Usage Guidelines
This command is supported on all spanning-tree modes.
The transmit hold count determines the number of BPDUs that can be sent before pausing for 1 second.
Increasing the transmit-hold count value can have a significant impact on CPU utilization, especially in
Rapid Per-VLAN Spanning Tree (PVST+) mode. Decreasing this value might result in slow convergence.
We recommend that you used the default setting.
