bridge, the “Designated Root” will show this switch’s bridge ID.
Designated Priority:
Show the current root bridge priority.
Root Port:
Show port number connected to root bridge with the lowest path cost.
Root Path Cost:
Show the path cost between the root port and the designated port of the
root bridge.
Current Max. Age:
Show the current root bridge maximum age time. Maximum age time is
used to monitor if STP topology needs to change. When a bridge does
not receive a hello message from root bridge until the maximum age time
is counted down to 0, the bridge will treat the root bridge malfunctioned
and issue a Topology Change Notification (TCN) BPDU to all other
bridges.
All bridges in the LAN will re-learn and determine which the root bridge is.
Maximum Age time is assigned by root bridge in unit of seconds. Default
is 20 seconds.
Current Forward Delay:
Show the current root bridge forward delay time. The value of Forward
Delay time is set by root. The Forward Delay time is defined as the time
spent from Listening state moved to Learning state or from Learning
state moved to Forwarding state of a port in bridge.
Hello Time:
Show the current hello time of the root bridge. Hello time is a time
interval specified by root bridge, used to request all other bridges
periodically sending hello message every “hello time” seconds to the
bridge attached to its designated port.
STP Topology Change Count:
STP Topology 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 the STP change is converged, the Topology
Change count will be reset to 0. The figures showing in the screen may
not be the exact time it spent but very close to, because the time is
eclipsing.
Time Since Last Topology Change:
Time Since Last Topology Change is the accumulated time in unit of
seconds the STP has been since the last STP Topology Change was
made. When Topology Change is initiated again, this counter will be
reset to 0. And it will also count again once STP topology Change is
completed.
