CAUTION:

In an M-LAG system, all management Ethernet ports on the primary and secondary devices are
available for use. From the perspective of the network management system, the two devices in
the M-LAG system are independent and you must log in and manage them separately.
•
To prevent network failures caused by M-LAG system splitting, configure HA after the M-LAG
system is set up. For more information, see
