Usage Guidelines A configuration that uses the access, dot1q-tunnel, or trunk keywords takes effect only when you
configure the port in the appropriate mode by using the switchport mode command. The static-access
and trunk configuration are saved, but only one configuration is active at a time.
When you enter access mode, the interface changes to permanent nontrunking mode and negotiates to
convert the link into a nontrunk link even if the neighboring interface does not agree to the change.
When you enter trunk mode, the interface changes to permanent trunking mode and negotiates to
convert the link into a trunk link even if the interface connecting to it does not agree to the change. If
you do not intend to trunk across those links, use the switchport mode access interface configuration
command to disable trunking.
When you enter dot1q-tunnel, the port is set unconditionally as an IEEE 802.1Q tunnel port.
Access ports, and trunk ports, and tunnel ports are mutually exclusive.

switchport mode {access | dot1q-tunnel | private-vlan | trunk}
no switchport mode
Set the port to access mode (either static-access or dynamic-access depending
on the setting of the switchport access vlan interface configuration command).
The port is set to access unconditionally and operates as a nontrunking, single
VLAN interface that sends and receives unencapsulated (nontagged) frames.
An access port can be assigned to only one VLAN.
Set the port as an IEEE 802.1Q tunnel port. This keyword is supported only
when the metro IP access or metro access image is running on the switch.
See the
Set the port to trunk unconditionally. The port is a trunking VLAN Layer 2
interface. The port sends and receives encapsulated (tagged) frames that
identify the VLAN of origination. A trunk is a point-to-point link between two
switches or between a switch and a router.
