Learn how to configure the transmit hold-count to control the BPDU burst size and manage the number of BPDUs sent before pausing.

You can configure the BPDU burst size by changing the transmit hold count value to control the number of BPDUs that can be sent before pausing.

This task enables you to adjust the transmit hold-count. Changing this parameter to a higher value can have a significant impact on CPU utilization, especially in rapid PVST+ mode, so maintain the default setting unless specifically required.

Note

Changing this parameter to a higher value increases CPU utilization, especially in rapid PVST+ mode. Use the default value unless you need a different setting.

Before you begin

Perform these steps to configure transmit hold-count.

Procedure

1.

Use the enable command to enter privileged EXEC mode.

Example:

Switch> enable

Enter your password if prompted.
2.

Use the configure terminal command to enter global configuration mode.

Example:

Switch# configure terminal
3.

Use the spanning-tree transmit hold-count value command to configure the transmit hold-count.

Example:

Switch(config)# spanning-tree transmit hold-count 6

For hold-count, the values range from 1 to 10 seconds. The default value is 6.
4.

Use the end command to return to privileged EXEC mode.

Example:

Switch(config)# end
