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:
T1500-28PCT(config)# spanning-tree timer forward-time
16
hello-time

spanning-tree hold-count
Description
The
spanning-tree hold-count
command is used to configure the maximum
number of BPDU packets transmitted per Hello Time interval. To return to the
default configurations, please use
no spanning-tree hold-count
command.
Syntax

value
no spanning-tree hold-count
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.
