When a Spirent TestCenter VN_Port’s SubState reaches FLOGI (or FDISC) accepted (even though it does not ever reach the PLOGI accepted substate) should we expect keepalives to start being sent?
Yes, as per the FIP state machine,
on Discovery complete, the Enode MAC starts sending the Keepalives – the first type of keepalive which is sent at the FKA_ADV interval, and
on Flogi or FDisc accept, the VN port MAC starts sending Keepalives – the second type of keepalive which is sent every 90 seconds.
