466 CHAPTER 23: MSTP C ONFIGURATIONn ■ Timeout time = timeout factor × 3 × hello time.■ Typically, we recommend that you set the timeout factor to 5, or 6, or 7 for astable network.Configuration example# Set the timeout factor to 6. system-view[Sysname] stp timer-factor 6Configuring theMaximum TransmissionRate of PortsThe maximum transmission rate of a port refers to the maximum number of MSTPpackets that the port can send within each hello time.The maximum transmission rate of an Ethernet port is related to the physicalstatus of the port and the network structure.Configuration procedureFollowing these steps to configure the maximum transmission rate of a port or agroup of ports:n ■ If the maximum transmission rate setting of a port is too big, the port will senda large number of MSTP packets within each hello time, thus using excessivenetwork resources. We recommend that you use the default setting.■ Refer to “Aggregation Port Group” on page 349 for information about portgroups.Configuration example# Set the maximum transmission rate of port Ethernet 1/0 to 5. system-view[Sysname] interface ethernet 1/0[Sysname-Ethernet1/0] stp transmit-limit 5Configure the timeout factorof the devicestp timer-factor number Optional3 by defaultTo do...
