The dldp compatible-mode local-mac command configures the switch to send DLDP packets containing source MAC addresses in the DLDP compatible mode.
The undo dldp compatible-mode local-mac command restores the source MAC addresses of the DLDP packets to the default MAC address.
By default, the MAC address of a DLDP packet is the system MAC address.

Usage Scenario
You can run dldp compatible-mode local-mac command to configure the source MAC addresses for DLDP packets sent in DLDP compatible mode. This prevents the DLDP flapping due to discovery of multiple neighbors when the device needs to work with the following Huawei switches:
S8500
S7800
S6500
S5600 series switches
S5100-EI
S3900 series switches
S3500 series switches
S3100 series switches
Prerequisites
The DLDP compatible mode has been enabled using the dldp compatible-mode enable command.
Precautions
When the configuration is complete, the newly configured MAC address is used as the source MAC addresses of the sent DLDP packets.
# Set the source MAC address of the DLDP packets sent by interface GE0/0/1 in DLDP compatible mode to 00e0-0000-9211.
