Examples
The following example command displays the PoE status for an 802.3bt enabled interface:
Device# show power inline upoe-plus gigabitEthernet 1/0/23
Codes: DS - Dual Signature device, SS - Single Signature device
SP - Single Pairset device
Interface Admin Type Oper-State Power(Watts) Class Device Name
State Alt-A,B Allocated Utilized Alt-A,B
----------- ------ ---- ---------- --------- --------- ------- -----------
Gi1/0/4 auto SP on 4.0 3.8 1 Ieee PD
Gi1/0/15 auto SS on,on 60.0 10.5 6 Ieee PD
Gi1/0/23 auto DS on,on 45.4 26.9 3,4 Ieee PD

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 allocated drops to 30 W. The following is the output of the show power inline detail command in such a scenario:
