switchport mode
To configure the VLAN membership mode of a port, use the
switchport mode
command in interface
configuration mode. To reset the mode to the appropriate default for the device, use the
no
form of this
command.

access| dynamic
| {
auto| desirable
}

}

Syntax Description
Sets 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 nonencapsulated (non-tagged) frames. An access port can be assigned
to only one VLAN.
access
Sets the port trunking mode dynamic parameter to auto to specify that the interface
convert the link to a trunk link. This is the default switchport mode.
dynamic auto
Sets the port trunking mode dynamic parameter to desirable to specify that the interface
actively attempt to convert the link to a trunk link.
dynamic desirable
Sets 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 controllers or between a
controller and a router.

Usage Guidelines
Although visible in the CLI, the
dot1q-tunnel
keyword is not supported.
Note
A configuration that uses the
access
,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.
