ONFIGURATION

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.

Set the maximum transmission speed of interface Ethernet1/0/1 to 5.

1 Configure in system view.

2 Configure in Ethernet port 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.
