 outlet temperature: 30C EARL 1 inlet temperature: 26C
Type the following commands to create/edit the description of the port ‘FastEthernet 0/1’ on CISCO switch or router:
# enable # configure terminal (config)# interface FastEthernet 0/1 (config-subif)# description This is 1st Port of My Switch (config-subif)# end # write
To display a description and a status of an interface, use the ‘show interfaces description‘ command:
# show interfaces FastEthernet 0/1 description Interface Status Protocol Description FastEthernet 0/1 up up This is 1st Port of My Switch
