Make sure a port is assigned to its PVID. Otherwise, when the port receives frames tagged with the PVID
or untagged frames, the port filters out these frames.
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 frame
is sent with the VLAN tag
removed or intact depending on
your configuration with the port
hybrid vlan command. This is
true of the PVID.
