MSTP Configuration Commands

1.1.44 stp transmit-limit
Syntax
stp transmit-limit packetnum
undo stp transmit-limit
View
Ethernet port view
Parameters
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 to 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 commands: stp interface transmit-limit.
Examples
# Set the maximum number of configuration BPDUs that can be transmitted by
Ethernet 2/0/1 in each Hello time to 15.
