Description
Lists the bridge priority and the MAC address for this STP
bridge.
Displays the settings for hello time, max age, and forward
delay.
States whether BPDU Filter is enabled/disabled globally.
States whether this bridge is the root bridge for the STG.
Lists the bridge priority and MAC address for the root
bridge.
States whether the topology flag and the detected flag were
set.
Displays the number of topology changes, the time of the
last topology change, and on what interface the topology
change occurred.
Lists the values for the following bridge timers:
hold time, topology change, hello time, max age, and
forward delay.
