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.
Description
=1, Port 3 inverted refclk selected
=0, Port 3 original refclk selected
Ingress data rate limit for priority 0 frames
Ingress traffic from this priority queue is shaped according to the
ingress Data Rate Limit Table.
