Configure the maximum 
transmitting rate 
stp transmit-limit packetnum 
Required 
The maximum transmitting rate 
of all Ethernet ports on a switch 
defaults to 10. 
 
As the maximum transmitting rate parameter determines the number of the configuration BPDUs 
transmitted in each hello time, set it to a proper value to prevent MSTP from occupying too many 
network resources. The default value is recommended. 
Configuration example 
# Set the maximum transmitting rate of Ethernet 1/0/1 to 15. 
1)  Configure the maximum transmitting rate in system view 
<Sysname> system-view 
[Sysname] stp interface Ethernet 1/0/1 transmit-limit 15 
2)  Configure the maximum transmitting rate in Ethernet port view 
<Sysname> system-view 
[Sysname] interface Ethernet 1/0/1 
[Sysname-Ethernet1/0/1] stp transmit-limit 15 
Configuring the Current Port as an Edge Port 
Edge ports are ports that neither directly connects to other switches nor indirectly connects to other 
switches through network segments. After a port is configured as an edge port, the rapid transition 
mechanism is applicable to the port. That is, when the port changes from the blocking state to the 
forwarding state, it does not have to wait for a delay. 
You can configure a port as an edge port in one of the following two ways.
