Description
Port VLAN membership
Define the port’s Port VLAN membership. Bit 2 stands for the host port,
bit 1 for port 2, and bit 0 for port 1. The Port can only communicate within
the membership. An ‘1’ includes a port in the membership; an ‘0’
excludes a port from the membership.

Ingress Limit Mode.
These bits determine what kinds of frames are limited and counted
against Ingress limiting as follows:
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
