We recommend that you use the defaultsetting.Configuration example# Set the maximum transmission rate of port GigabitEthernet 1/0/1 to 5. system-view[Sysname] interface gigabitethernet 1/0/1[Sysname-GigabitEthernet1/0/1] stp transmit-limit 5Configuring Ports as Edge PortsIf a port directly connects to a user terminal rather than another device or a shared LAN segment, thisport is regarded as an edge port. When a network topology change occurs, an edge port will not causea temporary loop. Because a device does not know whether a port is directly connected to a terminal,you need to manually configure the port to be an edge port. After that, this port can transition rapidlyfrom the blocked state to the forwarding state without delay.
