spanning-tree transmit hold-count

Use the spanning-tree transmit hold-count global configuration command to configure the number of
bridge protocol data units (BPDUs) sent every second. Use the no form of this command to return to the
default setting.

Usage Guidelines Increasing the transmit hold-count value can have a significant impact on CPU utilization when the
switch is in rapid-per-VLAN spanning-tree plus (rapid-PVST+) mode. Decreasing this value might slow
down convergence. We recommend using the default setting.
Examples
This example shows how to set the transmit hold count to 8:
Switch(config)# spanning-tree transmit hold-count 8
You can verify your setting by entering the show spanning-tree mst privileged EXEC command.
