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. Note that this STP port state should not be confused with the port’s
administrative state.
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 bridge for forwarding.
• Does not add addresses to its forwarding database.
• Neither receives nor transmits BPDUs.
The following illustration shows the actions that occur when a port is in the disabled state.
