a period three times of the hello time and then initiates the spanning tree recalculation
process.
Spanning trees may be recalculated even in a steady network if an upstream switch is
always busy. You can configure the hello time factor to a larger number to avoid this
problem. 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.
Examples
# Set the hello time factor to 7.

[Sysname] stp timer-factor 7

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.
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 restore the maximum number to the
default value.
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.
