Port Monitor-Link Group - 3Com 5500-EI PWR Reference Manual

In Monitor Link, a monitor link group member can be a single port, a static link aggregation group, but
not a dynamic link aggregation group. The uplink port of a monitor link group can also be a smart link
group.
Do not use this command on member ports of a link aggregation group or a smart link group.
A port or a link aggregation group cannot serve as a member port for two smart link groups. On the
other hand, a port or a link aggregation group cannot serve as a member for a smart link group and a
monitor link group at the same time. However, a smart link group can serve as the uplink member port
of a monitor link group.
