to this port, the manual setting for Edge Port will be overridden, and the
port will instead function as a point-to-point connection.
• P2P Port – Shows if this port is functioning as a Point-to-Point
connection to exactly one other bridge.
The switch can automatically determine if the interface is attached to a
point-to-point link or to shared media. If shared media is detected, the
switch will assume that it is connected to two or more bridges.
• Protocol – Shows the spanning tree protocol functioning on this port,
either RSTP or STP (that is, STP-compatible mode).
• Port Role – Roles are assigned according to whether the port is part of
the active topology connecting the bridge to the root bridge (i.e., root
port), connecting a LAN through the bridge to the root bridge (i.e.,
designated port); or is an alternate or backup port that may provide
connectivity if other bridges, bridge ports, or LANs fail or are removed.
The role is set to disabled (i.e.,
disabled port) if a port has no role within
the spanning tree.
• Port State – Displays current state of this port within the Spanning Tree:
- Discarding – 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.
- Disabled – Spanning tree is enabled on this port, but it has no role
within the spanning tree.
- Non-STP – Spanning tree is not enabled on this port.
