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.
