Quidway S8500 Series Routing Switches
the switch will decide the upstream switch is dead and will recalculate the topology of
the network. Then in steady network, the recalculation may be caused when the
upstream is busy. In this case, users can redefine the timeout interval to a longer time
(four times the hello time or larger) by define the multiple of hello time. It is
recommended to set 5, 6 or 7 as the value of multiple in the steady network.
Example
# Set the multiple value of hello time to 7.

1.1.42 stp transmit-limit

Syntax
stp transmit-limit packetnum
undo stp transmit-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
Use the stp transmit-limit command to configure an amount limit to the configuration
BPDU transmitted via a port during the Hello Time.
Use the undo stp transmit-limit command to 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.
Related command: stp interface transmit-limit.
Example
# Set a limit of 5 to the packets transmitted via Ethernet2/1/1.
