(Optional) Configure the Single-Class Power Supply Mode for a PoE Interface
Context
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, set the hierarchical power supply mode of PoE interfaces to single-class power supply mode. These non-standard PDs can then initiate power requests and obtain the standard power supply to work normally.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run poe single-class enable
The hierarchical power supply mode of the PoE interface is set to single-class power supply mode.
