Configuring Port-Based and User-Based Access Control (802.1X)

Displaying 802.1X Configuration, Statistics, and Counters

Viewing 802.1X Open VLAN Mode Status

You can examine the switch’s current VLAN status by using the show port- access authenticator vlan and show port-access authenticator < port-list> commands as illustrated in figure 10-17.Table 10-2 describes the data that these two commands display. Figure 10-18shows related VLAN data that can help you to see how the switch is using statically configured VLANs to support 802.1X operation.

In these two show outputs, an Unauth VLAN ID appearing in the Current VLAN ID column for the same port indicates an unauthenticated client is connected to this port. (Assumes that the port is not a statically configured member of VLAN 100.)

Items 1 through 3 indicate that an authenticated client is connected to port 2: 1.Open in the Status column

2.Authorized in the Authenticator State column

3.The Auth VLAN ID (101) is also in the Current VLAN ID column. (This assumes that the port is not a statically configured member of VLAN 101.)

4.A “0” in the row for port 3 indicates there is no Authorized VLAN configured for port 3. 5.No PVID” means there is currently no untagged VLAN membership on port 4.
