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.) Or, the port just may have been
configured as disabled through software.
Action

◆
cord and the wall outlet.

◆

panel.
Verify that the proper cable types is used and its
◆
length does not exceed specified limits.
