Tag the frame with the
default VLAN tag.
z Receive the frame if its
VLAN ID is the same as
the default VLAN ID.
z Drop the frame if its
VLAN ID is different
from the default VLAN
ID.
Remove the default VLAN
tag and send the frame.
Trunk
z Remove the tag and send
the frame if the frame
carries the default VLAN
tag and the port belongs
to the default VLAN.
z Send the frame without
removing the tag if its
VLAN is carried on the
port but is different from
the default one.
Hybrid
Check whether the
default VLAN is
permitted on the port:
z If yes, tag the frame
with the default
VLAN tag.
z If not, drop the
frame.
z Receive the frame if its
VLAN is carried on the
port.
z Drop the frame if its
VLAN is not carried on
the port.
Send the frame if its VLAN is
carried 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 default VLAN.
