8-190 show mstp cist Rapier Switch Software Reference
Software Release 2.7.3
C613-03098-00 REV A
Example To display the current CIST information, use the command:
show mstp cist
Related Commands disable mstp
enable mstp
set mstp cist
set mstp cist port
enable mstp cist port
disable mstp cist port
Root Port The port number of the root port for the switch. This
parameter is not valid if the switch is the root bridge.
In this situation the output will be shown as N/A.
External Root Path Cost The path cost to the region containing the CIST root
from this region.
Internal Root Path Cost The path cost to the CIST Regional Root.
Max Age The maximum age of received bridge protocol
message (BPDU) information before it is discarded.
Hello Time The time, in seconds, between transmissions of
spanning tree configuration information (BPDUs)
Forward Delay The maximum time taken to transition from the
discarding state to the learning state, and from the
learning state to the forwarding state.
Max Hops Specifies the maximum hop count within an MST
region for CIST information transmitted from this
switch.
Bridge Max Age The value of the Max Age parameter when the switch
is either the root or is attempting to become the root.
This parameter is set by the maxage parameter in
the set mstp command.
Bridge Hello Time The value of the Hello Time parameter when the
switch is the root or is attempting to become the
root. This parameter is set by the hellotime
parameter in the set mstp command.
Bridge Forward Delay The value of the Forward Delay parameter when this
switch is the root or is attempting to become the
root. This parameter is set by the forwarddelay
parameter in the set mstp command.
Bridge Max Hops The value of the Max Hops parameter when the
switch is either the root or is attempting to become
the root. This parameter is set by the maxhops
parameter in the set mstp command.
Transmission Limit The number of BPDUs that may be transmitted in the
interval specified by the hellotime parameter. The
value of this fixed parameter is 3.
Time Since Topology Change The count in seconds of the time elapsed since the
last topology changed.
Topology Change Count The number of times the topology has changed since
the bridge was powered or initialised.
Topology Change Indicates whether the topology is in the middle of
changing.
