◆ An MLAG domain may have many MLAGs.
◆ An MLAG can belong to one and only one MLAG domain.
◆ The associated MLAG domain may be nonexistent, which causes the MLAG to
be inactive locally.
◆ There can be one and only one MLAG member for each MLAG on an MLAG
device.
◆ The MLAG member can be a normal port or a static trunk.
◆ An MLAG member is active if the MLAG ID is set and the associated MLAG
domain is active.
