Displaying 802.1X Open VLAN mode status

Examine the switch current VLAN status by using the show port-access authenticator vlan and show port-access authenticator <port-list> commands. The following figure shows related VLAN data that can help you to see how the switch is using statically configured VLANs to support 802.1X operation.

Showing ports configured for open VLAN mode
In the output shown in Showing ports configured for open VLAN mode:

  • When the Auth VLAN ID is configured and matches the Current VLAN ID, an authenticated client is connected to the port. This assumes the port is not a statically configured member of the VLAN you are using for Auth VLAN.

  • When the Unauth VLAN ID is configured and matches the Current VLAN ID, an unauthenticated client is connected to the port. This assumes the port is not a statically configured member of the VLAN you are using for Unauth VLAN.

NOTE:

Because a temporary Open VLAN port assignment to either an authorized or unauthorized VLAN is an untagged VLAN membership, these assignments temporarily replace any other untagged VLAN membership that is statically configured on the port. For example, if port 12 is statically configured as an untagged member of VLAN 1, but is configured to use VLAN 25 as an authorized VLAN, then the port's membership in VLAN 1 is temporarily suspended whenever an authenticated 802.1X client is attached to the port.

Access Control
This state is controlled by the following port-access command syntax: 

aaa port-access authenticator <port-list> control {<authorized | auto | unauthorized>}
AutoConfigures the port to allow network access to any connected device that supports 802.1X authentication and provides valid 802.1X credentials.This is the default authenticator setting.AuthorizedConfigures the port for "Force Authorized", which allows access to any device connected to the port, regardless of whether it meets 802.1X criteria. You can still configure console, Telnet, or SSH security on the port.UnauthorizedConfigures the port for "Force Unauthorized", which blocks access to any device connected to the port, regardless of whether the device meets 802.1X criteria.
Unauthorized VLAN ID

<vlan-id>Lists the VID of the static VLAN configured as the unauthorized VLAN for the indicated port.0No unauthorized VLAN has been configured for the indicated port.

Authorized VLAN ID

<vlan-id>Lists the VID of the static VLAN configured as the authorized VLAN for the indicated port.0No authorized VLAN has been configured for the indicated port.

Status

ClosedEither no client is connected or the connected client has not received authorization through 802.1X authentication.OpenAn authorized 802.1X supplicant is connected to the port.

Current VLAN ID

<vlan-id>Lists the VID of the static, untagged VLAN to which the port currently belongs.No PVIDThe port is not an untagged member of any VLAN.
