Power Over Ethernet (PoE+) Operation
Displaying the Global PoE Status
Syntax: show power-over-ethernet <port-list > (Continued)
• Power Denied Cnt: Shows the number of times PDs requesting
power on the port have been denied due to insufficient power
available. Each occurrence generates an Event Log message.
• Voltage: The total voltage, in dV, being delivered to PDs.
• Power: The total power, in mW, being delivered to PDs.
• LLDP Detect: Port is enabled or disabled for allocating PoE
power based on the link-partner’s capabilities via LLDP
• Configured Type: If configured, shows the user-specified
identifier for the port. If not configured, the field is empty.
• Value: The maximum amount of PoE power allocated for that
port (expressed in watts).
• Power Class: Shows the power class of the PD detected on the
indicated port. Classes include:
0: Depends on cable type and PoE architecture
1: 0.44w to 3.84w
2: 3.84w to 6.49w
3: 6.49w to 12.95w
4: reserved: can be power value beyond the class 3 limit.
Depends on cable type and PoE architecture
• MPS Absent Cnt: This value 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.” Refer to “PoE
Terminology” on page 11-4.)
• 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.
