TitleNAC controller shows SNMP Contact Lost in NMS console
In NetSight Console the NAC Appliance shows SNMP Status of Contact Lost and has a red icon
NetSight Console 6.x
There are five SNMPv3 parameters that need to be configured  in the NMS Edit Credentials and in the NAC appliance's /etc/snmp/snmpd.conf file, and they must agree.  If all five do not agree, then the SNMP status will be Connection Lost and the NAC icon will be red.
  • user name
  • authentication type
  • authentication password
  • privacy type
  • privacy password
Make certain the parameters agree in both the Edit Credentials and in the /etc/snmp/snmpd.conf file.

Use the procedure outline in the following article to assign the appropriate SNMP profile to the NAC appliance:
