Parameter
forward-time —— Forward Delay, which is the time for the port to transit its
state after the network topology is changed. Forward Delay ranges from 4 to 30
in seconds and it is 15 by default. Otherwise, 2 * (Forward Delay - 1) >= Max
Age.
hello-time ——Hello Time, which is the interval to send BPDU packets, and
used to test the links. Hello Time ranges from 1 to 10 in seconds and it is 2 by
default. Otherwise, 2 * (Hello Time + 1) <= Max Age.
max-age —— The maximum time the switch can wait without receiving a
BPDU before attempting to reconfigure, ranging from 6 to 40 in seconds. By
default, it is 20.
Command Mode

Example
Configure forward-time, hello-time and max-age for Spanning Tree as 16
seconds, 3 seconds and 22 seconds respectively:
TL-SG3424(config)# spanning-tree timer forward-time 16 hello-time 3
max-age 22

Parameter
value —— The maximum number of BPDU packets transmitted per Hello Time
interval, ranging from 1 to 20 in pps. By default, it is 5.
