Check the port
configuration.
A port on your switch may not be operating as you expect
because it has been put into a “blocking” state by
Spanning Tree, GVRP (automatic VLANs), or LACP
(automatic trunking). (Note that the normal operation of
the Spanning Tree, GVRP, and LACP features may put the
port in a blocking state.) Alternatively, the port just may
have been configured as disabled through software.
