I have a doubt about the switch port Egress direction and Ingress direction.
you see the upper have Egress rate limit.
I want to know the Egress to switch port is direction a or direction b?
Ingress and egress are terms (normally) used with network devices like switches and routers. So, switch egress is (a).
"Egress to switch port..." implies the POV from the server (or anything else but the switch).
