Spanning trees may be regenerated even in a steady network if an upstream switch
continues to be busy. You can configure the timeout time factor to a larger number to
avoid this. Normally, the timeout time can be four (or more) times of the Hello time. For
a steady network, the timeout time can be five to seven times of the Hello time.
Example
# Set the Hello time factor to 7.

Syntax
stp transmit-limit packetnum

Parameter
packetnum
: Maximum number of configuration BPDUs a port can transmit in each
Hello time. This argument ranges from 1 to 255 and defaults to 10.
Description
Use the
stp transmit-limit
command to set the maximum number of configuration
BPDUs the current port can transmit in each Hello time.
Use the
undo stp transmit-limit
command to revert to the default maximum number.
A larger number configured by the
stp transmit-limit
command allows more
configuration BPDUs can be transmitted in each Hello time, which may occupy more
switch resources. So configure it to a proper value to avoid MSTP from occupying too
many network resources.
Related command:
stp interface transmit-limit
.
Example
# Set the maximum number of configuration BPDUs that can be transmitted by the
Ethernet1/0/1 port in each Hello time to 15.
