In AOS-CX switching, what determines when a frame is forwarded by the switch between the ingress and the egress port?
In AOS-CX switching, the egress port determines when a frame is forwarded by the switch between the ingress and the egress port. This is because, in a VOQ (Virtual Output Queueing) architecture, the egress side selects which traffic will cross the fabric. The egress port then tells the ingress VOQs how much data can be sent into the fabric.
I thought my English is not bad. But I don't get this question
same for me :D
In a VOQ architecture, the egress side selects which traffic will cross the fabric. In the 6400 Switch Series, this block is called the Traffic Regulator, which sends small messages across the fabric to tell ingress VOQs how much they can send into the fabric
VoQ affects traffic traveling between the ingress and egress ports, and in a VOQ architecture, the egress side selects which traffic will cross the fabric. so i think A is answer

"Tx Drops shows the sum of packets that were dropped across all line modules (due to insufficient capacity) by the ingress Virtual Output Queues (VOQs) destined for the egress port." Page 25: https://www.arubanetworks.com/techdocs/AOS-CX/10.07/PDF/5200-7879.pdf
