Enhanced DATA VLAN 477

was manually configured in the DATA VLAN field. Any packet arriving

on the PC port which is already tagged is dropped.

•

DATA VLAN enabled—all traffic is forwarded to the PC port based on

a review of the MAC address and the 802.1Q value that was manually

configured in the DATA VLAN field. Traffic is forwarded out the PC port

only if the packets contain the DATA VLAN tag. Untagged traffic and

traffic without the DATA VLAN tag is dropped.

DATA (PC Port) VLAN Tag Stripping

DATA VLAN Tag Stripping can be configured in the Network Configuration

menu. To enable DATA VLAN Tag Stripping, select the PC-Port Untag

All check box, DATA VLAN Tag Stripping can be enabled or disabled

independent of enabling VLAN support on the PC Port.

If the DATA VLAN Tag Stripping is disabled, the packet is sent to the PC

Port unmodified. If the DATA VLAN Tag Stripping is enabled, the 802.1Q

header if one exists, is removed from the packet before the packet is

forwarded to the PC port.

During manual configuration, if DATA VLAN is enabled by configuring a

VLAN ID, the PC-Port Untag All check box is selected and is enabled by

default. By default, the egress tag is stripped. To manually override this

setting and disable egress stripping, clear the PC-Port Untag All check

box.

If DATA VLAN is not enabled during manual configuration, the PC-Port

Untag All check box is not selected. By default, the ingress tag is not

stripped. To manually override this setting and enable ingress stripping,

select the PC-Port Untag All check box.
