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:

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.
Configured Hello Time
Synopsis:
0 to 65535
The configured Hello time from the Bridge RSTP Parameters menu.
