Configuring Transmit Hold Count

Transmit hold count value is a counter used to limit the maximum transmission rate of the switch.

The number or BPDUs that can be transmitted during every Hello Time period ranges from a minimum of one and a maximum of not more than TxHoldCount values.

Execute the following commands in the switch.

Type the following:

  • Enter the Global Configuration Mode.
iS5comm# configure terminal
  • Configure the Transmit Hold Count.
iS5comm(config)# spanning-tree transmit hold-count 9
The transmit hold count ranges from 1-10. The default value is 3.
  • Return to the Privileged EXEC mode.
iS5comm(config)#end
  • View the spanning tree details..
iS5comm# show spanning-tree detail
