♦ Port Displays the port (on the switch) that offers the least path cost from the bridge to the root bridge. In the event of
a network loop, data packets will pass through the port specified here.
♦ Priority Displays the priority number of the root bridge in the Spanning Tree. The value is used in conjunction with
the bridge MAC address to set the bridge ID, which in turn is used in determining the root bridge of a multi-bridged
network. The root bridge is responsible for processing data packets when network loops occur. The smaller the number
set, the higher the bridge priority is. The higher the bridge priority, the more chances the bridge has of becoming the root
bridge. A bridge priority ranges from 0 to 65535, with 0 being the highest priority.
♦ Switch Priority This is a read-only object that containing values from 0 to 65535. This value can be set in the
Bridge Priority field and is the priority number of the bridge. The value is used in conjunction with the bridge MAC
address to set the bridge ID, which in turn is used when determining the root bridge of a multi-bridged network. The
root bridge is responsible for processing data packets when network loops occur. The smaller the number set, the higher
the bridge priority is. The higher the bridge priority, the more chance the bridge has of becoming the root bridge. Zero is
the highest priority.
♦ Hello Time Displays the interval between two transmissions of BPDU packets sent by the root bridge to tell all
other switches that it is indeed the root bridge.
♦ Max Age Read-only object indicates the maximum age of STP information learned from the network (on any port)
before it is discarded.
♦ Forward Delay Displays the time any port on the Switch spends in the listening state while moving from the
blocking state to the forwarding state.
