Context config>redundancy>multi-chassis>peer>mc-lag
Description This command defines a LAG which is forming a redundant-pair for MC-LAG with a LAG configured on
the given peer. The same LAG group can be defined only in the scope of 1 peer. In order MC-LAG to
become operational, all parameters (lacp-key, system-id, system-priority) must be configured the same on
both nodes of the same redundant pair.
The partner system (the system connected to all links forming MC-LAG) will consider all ports using the
same lacp-key, system-id, system-priority as the part of the same LAG. In order to achieve this in MC
operation, both redundant-pair nodes have to be configured with the same values. In case of the mismatch,
MC-LAG is kept in oper-down status.
Note that the correct CLI command to enable MC LAG for a LAG in standby-signaling power-off mode is
lag lag-id [remote-lag remote-lag-id]. In the CLI help output, the first three forms are used to enable MC
LAG for a LAG in LACP mode. MC LAG is disabled (regardless of the mode) for a given LAG with no lag
lag-id.
Default
none
Parameters
lag-id — The LAG identifier, expressed as a decimal integer. Specifying the lag-id allows the mismatch
between lag-id on redundant-pair. If no lag-id is specified it is assumed that neighbor system uses the
same lag-id as a part of the given MC-LAG. If no matching MC-LAG group can be found between
neighbor systems, the individual LAGs will operate as usual (no MC-LAG operation is established.).
Values
lacp-key admin-key — Specifies a 16 bit key that needs to be configured in the same manner on both sides
of the MC-LAG in order for the MC-LAG to come up.
Values
system-id system-id — Specifies a 6 byte value expressed in the same notation as MAC address
Values
remote-lag lag-id — Specifies the LAG ID on the remote system.
Values
system-priority system-priority — Specifies the system priority to be used in the context of the MC-LAG.
The partner system will consider all ports using the same lacp-key, system-id, and system-priority as
part of the same LAG.
