The show power inline detail command is enhanced to display 802.3bt-complaint device information such as the Operational Status of the device, IEEE Class
of the device, Physical Assigned Class, Allocated Power, (Power) Measured at the port.
Consider a scenario where a Class 5 Single Signature powered device sends a request through LLDP to lower the power allocated
by PSE. Because of this, the power that is allocated drops to 30 W. The following is the output of the show power inline detail command in such a scenario:

The following is a sample output of the show power inline priority command when the port priority is not configured on an interface. The admin priority, as shown below will be n/a and the
operational priority will be the default priority based on the line card slot.

The following is a sample output of the show power inline priority command when the port priority is configured as 5. With this configuration, both the admin and the operational priority will
change to 5.
Device(config)# show power inline priority gigabitEthernet 1/0/1
Device(config-if)# power inline port priority 5
Device# show power inline priority gigabitEthernet 1/0/1

The following is a sample output of the show power inline priority command when you configure a priority on static ports. The operation priority will change to 0, as static ports have the
highest priority and will be the last to shutdown.
Device(config)# interface gigabitEthernet 1/0/1
Device(config-if)# power inline static
Device # show power inline priority gigabitEthernet 1/0/1
