R/W

UNI_LEAKY_EN_0

unicast frame leaky VLAN enable.

Also use ARL_UNI_LEAKY_EN and

LEAKY_EN bit in ARL table to control

unicast leaky VLAN.

When ARL_UNI_LEAKY_EN is set to

zero, only UNI_LEAKE_EN control

unicast frame leaky VLAN.

If ARL_UNI_LEAKY_EN is set to 1'b1,

only frame with DA in ARL table and

LEAKY_EN bit is set to 1'b1 can be

forward as leaky VLAN, ignore

UNI_LEAKY_EN.

if mac receive unicast frame from this

port which should forward as leaky

VLAN, the frame could be switched to

destination port defined in ARL table

and cross all VLAN ( include port base

and 802.1q ).

R/W

MULTI_LEAKY_EN_0

lso use ARL_MULTI_LEAKY_EN and

LEAKY_EN bit in ARL table to control

unicast leaky VLAN.

When ARL_MULTI_LEAKY_EN is set

to zero, only MULTI_LEAKY_EN

control multicast frame leaky VLAN.

If ARL_MULTI_LEAKY_EN is set to

1'b1, only frame with DA in ARL table

and LEAKY_EN bit is set to 1'b1 can be

forward as leaky VLAN, ignore

MULTI_LEAKY_EN.

if mac receive multicast frame from this

port which should forward as leaky

VLAN, the frame could be switched to

destination port defined in ARL table

and cross all VLAN ( include port base

VLAN and 802.1q ).

R/W

ARP_LEAKY_EN_0

1'b1: if mac receive ARP frame from

this port, it can cross all VLAN (

include port base VLAN and 802.1q ).

1'b0: ARP frame can't cross vlan

Ingress port mirror. If this bit is set to

1'b1, all packets received from this port

should be copied to mirror port.

R/W

NG_MIRROR_EN_0

Ingress port mirror. If this bit is set to

1'b1, all packets received from this port

should be copied to mirror port.
