designated
port); or is an
alternate
or
backup
port that may provide
connectivity if other bridges, bridge ports, or LANs fail or are removed.
◆
State
- Displays the current state of this port within the Spanning Tree:
■
Blocking
- Port receives STA configuration messages, but does not
forward packets.
■
Learning
- Port has transmitted configuration messages for an
interval set by the Forward Delay parameter without receiving
contradictory information. Port address table is cleared, and the
port begins learning addresses.
■
Forwarding
- Port forwards packets, and continues learning
addresses.
◆
Path Cost
- The contribution of this port to the path cost of paths
towards the spanning tree root which include this port. This will either
be a value computed from the Auto setting, or any explicitly configured
value.
◆
Edge
- The current RSTP port (operational) Edge Flag. An Edge Port is
a switch port to which no bridges are attached. The flag may be
automatically computed or explicitly configured. Each Edge Port
transitions directly to the Forwarding Port State, since there is no
possibility of it participating in a loop.
◆
Point2Point
- Indicates a connection to exactly one other bridge. The
flag may be automatically computed or explicitly configured. The point-
to-point properties of a port affect how fast it can transition RSTP
states.
◆
Uptime
- The time since the bridge port was last initialized.
