Disabling or re-enabling PoE port operation


[no] interface <port-list> power-over-ethernet

Re-enables PoE operation on <port-list> and restores the priority setting in effect when PoE was disabled on <port-list>.

The no form of the command disables PoE operation on <port-list>.

Default: All PoE ports are initially enabled for PoE operation at Low priority. If you configure a higher priority, this priority is retained until you change it.


For PoE, disabling all ports allows the 22 watts of minimum PoE power or the 38 watts for PoE+ power allocated for the module to be recovered and used elsewhere. You must disable ALL ports for this to occur.
