State Ports can be in one of the following STP states, depending on its configuration and the status
of the STP topology convergence:
Blocking—The port discards user traffic and receives, but does not send, BPDUs.
During the election process, all ports are in the blocking state. The port is blocked to pre-
vent network loops.
Forwarding—The port sends and receives user traffic.
Disabled—The port is administratively disabled and is not part of the spanning tree. This
is the default selection.
Cost The path cost from the port to the root bridge.
Hello Time The amount of time the root bridge waits between sending hello BPDUs.
Point-to-point MAC A True/False value. True indicates a switched link with only two nodes, and False indicates a
shared network segment with more than two nodes. The value may be automatically
computed or explicitly configured.
Edge When enabled, allows the interface to become an edge port if it does not receive any BPDUs
within a given amount of time.
