(Optional) Configuring a 10GE Optical Port as a Proxy for a MultiGE Electrical Port to Perform LLDP Negotiation
Context
Usage Scenario
- One end of the RJ45 cable in a hybrid optical/electrical cable is connected to a MultiGE electrical port of a switch, and the other end is connected to the RJ45 power receiving port of an AP. The RJ45 cable is used only for the switch to provide PoE power supply for the AP and does not transmit data.
One end of the optical fiber in a hybrid optical/electrical cable is connected to a 10GE optical port on a switch, and the other end is connected to an uplink 10GE optical port on an AP. The optical fiber is used for data transmission between the switch and AP.
Since the MultiGE electrical port connected to a hybrid optical/electrical cable stays in the down state, to use LLDP to negotiate the power supply capability, you must run the poe lldp-proxy command to configure the 10GE optical port on the switch connected to the hybrid optical/electrical cable as a proxy for the MultiGE electrical port to perform LLDP negotiation.
Precautions
- LLDP must be enabled on the 10GE optical port connected to a hybrid optical/electrical cable. This function is enabled by default.
- If an AP requires PoE++ power supply, run the poe legacy enable command on the 10GE optical port connected to a hybrid optical/electrical cable to enable compatibility check.
Only the S5732-H48XUM2CC supports this function.
Procedure
- Run system-view
The system view is displayed.
- Run interface xgigabitethernet interface-number
The 10GE interface view is displayed.
- Run poe lldp-proxy interface multige interface-number
The 10GE optical port is configured as a proxy for the specified MultiGE electrical port to perform LLDP negotiation.
By default, a 10GE optical port does not act as a proxy for a MultiGE electrical port to perform LLDP negotiation.
