Disabled State
A port in the disabled state does not participate in frame
forwarding or STP. A port in the disabled state is virtually
non-operational.
A disabled port does the following:
•
Discards packets received from the network segment to
which it is attached.
•
Discards packets sent from another port on the switch
for forwarding.
•
Does not add addresses to its forwarding database.
•
Receives BPDUs, but does not direct them to the
system CPU.
•
Does not receive BPDUs for transmission from the
system CPU.
•
Receives and responds to network management
messages.
