show power
show power
To display information about the power status, use the show power command.
show power [available | capabilities | detail | inline {[interface] detail | consumption default |
module mod detail}} | module | status | supplies]
Syntax Description
Defaults This command has no default settings.
Command Modes Privileged EXEC mode
Command History
Usage Guidelines If a powered device is connected to an interface with external power, the switch does not recognize the
powered device. The Device column in the output of the show power inline command displays as
unknown.
If your port is not capable of supporting PoE, you will receive this message:
Power over Ethernet not supported on interface Admin
The show power inline interface | module command displays the amount of power that is used to operate
a Cisco IP Phone. To view the amount of power requested, use the show cdp neighbors command.
Because FPGAs and other hardware components on the WS-X4548-RJ45V+ and WS-X4648-RJ45V+E
modules consume PoE, the operating PoE consumption for an 802.3af-compliant module can be nonzero
when there are no powered devices attached to the module. The operating PoE can vary by as much as
20 W because of fluctuations in the PoE that is consumed by the hardware components.
