Designated Root Port Port through which the root bridge can be reached.
Designated Root Priority Priority of the designated root bridge.
Designated Root Cost Total path cost to reach the root.
Root Max Age Amount of time (in seconds) a BPDU packet should be considered
valid.
Root Hello Time Interval (in seconds) at which the root device sends BPDU (Bridge
Protocol Data Unit) packets.
Root Forward Delay Amount of time (in seconds) the root device spends in listening or
learning mode.
Bridge ID MAC Address Unique bridge MAC address, recognized by all bridges in the network.

page 6-27.
Topology Change Count Number of times topology has changed on the bridge.
Time Since Top Change Amount of time (in days, hours, minutes and seconds) since the last
topology change.
Max Hops Maximum number of hops information for a particular Spanning Tree
instance may traverse (via relay of BPDUs within the applicable MST
region) before being discarded. This is a default value, or is assigned
using the set spantree mashops command. For details, refer to “set
spantree maxhops” on page 6-35.
