When a server is dual-homed to CE switches through M-LAG, the server cannot transmit traffic to one of the CE switches

The cause is that the LACP M-LAG system priorities and IDs of two CEs in the M-LAG are inconsistent. Eth-Trunks on both switches configured with M-LAG must use the same LACP M-LAG system priority and ID.
- In V100R006C00 and earlier versions, run the lacp m-lag priority priority command on the Eth-Trunks of both switches configured with M-LAG to set the same LACP M-LAG system priority and run the lacp m-lag system-id mac-address command to set the same LACP M-LAG system ID.
- In V200R001C00 and later versions, the slave switch in the M-LAG automatically synchronizes the LACP M-LAG system priority and ID of the master switch through the peer-link.
