6. spanning-tree vlan vlan-id max-age seconds Configures the maximum-aging time of a VLAN.
7. spanning-tree transmit hold-count value Configures the number of BPDUs that can be sent before
pausing for 1 second.
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.
