parameter. It depends on the physical state of the port and network structure. You
can configure this parameter according to the network.
Configuration procedure (in system view)
Table 181 Configure the maximum transmitting speed for specified ports in system view
Operation
Enter system view
Configure the maximum
transmitting speed for
specified ports
Configuration procedure (in Ethernet port view)

Configure the stp transmit-limit packetnum
maximum
transmitting speed
As the maximum transmitting speed parameter determines the number of the
configuration BPDUs transmitted in each Hello time, set it to a proper value to
avoid MSTP from occupying too many network resources. The default is
recommended.
Configuration example
# Set the maximum transmitting speed of Ethernet1/0/1 port to 5.
Configure the maximum transmitting speed in system view.

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, rapid transition is applicable to the port. That is, when the port
changes from blocking state to forwarding state, it does not have to wait for a
delay.
You can configure a port as an edge port in the following two ways.
