DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
558
Parameters
57-4 spanning-tree tx-hold-count
This command is used to limit the maximum BPDU transmission rate for every port. Use the no form of this command
to return the setting to default setting.
spanning-tree transmit-hold-count
TX-HOLD-COUNT
no spanning-tree transmit-hold-count
Parameters
hello-time
SECONDS
Specifies the time interval to send one BPDU at the Designated Port. The default
setting is 2 seconds. The range is 1 to 2 seconds.
Note:
This timer cannot be configured in MSTP mode.
forward-time
SECONDS
Specifies the maximum time (in seconds) the device will wait before changing states
(i.e., from the listening to learning to forwarding). The default setting is 15 seconds.
The range is 4 to 30 seconds.
max-age
SECONDS
Specifies the maximum aging time (in seconds) of the BPDU message. The default
setting is 20 seconds.The range is 6 to 40 seconds.
Default
The default value of
hello-time
is 2.
The default value of
forward-time
is 15.
The default value of
max-age
is 20.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 8
Usage Guideline
There are some constraints on the relationship of the three timers.
Please refer to the following formulas :
• 2 × (Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age
• Bridge_Max_Age >= 2 × (Bridge_Hell 1.0 seconds)
Parameters cannot be applied if the equation is not satisfied.
Example
This example shows how to configure the STP timer.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#spanning-tree hello-time 1
Success
DXS-3600-32S(config)#spanning-tree forward-time 16
Success
DXS-3600-32S(config)#spanning-tree max-age 21
Success
DXS-3600-32S(config)#
TX-HOLD-COUNT
Specifies the value to restrict the numbers of BPDU transmitted on a port in the
period of a Hello Time. The range is 1 to 10.
Default
The default value is 6.
Command Mode
Global Configuration Mode.
