Step 6

Specifying the DNS Settings

The local TCP/IP stack that resides on the appliance uses DNS services just as any host on the network
does. In addition, MARS uses DNS to resolve the IP addresses into hostnames for events that it studies.
This mapping enables you to study events by hostname or by IP address.
To specify the DNS settings for the appliance, follow these steps:
Select Admin > System Setup > Configuration Information.
Step 1
Scroll down past the Device Config group to the DNS Config group.
Step 2
OL-14672-01
