ACTIVATE SWITCH PORT

Parameter
port Specifies a port. You can activate more than one port at
a time.
Description
This command prompts a port that is using Auto-Negotiation to
renegotiate its settings with its end node. The command can be helpful if
you believe that a port and an end node have not successfully negotiated
their settings.
