Not sure which resources you used to configure this, but this looks like Cisco ACS server, so "Generic AAA server" will cause us to parse logs from this device wrong on MARS.
Follow this guide to add the ACS server to MARS:
http://www.cisco.com/en/US/docs/security/security_management/cs-mars/6.0/device/configuration/guide/cfgAaaSv.html#wp914530
There is also a section in here on bootstrapping your ACS for MARS:
http://www.cisco.com/en/US/docs/security/security_management/cs-mars/6.0/device/configuration/guide/cfgAaaSv.html#wp914530
Make sure you have done both the above. You might even want to start over with everything you have done thus far.
