Application
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.
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.
