times of the hello time.

packetnum: Maximum number of configuration BPDUs a port can transmit in each hello time. This 

argument ranges from 1 to 255. 

interface-list: Ethernet port list. You can specify multiple Ethernet ports by providing this argument in the 

form of interface-list = { interface-type interface-number [ to interface-type interface-number ] } &<1-10>, 

where &<1-10> means that you can provide up to 10 port indexes/port index ranges for this argument. 

z 

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 restore 

the maximum number to the default value on the current port. 

z 

Use the stp interface transmit-limit command to set the maximum number of configuration 

BPDUs each specified port can send in each hello time. Use the undo stp interface 

transmit-limit command to restore the maximum number to the default value for each specified 

port. 

By default, the maximum number of configuration BPDUs a port can transmit in each hello time is 10. 

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 you are recommended 

configure it to a proper value to avoid network topology jitter and prevent MSTP from occupying too 

many bandwidth resources.
