The transmit hold count value is a counter used to limit the maximum transmission rate of the switch. The number or BPDUs transmitted during every hello-time period ranges from a minimum of one to a maximum that is not more than the TxHoldCount value.
TOR-1 SEFOS# configure terminal TOR-1 SEFOS(config)# spanning-tree vlan 10 hold-count 6 Hold Count for the given instance is set TOR-1 SEFOS(config)# end
The transmit hold count value ranges from 1 to 10. The default value is 3.
