164 CHAPTER 14: MSTP CONFIGURATION
prevent MSTP from occupying too many network resources. The default value is
recommended.
Configuration example
# Set the maximum transmitting speed of Ethernet 1/0/1 to 15.
1 Configure the maximum transmitting speed in system view
<4210> system-view
[4210] stp interface Ethernet1/0/1 transmit-limit 15
2 Configure the maximum transmitting speed in Ethernet port view
<4210> system-view
[4210] interface Ethernet1/0/1
[4210-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.
Configure a port as an edge port in system view
Configure a port as an edge port in Ethernet port view
On a switch with BPDU guard disabled, an edge port becomes a non-edge port
again once it receives a BPDU from another port.
n
You are recommended to configure the Ethernet ports connected directly to
terminals as edge ports and enable the BPDU guard function at the same time.
This not only enables these ports to turn to the forwarding state rapidly but also
secures your network.
Tabl e 115 Configure a port as an edge port in system view
Operation Command Description
