Default

Null VID Lookup Enable

How to handle tagged packets with VID = 0.

1 = Non-standard operation. VLAN Table lookup using VID = 0.

0 = Standard operation. VLAN Table lookup using the port default VID (Port

Default Tag 0 Register and Port Default Tag 1 Register)

R/W

Ingress VLAN Filtering

1 = Discard packets whose VID port membership in the VLAN Table does

not include the ingress port

0 = No ingress filtering

R/W

Discard Non-PVID Packet

1 = Discard packets whose VID does not match the ingress port default VID

0 = Do not compare VID to the port default VID

R/W

MAC Based 802.1X Enable

1 = Enable MAC based 802.1X authentication in lookup engine

0 = Only use ACL (if enabled) to perform MAC based authentication

R/W

Self-Address Filtering – Port Enable

The source address of received packets is compared to the MAC address in

the Switch MAC Address 0 Register through Switch MAC Address 5

Both this port enable bit and the global enable bit in the Switch Lookup

Engine Control 1 Register must be set to enable self-address filtering.

1 = Enable self-address filtering for this port.
