A trunk can consist of either 10/100 ports or
10/100/1000 ports (fixed ports 25 and 26). It is not
possible to have a trunk containing a mixture of

If a port is a member of an aggregated link (or trunk),

have the same settings, and you can configure these
by clicking the AL link on the Port Configuration
