stp transmit-limit
Use stp transmit-limit to set the BPDU transmission rate of a port.
Use undo stp transmit-limit to restore the default.
Syntax
stp transmit-limit limit
undo stp transmit-limit
Default
The BPDU transmission rate of all ports is 10.

Parameters
limit: Specifies the BPDU transmission rate in the range of 1 to 255.
Usage guidelines
The maximum number of BPDUs a port can send within each hello time equals the BPDU transmission rate plus the hello timer value.
A larger BPDU transmission rate value requires more system resources. An appropriate BPDU transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources during network topology changes. As a best practice, use the default value.
If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
If this command is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface.
If this command is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group.
Examples
# Set the BPDU transmission rate of Ten-GigabitEthernet 1/0/1 to 5.
<Sysname> system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] stp transmit-limit 5
