Monitoring STP Port Status
308 Avidia System Configuration and Management User Manual
Information Description
Bridge Port The logical bridge session port number. The system automatically assigns
this number when you configure a bridging session.
Priority The configured Spanning Tree Protocol priority for the session port.
Port State The current Spanning Tree Protocol state of the session port, either
Forwarding, Blocked, or Learning.
Path Cost The configured Spanning Tree Protocol path cost for the session port. The
Path Cost indicates the efficiency of the session.
Designated Root An eight-byte octet that displays the port priority in hexidecimal (first two
bytes) followed by the MAC address of the bridge that is designated as the
root, or base, of the Spanning Tree topology.
Designated Cost The cost of the path from the bridge port to the designated root. The range
is from 1 to 65535, with 1 indicating the lowest cost.
Designated Bridge An eight-byte octet that displays the port priority in hexidecimal (first two
bytes) followed by the MAC address of the bridge that is chosen by the STP
to forward traffic to the root.
Designated Port The bridge port that is chosen by the STP to forward traffic to the root.
Forward Transitions The number of times the bridge port state has changed from Learning to
Forwarding. The STP changes the bridge state in response to learned
topology changes.
