"Configured hello..." "We are..." "Current root..." "Topology flag." "Number of..." "Timers" 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 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. 1424 | Spanning Tree Protocol (STP)
