Trunk
port
l Adds a tag with
the default
VLAN ID to an
untagged frame
and accepts the
frame if the port
permits the
default VLAN
ID.
l Adds a tag with
the default
VLAN ID to an
untagged frame
and discards the
frame if the port
denies the default
VLAN ID.
l Accepts a
tagged
frame if the
port permits
the VLAN
ID carried in
the frame.
l Discards a
tagged
frame if the
port denies
the VLAN
ID carried in
the frame.
l Removes the
tag from a
received
frame and
sends the
frame if the
VLAN ID
carried in the
frame is the
same as the
default
VLAN ID
and
permitted by
the port.
l Directly
sends a
received
frame if the
VLAN ID
carried in the
frame is
different
from the
default
VLAN ID
but permitted
by the port.
A trunk port
can be added to
multiple
VLANs to send
and receive
frames for these
VLANs. A
trunk port
connects a
switch to
another switch
or to a router.
Hybrid
port
Sends a received
frame if the port
permits the
VLAN ID
carried in the
frame. A
specified
command can be
used to
determine
whether a hybrid
port sends
frames with or
without tags.
A hybrid port
can be added to
multiple
VLANs to send
and receive
frames for these
VLANs. A
hybrid port can
connect a
switch to a PC
or connect a
network device
to another
network
device.
