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.
The same lacp-key, system-id, and system-priority must be configured on both nodes of the
redundant pair in order to MC-LAG to become operational. 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 operationally down.
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 1 — 200
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 1 — 65535
system-id system-id — Specifies a 6 byte value expressed in the same notation as MAC address
Values xx:xx:xx:xx:xx:xx - xx [00..FF]
remote-lag lag-id — Specifies the LAG ID on the remote system.
Values 1 — 200
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.
Values 1 — 65535
