Setting up an M-LAG system

Multichassis Link Aggregation (M-LAG) virtualizes two physical devices into one system through
multichassis link aggregation to provide device-class high availability and load sharing.
Compared to IRF, M-LAG offers higher network reliability and shorter service interruption during
upgrade.
You cannot configure IRF and M-LAG on the same network.
IMPORTANT:
The device supports both the M-LAG set and DRNI set of command keywords in the CLI by default.
The two sets of commands are consistent in the service configuration methods, functions, and
output, with only differences in the command keywords. For the differences in the command
keywords, see M-LAG configuration in Layer 2—LAN Switching Configuration Guide of H3C S6805
& S6825 & S6850 & S9850 Switch Series Configuration Guides-Release 671x.
