Mac Address of the CIST regional root bridge.
CIST INTERNAL ROOT PATH COST:
Root path cost value from the point of view of the bridges inside the IST.
CIST CURRENT MAX AGE:
Max Age of the CIST Root bridge.
CIST CURRENT FORWARD DELAY:
Forward Delay of the CIST Root bridge.
TIME SINCE LAST TOPOLOGY CHANGE(SECs):
Time Since Last Topology Change is the elapsed time in unit of seconds
for a bunch of “Topology Change and(or) Topology Change Notification
receiving” to occur. When new series of Topology Changes occur again,
this counter will be reset to 0.
TOPOLOGY CHANGE COUNT(SECs):
The per spanning tree instanceTopology Change Count expresses the
time spent in unit of seconds since the beginning of the Spanning Tree
Topology Change to the end of the STP convergence. Once there is no
topology change occurring and no more topology change notification
received, the Topology Change count will be reset to 0.
Parameter description:
Port No:
1- 8
Status:
Fig. 3-161 Port Status
The forwarding status.Same definition as of the RSTP specification
Possible values are “FORWARDING” , “LEARNING” , “DISCARDING”
Status:
The role that a port plays in the spanning tree topology. Possible values
are “dsbl”(disable port) , ”alt”(alternate port) , “bkup”(backup port) ,
“ROOT”(root port) , “DSGN”(designated port) , “MSTR”(master port). The
last 3 are possible port roles for a port to transit to FORWARDING state
Path Cost:
Display currently resolved port path cost value for each port in a
