POE COMMANDS

power inline

auto --> Turns on the device discovery protocol and supplies power to the device.

never --> Turns off the device discovery protocol and stops supplying power to the device.

nfvis(config-switch)# interface gigabitEthernet 1/0

nfvis(config-switch-if)# power inline auto/never

nfvis(config-switch-if)# commit

nfvis(config-switch-if)# end

power inline limit

Specifies the power limit for the port in milliwatt. Valid range is from 0 to 60000. The default value is 30W

nfvis(config-switch)# interface gigabitEthernet 1/0

nfvis(config-switch-if)# power inline limit 30000

nfvis(config-switch-if)# commit

nfvis(config-switch-if)# end

power inline powered-device

nfvis(config-switch)# interface gigabitEthernet 1/0

nfvis(config-switch-if)# power inline powered-device ip-phone

nfvis(config-switch-if)# commit

nfvis(config-switch-if)# end

power inline priority

power inline priority {critical | high | low}

critical --> Specifies that the device operation is critical.

high--> Specifies that the device operation is high priority.

low--> Specifies that the device operation is low priority

nfvis(config-switch)# interface gigabitEthernet 1/0

nfvis(config-switch-if)# power inline priority high

nfvis(config-switch-if)# commit

nfvis(config-switch-if)# end

How Switch differntiates traffic from computer & ip phone ?

we have a trunk between our switch and IP phone. The port on the IP phone that connects to the computer is an access port.

The IP phone will forward all traffic from the computer to the switch untagged but traffic from itself (IP phone) will be tagged.

The only two VLANs that are allowed are the access and voice VLAN.

SW1(config)# interface GigabitEthernet 0/1

SW1(config-if)# switchport mode access

SW1(config-if)# switchport access vlan 100

SW1(config-if)# switchport voice vlan 101

SW1(config-if)# exit
