Command Modes Interface configuration

Command History

Usage Guidelines 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.

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.

When you enter dynamic auto mode, the interface converts the link to a trunk link if the neighboring

interface is set to trunk or desirable mode.

When you enter dynamic desirable mode, the interface becomes a trunk interface if the neighboring

interface is set to trunk, desirable, or auto mode.

access 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 nonencapsulated (non-tagged) frames.

An access port can be assigned to only one VLAN.

dynamic auto Set the interface 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 desirable Set the interface trunking mode dynamic parameter to desirable to specify that

the interface actively attempt to convert the link to a trunk link.

trunk 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.
