interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>
Note
If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
poe poe-shutdown [port <portlist>]
<portlist> is the port on which you want to disable PoE. The default is enable.
To return power to the port, enter no poe-shutdown [port <portlist>].
