Bridge Max Age - Specifies the bridge max age for the Common and Internal Spanning tree (CST). The
value lies between 6 and 40, with the value being less than or equal to "2 * (Bridge Forward Delay - 1)"
and greater than or equal to "2 * (Bridge Hello Time + 1)". The default value is 20.
Bridge Hello Time - Specifies the bridge hello time for the Common and Internal Spanning tree (CST),
with the value being less than or equal to "(Bridge Max Age / 2) - 1". The default hello time value is 2.
Bridge Forward Delay- Specifies the time spent in "Listening and Learning" mode before forwarding
packets. Bridge Forward Delay must be greater or equal to "(Bridge Max Age / 2) + 1". The time range is
from 4 seconds to 30 seconds. The default value is 15.
Spanning Tree Maximum Hops- Configure the maximum number of hops for the Spanning tree.
Non-Configurable Data
Bridge identifier - The bridge identifier for the CST. It is made up using the bridge priority and the base
MAC address of the bridge.
Time since topology change - The time in seconds since the topology of the CST last changed.
Topology change count - Number of times topology has changed for the CST.
Topology change - The value of the topology change parameter for the switch indicating if a topology
change is in progress on any port assigned to the CST. It takes a value if True or False.
Designated root - The bridge identifier of the root bridge. It is made up from the bridge priority and the
base MAC address of the bridge.
Root Path Cost - Path Cost to the Designated Root for the CST.
Root Port - Port to access the Designated Root for the CST.
Max Age - Path Cost to the Designated Root for the CST.
Forward Delay - Derived value of the Root Port Bridge Forward Delay parameter.
Hold Time - Minimum time between transmission of Configuration BPDUs.
CST Regional Root - Priority and base MAC address of the CST Regional Root.
CST Path Cost - Path Cost to the CST tree Regional Root.
