Cisco TrustSec – ISE (Part 6) - 802.1X(AD)

Cisco TrustSec – ISE (Part 6)

             802.1X(AD)

9.  802.1X(AD)



802.1X Authentication Process





By default:

When a client accesses to switch, switch sends EAP-Request 802.1x to the client;

When a client accesses to switch and if the Client doesn’t receive any EAP-request 帧frames,the client sends  EAPoL Start  frame to the switch;
When a client acceses,and doesn’t get EAPoL Start frames,client considers this port as authorization status;



Beginning:after a PC  accesses to switch and sends EAPoL Start request,switch replys to  PC and forward request to ISE.

Middle : switch tells ISE that there is a802.1X authentication request (IETF:NAS-Port- Type=Ethernet,IETF:Service-Type=Framed); ISE starts receiving password,and start setting up a EAP connection,in which contains username and password;ISE determines the group that the user belongs,according to permissions (Vlan DACL etc;),and then sends permission to switch;

End:traffic passes
