Power Class
Shows the power class of the PD detected on the indicated port. Classes include:
•
0:
0.44 to 12.95 watts
•
1:
0.44 to 3.84 watts
•
2:
3.84 to 6.49 watts
•
3:
6.49 to 12.95 watts
•
4:
For PoE+; up to 25.5 watts can be drawn by the PD
MPS Absent Cnt
Shows the number of times a detected PD has no longer requested power from the port.
Each occurrence generates an Event Log message. ("MPS" refers to the "maintenance
power signature.")
Short Cnt
Shows the number of times the switch provided insufficient current to a connected PD.
Current
The total current, in mA, being delivered to PDs.
If you want to view the PoE status of ports A6 and A7, you would use
show power-over-ethernet A6-A7
to
display the data:
show power-over-ethernet <port-list>
output
switch(config)# show power-over-ethernet slot A6-A7

802.3bt support
IEEE 802.3bt standard enables delivering up to 90W of power across a network cable supporting all standardized
copper link speeds of up to 10G-BaseT, commonly referred to as Power over Ethernet (PoE) or 4-Pair PoE.
Earlier IEEE 802.3af and IEEE 802.3at PoE specifications permit Type 1 and 2 PSEs to deliver power over 2-
pairs of a 4-pair Ethernet cable. The IEEE 802.3bt specifications permit Type 3 and 4 PSEs to deliver power over
all 4-pairs of the Ethernet cable enabling higher efficiency and power delivery to remote devices.
