switchport access vlan
switchport access vlan
Use the switchport access vlan interface configuration command to configure a port as a static-access
or dynamic-access port. If the switchport mode is set to access (by using the switchport mode interface
configuration command), use this command to set the port to operate as a member of the specified VLAN
or to specify that the port uses VLAN Membership Policy Server (VMPS) protocol where VLAN
assignment based on the incoming packets it receives. Use the no form of this command to reset the
access VLAN mode to the default VLAN for the switch.
switchport access vlan {vlan-id | dynamic}
no switchport access vlan
Syntax Description
Defaults The default access VLAN and trunk interface native VLAN is a VLAN corresponding to the platform or
interface hardware.
A dynamic-access port is initially a member of no VLAN and receives its assignment based on the packet
it receives.
Command Modes Interface configuration
Command History
Usage Guidelines The no switchport access vlan command resets the access mode VLAN to the appropriate default
VLAN for the device.
The port must be in access mode before the switchport access vlan command can take effect.
An access port can be assigned to only one VLAN.
The VMPS server (such as a Catalyst 6500 series switch) must be configured before a port is configured
as dynamic.
vlan-id Configure the interface as a static access port with the VLAN ID of the
access mode VLAN; the range is 1 to 4094.
dynamic Specify that the access mode VLAN is dependent on the VMPS protocol.
The port is assigned to a VLAN based on the source MAC address of a host
(or hosts) connected to the port. The switch sends every new MAC address
received to the VMPS server to obtain the VLAN name to which the
dynamic-access port should be assigned. If the port already has a VLAN
assigned and the source has already been approved by the VMPS, the switch
forwards the packet to the VLAN.
Note This keyword is visible only on user network interfaces (UNIs) or
enhanced network interfaces (ENIs).
