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