Ingress Limit Mode
These bits determine what kinds of frames are limited and
counted against ingress rate limiting.
00 = Limit and count all frames
01 = Limit and count Broadcast, Multicast, and flooded unicast
frames
10 = Limit and count Broadcast and Multicast frames only
11 = Limit and count Broadcast frames only
Count IFG bytes
1 = Each frame’s minimum inter frame gap
(IFG) bytes (12 per frame) are included in Ingress and Egress
rate limiting calculations.
0 = IFG bytes are not counted.
Count Preamble bytes
1 = Each frame’s preamble bytes (8 per frame) are included in
Ingress and Egress rate limiting calculations.
0 = Preamble bytes are not counted.
