Dot1x allowing non authenticated wired users on the network



I am in the testing phase of dot1x for wired user authentication. I am using a 7506 switch running comware 5.20.


below is the global configuration:



 radius nas-ip
 domain default enable
 ip ttl-expires enable
 ip unreachables enable
 lldp enable
 lldp compliance cdp
 port-security enable
 dot1x quiet-period
 dot1x timer quiet-period 30
 dot1x retry 3
 dot1x timer handshake-period 30
 dot1x authentication-method eap
radius scheme radius_auth
 primary authentication key cipher xxxxxxx
 primary accounting key cipher xxxxxxx
 secondary authentication key cipher xxxxxxx
 secondary accounting key cipher xxxxxxx
 user-name-format without-domain
 accounting-on enable
 authentication login hwtacacs-scheme tacacs_auth local
 authorization login hwtacacs-scheme tacacs_auth local
 accounting login hwtacacs-scheme tacacs_auth local
 authentication lan-access radius-scheme radius_auth
 authorization lan-access radius-scheme radius_auth
 accounting lan-access radius-scheme radius_auth
 access-limit disable
 state active   
 idle-cut disable
 self-service-url disable




The interface configuration:



interface GigabitEthernet2/0/42
 port link-mode bridge
 description Wall Plate # 13
 port link-type hybrid
 undo port hybrid vlan 1
 port hybrid vlan 2265 tagged
 port hybrid vlan 2264 untagged
 port hybrid pvid vlan 2264
 undo voice vlan mode auto
 voice vlan qos trust
 voice vlan 2265 enable
 poe enable
 lldp compliance admin-status cdp txrx
 qos trust dscp
 port-security port-mode userlogin-secure-or-mac
 undo dot1x handshake
 dot1x mandatory-domain
 dot1x unicast-trigger




The plan is to get dot1x for data VLAN and ip phones get MAB authenticated on the voice VLAN. Also, I already configured my RADIUS server (Cisco ISE). Now when I connect my laptop without a supplicant configured, the connection hangs in there for 30 seconds or so, and then I get full network access. Basically, I am not authenticating but it is still letting me in.  Even when I configured my supplicant, I am still failing the authentication on the RADIUS server, but the switch is letting me in after 30 seconds.  What am I missing?

Below is the output of the dot1x interface command:
