Context
The more BPDUs sent from an interface within a Hello Time interval, the more system resources consumed. Setting a proper transmission rate (packet-number) on an interface prevents excess bandwidth usage when network flapping occurs.
Procedure
Run:
system-view
The system view is displayed.
Run:
interface interface-type interface-number
The view of an Ethernet interface participating in STP calculation is displayed.
Run:
stp transmit-limit packet-number
The maximum transmission rate of BPDUs (BPDUs per second) is set for the interface.
By default, an interface sends a maximum of six BPDUs per second. If the same maximum transmission rate of BPDUs needs to be sent for each interface on a device, run the stp transmit-limit (system view) command.
