How ports of different link types handle frames

Actions Access

Trunk

Hybrid

In the
inbound
direction for

an untagged

frame

Tags the frame with the
PVID tag.

If the PVID is permitted on the port, tags the frame with the PVID

tag.

If not, drops the frame.

In the
inbound

direction for

a tagged
frame

Receives the frame if
its VLAN ID is the

same as the PVID.

Drops the frame if its

VLAN ID is different

from the PVID.

Receives the frame if its VLAN is permitted on the port.

Drops the frame if its VLAN is not permitted on the port.

In the
outbound

direction

Removes the VLAN tag
and sends the frame.

Removes the tag and sends

the frame if the frame carries
the PVID tag and the port

belongs to the PVID.

Sends the frame without

removing the tag if its VLAN

is carried on the port but is

different from the PVID.

Sends the frame if its VLAN is
permitted on the port. The

tagging status of the frame

depends on the port hybrid vlan
command configuration.

In a VLAN-aware network, the default processing order for untagged packets is as follows, in

descending order of priority:

MAC-based VLANs.

IP subnet-based VLANs.

Protocol-based VLANs.

Port-based VLANs.
