Multiple Spanning Tree Protocol (MSTP)
block 200000
D e s c r i p t i o n
Indicates whether MSTP is enabled or disabled on the switch.
Displays the supported IEEE standard..
The bridge priority which is part of the bridge identifier.
The count in seconds since tcWhile timer (Topology-Change
State Machine timer, specified in IEEE 802.1s, 13.21) for any
Port was non-zero.
The number of topology changes detected for all the MSTIs.
The CIST Regional Root Identifier. The Bridge Identifier of the
current CIST Regional Root.
The port in the switch from which the traffic flows to the CIST
root.
The CIST Path Cost. The CIST path cost from the transmitting
Bridge to the CIST Regional Root.
The maximum age in seconds of received protocol information
before it is discarded.
The time interval in seconds between the transmissions of
Configuration BPDUs by a Bridge that is attempting to become
the Root or is the Root.
The forward time for all MST instances. The forward delay is
the number of seconds a port waits before changing from its
spanning-tree learning and listening states to the forwarding
state.
The value of the Max Age parameter in seconds when the
Bridge is the Root or is attempting to become the Root.
The value of the Hello Time parameter in seconds when the
Bridge is the Root or is attempting to become the Root.
This parameter is the time interval between transmissions of
Topology Change Notification BPDUs towards the Root, when
the Bridge is attempting to notify the Designated Bridge on the
LAN to which its Root Port is attached of a topology change.
The value of the Forward Delay parameter in seconds when
the Bridge is the Root or is attempting to become the Root.
This value is used by the Protocol Migration Machine to limit
transition between the port's states.
