Configure 802.1 x authentication on all access switch ports connecting to LAN outlets (i.e., RJ-45 wall plates) or devices not located in the telecom room, wiring closets, or equipment rooms. Configure MAB on those switch ports connected to devices that do not support an 802.1x supplicant.
Verify if the switch configuration has 802.1x authentication implemented for all access switch ports connecting to LAN outlets (i.e., RJ-45 wall plates) or devices not located in the telecom room, wiring closets, or equipment rooms using the following procedure:
Step 1: Verify that an 802.1x authentication server has been configured similar to the following example:
radius-server host x.x.x.x auth-port 1813 key xxxxxxxxxxxxx
aaa new-model
aaa authentication dot1x default group radius
Step 2: Verify 802.1x authentication has been enabled globally on the network device similar to the following example:
dot1x system-auth-control
Step 3: Verify that all host-facing access switchports are configured to use 802.1x similar to the examples below:
interface fastethernet0/2
switchport mode access
dot1x port-control auto
Note: The “force-authorized” attribute must not be configured in leu of “auto” on the “dot1x port-control” command as this will bypass authentication and enable the switchport in an authorized state.
Note: MAC Authentication Bypass (MAB) must be configured on those switch ports connected to devices that do not support an 802.1x supplicant as shown in the following example:
interface fastethernet0/2
switchport mode access
dot1x mac-auth-bypass
If 802.1x authentication or MAB is not configured on all access switch ports connecting to LAN outlets or devices not located in the telecom room, wiring closets, or equipment rooms, this is a finding.
