Power Over Ethernet (PoE) Operation
Viewing PoE Configuration and Status
Displaying PoE Status on All Ports
Syntax
:
show power-over-ethernet brief
Displays the following port power status:
• Port:
Lists all PoE-capable ports on the switch.
• Power Enable:
Shows
Yes
for ports enabled to support PoE (the
default) and
No
for ports on which PoE is disabled .
• LLDP Detect:
Displays if the port is enabled or disabled for
allocating PoE power based on the link-partner’s capabilities
via LLDP
( enabled , disabled ).
Not all PoE devices support
LLDP, so PoE information is ignored by default.
• Priority:
Lists the power priority (
Low
,
High
, and
Critical
)
configured on ports enabled for PoE. (For more on this topic,
refer to the power command description under “Configuring
PoE Operation” on page 11-14.)
• Alloc by :
Displays how PoE is allocated
( usage, class, value)
• PoE Value:
The maximum amount of PoE power allocated for
that port (expressed in watts). Default: 17W
• Configured Type:
If configured, shows the user-specified
identifier for the port. If not configured, the field is empty.
Refer to “Configuring Optional PoE Port Identifiers” on
page 11-22.
• Detection Status:
– Searching:
The port is trying to detect a PD connection.
–
Delivering:
The port is delivering power to a PD.
–
Disabled:
On the indicated port, either PoE support is
disabled or PoE power is enabled but the PoE module does
not have enough power available to supply the port’s power
needs.
–
Fault:
The switch detects a problem with the connected PD .
• Power Class:
Shows the 802.3af power class of the PD detected
on the indicated port. Classes include:
0 : 0.44w to 12.95w
1
: 0.44w to 3.84w
2 : 3.84w to 6.49w
3 : 6.49w to 12.95w
4:
reserved
• Other fault: The switch has detected an internal fault that
prevents it from supplying power on that port.
