Configure the
maximum
transmission speed of
the port
You can configure the maximum transmission speed of ports with either of the above
two methods.
A too high maximum transmission speed can cause too many MSTP BPDUs
transmitted in each Hello time interval, resulting in waste of network resources. The
default is recommended.
Configuration example
Set the maximum transmission speed of interface Ethernet1/0/1 to 5.
1 Configure in system view.

Edge ports are ports that do not have any switches connected to them directly or
through networks. After a port is configured to be an edge port, the port can perform
rapid transition, that is, it can move from the blocking state to the forwarding state
without waiting for the delay timer to time out.
You can configure a port to be an edge port or non-edge port in either system view or
Ethernet port view.
