DESCRIPTION
This is the time (in seconds) the root bridge will wait before changing states
(that is, listening to learning or learning to forwarding) on the root port. Each
change in states requires the forward delay time before the change.
This is the maximum time (in seconds) the root bridge can wait without
receiving a configuration message before attempting to reconfigure.
This is the time interval (in seconds) at which the root switch transmits a
configuration message. The root bridge determines the Hello Time, Max Age
and Forward Delay.
This is the time (in seconds) the root switch will wait before changing states
(that is, listening to learning to forwarding).
This is the version of spanning tree protocol the device is using (MSTP or
RSTP). The system will send BPDUs of the specified spanning tree version.
This is the number of BPDUs that are allowed to be sent before pausing for 1
second.
This field displays the ID of the root switch in a region.
This field displays path cost to the internal root bridge.
These are the MSC's subtending and uplink Ethernet ports. Click a link to see
detailed MSTP CIST statistics for that port.
This field displays whether a port is active or not.
This field displays the time the port is running.
This field displays the STP status on this port.
This field displays port ID.
This field displays true when the link is up or false if the link is not up.
This field displays whether the BPDU received was transmitted by a bridge in
the same region.
