H3C MSR Series Command Reference Manual page 97

Syntax
stp transmit-limit limit
undo stp transmit-limit
Default
The maximum transmission rate of all ports is 10. Each port can send up to 10 BPDUs within each
hello time.
Views
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default command level
2: System level
Parameters
limit: Sets the maximum number of BPDUs the ports can send within each hello time. The value
range is 1 to 255.

Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all member ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port
leaves the aggregation group.
A larger maximum transmission rate value requires more system resources. An appropriate
maximum transmission rate setting can prevent spanning tree protocols from using excessive
bandwidth resources during network topology changes. H3C recommends that you use the default
value.
Examples
# Set the maximum transmission rate of port Ethernet 1/1 to 5.
