cost is 0. The identity of the designated bridge is shown in the
Designated Bridge field.
The current values for the following timers, if active:
• Message age – The number of seconds this port has been
waiting for a hello message from the root bridge.
• Forward delay – The number of seconds that have passed since
the last topology change and consequent reconvergence.
• Hold time – The number of seconds that have elapsed since
