Usage Guidelines

Usage Scenario

By default, a PoE interface works in standard hierarchical power supply mode. If PoE interfaces provide power to non-standard PDs in standard hierarchical power supply mode, these PDs cannot initiate power requests using LLDP or CDP and can only obtain a low power. As a result, these PDs cannot work normally. To address this issue, run the poe single-class enable command to configure the single-class power supply mode for PoE interfaces. These non-standard PDs can then initiate power requests and obtain the standard power supply to work normally.

Precautions

If a standard PD is connected to the interface, this PD may be unable to work normally after the poe single-class enable command is run.
On the S5720-16X-PWH-LI-AC, S5720-28X-PWH-LI-AC, S5720I-SI, S5735-L, S5735S-L, S5735S-L-M, S5735-S, S5735-S-I, S5730-HI, S5730-SI, S5730S-EI, S5731-H, S5731-S, S5731S-S, S5732-H, and S6720-SI, the poe af-inrush enable and poe single-class enable commands are mutually exclusive and cannot be configured on the same interface.

Example

# Configure the single-class power supply mode for GE0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] poe single-class enable
