LABEL DESCRIPTION
MSTID This field displays the MSTI ID.
BridgeID This field displays the unique identifier for this bridge, consisting of bridge priority
plus MAC address.
TimeSinceTopoChange This field displays the time since the spanning tree was last reconfigured.
TopoChangeCount This field displays the number of times the spanning tree has been reconfigured.
TopoChange This field indicates whether or not the current topology is stable.
0: The current topology is stable.
1: The current topology is changing.
DesignatedRoot This field displays the unique identifier for the root bridge, consisting of bridge
priority plus MAC address.
RootPathCost This field displays the path cost from the root port on this OLT to the root switch.
RootPort This field displays the priority and number of the port on the OLT through which
this OLT must communicate with the root of the Spanning Tree.
RootMaxAge This field displays the maximum time (in seconds) the root switch can wait without
receiving a configuration message before attempting to reconfigure.
RootHelloTime This field displays the time interval (in seconds) at which the root switch transmits
a configuration message.
RootForwardDelay This field displays the time (in seconds) the root switch will wait before changing
states (that is, listening to learning to forwarding).
BridgeMaxAge This field displays the maximum time (in seconds) the OLT can wait without
receiving a configuration message before attempting to reconfigure.
BridgeHelloTime This field displays the time interval (in seconds) at which the OLT transmits a
configuration message.
BridgeForwardDelay This field displays the time (in seconds) the OLT will wait before changing states
(that is, listening to learning to forwarding).
ForceVersion This field indicates whether BPDUs are RSTP (a value less than 3) or MSTP (a value
greater than or equal to 3).
TransmissionLimit This field displays the maximum number of BPDUs that can be transmitted in the
interval specified by BridgeHelloTime.
