• Ports that receive Hello packets before three discovery transmission times expire, send a Hello reply 

and transition to the common transmission state.

• Ports that do not receive Hello packets before three discovery transmission times expire, revert to the 

passive reception state.

• Ports in the passive reception state do not send Hello packets and do not use any timer to determine 

how long to wait for Hello packets.

• The discovery transmission time value is also used by ports in the common transmission state to deter-

mine how long to wait for Hello packets (see
