Configuration Guidelines
The tag attributes are configured for MAC ports and VCTRUNK ports. Hence, the VCTRUNK
ports at both ends of the trunk link can be configured with the tag attributes. In the case of a link,
the services are available only when the parameters of the tag attributes are the same for the
VCTRUNK ports on the source and sink ports. No requirements are proposed for the tag
attributes of MAC ports.

Default Value
Tag Aware
Description
A port receives only the packets that do not
contain VLAN tags. After receiving the packets,
the port adds the default VLAN tag (PVID) to
these packets. When the packets are transmitted
from the port, the VLAN tags are stripped off the
packets.
A port receives only the packets that contain
VLAN tags and discards the packets that do not
contain VLAN tags. When the packets are
transmitted from the port, they are directly
forwarded to the next port.
A port can receive all the packets regardless of
VLAN tags. After receiving the packets that do
not contain VLAN tags, the port adds the default
VLAN tag (PVID) to these packets. When the
packets are transmitted from the hybrid port, the
egress port determines whether the VLAN tags
contained in the packets are the same as the
PVID. If yes, the egress port strips the VLAN
tags off the packets and then forwards these
packets. Otherwise, the egress port directly
forwards these packets.
