For detail descriptions of interface-type andinterface-number parameters, refer to the corresponding descriptions in PortCommand Manual. &<1-10> means that the preceding parameters can beentered up to 10 times.packetnum: Maximum number of configuration BPDUs that can be transmitted viathe port per Hello Time, ranging from 1 to 255 (expressed as a counter valuewithout any units). By default, the transmission limit on every port is 3.DescriptionUse the stp interface transmit-limit command to configure an amount limit tothe configuration BPDU transmitted via a specified port during the Hello Time insystem view.Use the undo stp interface transmit-limit command to restore the default limiton the specified port in system view.The larger the value is, the more packets can be transmitted in a time unit, yet themore switch resources will be occupied. With a moderate value, the amount of theBPDUs transmitted during Hello Time via every port can be limited and MSTP willnot occupy too many bandwidth resources when the network topology flaps.Related command: stp transmit-limit.Example# Set a limit of 5 to the packets transmitted via Ethernet2/1/3 in system view.system-viewSystem View: return to User View with Ctrl+Z.[SW8800] stp interface Ethernet2/1/3transmit-limit 5
