User Priority Ceiling
1 = if the packet’s “priority field” is greater than the “user priority field” in the port VID control register
bit[15:13], replace the packet’s “priority field” with the “user priority field” in the port VID control
register bit[15:13].
0 = do no compare and replace the packet’s “priority field.”

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. A ‘1’ includes a port in the
membership; a ‘0’ excludes a port from the membership.
Bank 48 Port 1 VID Control Register (0x04): P1VIDCR
This register contains the global per port control for the switch function.

Default Tag[15:13]
Port’s default tag, containing “User Priority Field” bits.

Default Tag[12]
Port’s default tag, containing CFI bit.

0x001
RW
Default Tag[11:0]
Port’s default tag, containing VID[11:0].
Note: This VID Control register serves two purposes:
1. Associated with the ingress untagged packets, and used for egress tagging.
2. Default VID for the ingress untagged or null-VID-tagged packets, and used for address lookup.

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.

0
RW
Count IFG
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.
0
RW
Count Preamble
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.
