Command History
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.
