Configures the Layer 2 interface attribute (port type).
access
Sets the applicable interface as an access port. An access port sends
untagged frames. An access port can be used by only one VLAN.
trunk
Sets the applicable interface as a trunk port. A trunk port sends and receives
untagged frames and tagged frames.
protocol-vlan
Sets the applicable interface as a protocol port. A protocol port sends and
receives untagged frames. When a frame is received, the VLAN is determined
by the protocol type of the frame. Tagged frames are discarded.
mac-vlan
Sets the applicable interface as a MAC port. A MAC port sends and receives
untagged frames. When a frame is received, the corresponding VLAN is
determined from the source MAC address of the frame. Tagged frames are
discarded. Note, however, that if the
switchport mac dot1q vlan command
is set, tagged frames are forwarded.
