Configuring the BPDU transmission rate

The maximum number of BPDUs a port can send within each hello time equals the BPDU transmission rate plus the hello timer value. Configure an appropriate BPDU transmission rate based on the physical status of the port and the network structure.

The higher the BPDU transmission rate, the more BPDUs are sent within each hello time, and the more system resources are used. By setting an appropriate BPDU transmission rate, you can limit the rate at which the port sends BPDUs. Setting an appropriate rate also prevents spanning tree protocols from using excessive network resources when the network topology changes. As a best practice, use the default setting.

To configure the BPDU transmission rate:

The default setting is 10.
