Configuring Spanning-Tree Bridge Forward-Time
The forward time is the delay time, in seconds, that all bridges use for forward
delay when this bridge is acting as the root. By default, the bridge forward delay
time is 4 seconds. Use the bridge forward-time command to set the bridge
forward delay time. Enter an integer from 4 to 30.
To set the bridge forward time to 9, enter:
(config)# bridge forward-time 9
To restore the default delay time of 4, enter:
(config)# no bridge forward-time
Configuring Spanning-Tree Bridge Hello-Time
The hello time is the time, in seconds, that all bridges wait before sending a hello
packet (when the bridge acts as the root). By default, the bridge hello time interval
is 1 second. Use the bridge hello-time command to set the bridge hello time
interval. Enter an integer from 1 to 10.
To set the bridge hello time to 9, enter:
(config)# bridge hello-time 9
To restore the default hello time interval of 1, enter:
(config)# no bridge hello-time
Configuring Spanning-Tree Bridge Max-Age
The maximum age is the time, in seconds, that protocol information received on
a port is stored by the CSS (when a bridge acts as the root). By default, the bridge
spanning-tree maximum age is 6 seconds. Use the bridge max-age command to
set the bridge spanning-tree maximum age. Enter an integer from 6 to 40.
Note Ensure the bridge maximum age is greater than or equal to 2 times (bridge
hello-time + 1 second) and less than or equal to 2 times (bridge forward-time - 1
second).
