Do you have a floating device configured that shows the old mac address from the controller that existed before the upgrade?</P><P></P><P>Thanks,</P><P></P><P></P><P>Tarik Admani <BR />*Please rate helpful posts*</P></BODY></HTML> Wed, 22 Aug 2012 16:31:04 GMT https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034725#M210903 Tarik Admani 2012-08-22T16:31:04Z Re: Reauthenticate by NAC https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034726#M210905 <HTML><HEAD></HEAD><BODY><P> no, I haven't configured floating device. </P></BODY></HTML> Wed, 22 Aug 2012 16:38:00 GMT https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034726#M210905 alex goshtaei 2012-08-22T16:38:00Z Re: Reauthenticate by NAC https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034727#M210907 <HTML><HEAD></HEAD><BODY><P> How about rebooting the NAC appliances. is it going to help and remove old MAC addresses ? </P></BODY></HTML> Wed, 22 Aug 2012 16:38:50 GMT https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034727#M210907 alex goshtaei 2012-08-22T16:38:50Z Re: Reauthenticate by NAC https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034728#M210908 <HTML><HEAD></HEAD><BODY><P>Please check and see if you have any entries configured here:</P><P></P><P><A class="jive-link-external-small" href="http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/412/cas/s_cca.html#wp1040166">http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/412/cas/s_cca.html#wp1040166</A></P><P></P><P>Thanks,</P><P></P><P>Tarik Admani <BR />*Please rate helpful posts*</P></BODY></HTML> Wed, 22 Aug 2012 16:40:40 GMT https://community.cisco.com/t5/network-access-control/reauthenticate-by-nac/m-p/2034728#M210908 Tarik Admani 2012-08-22T16:40:40Z
