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:
• In Release 6635 and earlier, M-LAG is called DRNI and uses the DRNI set of command
keywords in the CLI.
• In Release 6710 and later, 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 H3C S9820-8C &
S9820-8C-SAN Ethernet Switches Layer 2—LAN Switching Configuration Guide.
