(Optional) Configuring the Transmit Hold-Count You can configure the BPDU burst size by changing the transmit hold count value. Note Changing this parameter to a higher value can have a significant impact on CPU utilization, especially in Rapid PVST+ mode. Lowering this value can slow down convergence in certain scenarios. We recommend that you maintain the default setting. To configure the transmit hold-count, perform this procedure: Procedure Configuring Spanning Tree Protocol (Optional) Configuring the Transmit Hold-Count Command or Action Purpose range of VLANs separated by a hyphen, or a series of VLANs separated by a comma. The range is 1 to 4094.
• For seconds, the range is 6 to 40; the default is 20. Step 4 end Example: Device(config-if)# end Returns to privileged EXEC mode. Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Step 3 spanning-tree transmit hold-count value Example: Device(config)# spanning-tree transmit hold-count 6 Configures the number of BPDUs that can be sent before pausing for 1 second. For value, the range is 1 to 20; the default is 6. Step 4 end Example: Device(config)# end Returns to privileged EXEC mode.
