RemarksEnter system view system-view —Enter Ethernet portviewinterface interface-typeinterface-number —Configure themaximumtransmitting speedstp transmit-limitpacketnumRequiredThe maximum transmittingspeed of all Ethernet ports ona switch defaults to 10.As the maximum transmitting speed parameter determines the number of theconfiguration BPDUs transmitted in each Hello time, set it to a proper value to avoidMSTP from occupying too many network resources. The default value isrecommended.III. Configuration example# Set the maximum transmitting speed of Ethernet2/0/1 to 15.1) Configure the maximum transmitting speed in system view. system-view[H3C] stp interface ethernet2/0/1 transmit-limit 152) Configure the maximum transmitting speed in Ethernet port view. system-view[H3C] interface ethernet2/0/1[H3C-Ethernet2/0/1] stp transmit-limit 151.2.11 Edge Port ConfigurationEdge ports are ports that neither directly connects to other switches nor indirectlyconnects to other switches through network segments. After a port is configured as anedge port, rapid transition is applicable to the port. That is, when the port changes fromblocking state to forwarding state, it does not have to wait for any delay.You can configure a port as an edge port in the following two ways.
