This table displays the following information:
Parameter Description
Bridge Status Synopsis: { , Designated Bridge, Not Designated For Any LAN, Root Bridge }
Spanning Tree status of the bridge. The status may be root or designated. This field may
show text saying not designated for any LAN if the bridge is not designated for any of its
ports.
Bridge ID Synopsis: $$ / ##-##-##-##-##-## where $$ is 0 to 65535, ## is 0 to FF
Bridge Identifier of this bridge.
Root ID Synopsis: $$ / ##-##-##-##-##-## where $$ is 0 to 65535, ## is 0 to FF
Bridge Identifier of the root bridge.
Root Port Synopsis: 1/1 to 8/2 or { <empty string> }
If the bridge is designated, this is the port that provides connectivity towards the root bridge
of the network.
Root Path Cost Synopsis: 0 to 4294967295
Total cost of the path to the root bridge composed of the sum of the costs of each link in the
path. If custom costs have not been configured. 1Gbps ports will contribute 4, 100 Mbps
ports will contribute 19 and 10 Mbps ports will contribute a cost of 100 to this figure.
For the CIST instance of MSTP, this is an external root path cost, which is the cost of the
path from the IST root (i.e. regional root) bridge to the CST root (i.e. network "global" root)
bridge.
Total Topology Changes Synopsis: 0 to 65535
A count of topology changes in the network, as detected on this bridge through link failures
or as signaled from other bridges. Excessively high or rapidly increasing counts signal
network problems.
Time since Last TC Synopsis: DDDD days, HH:MM:SS
The time since the last time a topology change was detected by the bridge.
