Quidway S3500 Series Ethernet Switches Chapter 1 MSTP Configuration Commands
Huawei Technologies Proprietary
1-35
Only if the above-mentioned formulas are equal can the MSTP normally operate on the
entire network, otherwise, the network may flap frequently. You are recommended to
use the stp root primary command to specify the diameter of the switching network,
so that MSTP can automatically calculate and give the moderate values for the time
parameters.
For the related command, see stp timer forward-delay, stp timer hello, stp
bridge-diameter.
Example
# Set Max Age of the device to 1000 centiseconds.
[Quidway] stp timer max-age 1000
1.1.38 stp transit-limit
Syntax
stp transit-limit packetnum
undo stp transit-limit
View
Ethernet port view
Parameter
packetnum: Specifies the amount limit to the transmitted packets, ranging from 1 to 255
(expressed as a counter value without any units). By default, the value is 3.
Description
Using stp transit-limit command, you can configure an amount limit to the
configuration BPDU transmitted via a port during the Hello Time. Using undo stp
transit-limit command, you can restore the default limit.
The larger the value is, the more packets can be transmitted in a time unit, yet the more
switch resources will be occupied. With a moderate value, the amount of the BPDUs
transmitted during Hello Time via every port can be limited and MSTP will not occupy
too many bandwidth resources when the network topology flaps.
For the related command, see stp interface transit-limit.
Example
# Set a limit of 5 to the packets transmitted via Ethernet 0/1.
[Quidway-Ethernet0/1] stp transit-limit 5
