Configuration prerequisites
Enable PoE for PoE interfaces.
Configuration procedure
Follow these steps to configure PoE interface power management:
To do… Use the command… Remarks
Enter system view system-view —
Configure PoE interface power
management priority policy
poe pd-policy priority
Required
Not configured by default.
Enter PoE interface view
interface interface-type
interface-number
—
Configure the power supply
priority for a PoE interface
poe priority { critical | high | low }
Optional
low by default.
Configuring the PoE monitoring function
With the PoE monitoring function enabled, the system monitors the parameter values related to PoE
power supply, PSE, PD, and device temperature in real time. When a specific value exceeds the limited
range, the system automatically takes some measures to protect itself.
Configuring PSE power monitoring
When the PSE power exceeds or drops below the specified threshold, the system sends trap messages.
Follow these steps to configure a power alarm threshold for the PSE:
To do… Use the command… Remarks
Enter system view system-view —
Configure a power alarm threshold
for the PSE
poe utilization-threshold
utilization-threshold-value
Optional
80% by default.
Monitoring PD
When a PSE starts or ends power supply to a PD, the system sends a trap message.
Configuring PoE interface through PoE profile
You can configure a PoE interface either at the CLI or by using a PoE profile and applying the PoE profile
to the specified PoE interfaces.
To configure a single PoE interface, configure it at the CLI. To configure PoE interfaces in batches, use a
PoE profile.
