Description
Controlling LAN access via 802.1x authentication can assist in preventing a malicious user from connecting an unauthorized PC to a switch port to inject or receive data from the network without detection.
ℹ️ Check
Review configuration for RADIUS server configuration, FlexAuth configuration, and applicable port configuration (optional).

Note: Port configuration is only necessary when specifying which RADIUS server is to be used.
If user ports are not configured to control LAN access via 802.1X, this is a finding.
✔️ Fix
Configure 802.1x to authenticate endpoint devices.
1. Configure RADIUS as the authentication method for 802.1x.
ICX(config)#radius-server host x.x.x.x auth-port 1812 acct-port 1813 default key xxxxx dot1x mac-auth no-login
2. Configure the dot1x authentication.
ICX(config)#authentication
ICX(config-authen)# auth-default-vlan 100
ICX(config-authen)# re-authentication
ICX(config-authen)# reauth-period 2000
ICX(config-authen)# dot1x enable
ICX(config-authen)# dot1x enable ethernet 1/1/14 to 1/1/15
ICX(config-authen)# dot1x max-req 6
ICX(config-authen)# dot1x timeout tx-period 60
