Issue

Sometimes customers need to configure a second network interface, for example when the administration network and the log collection network are located in different subnets. An example of configuration could be the following one:

       Interface            : em1
       IPADDR               : 172.30.0.50
       NETMASK              : 255.255.0.0
       GATEWAY              : 172.30.0.1
       Default gateway?     : Yes
       MACADDRESS           : ec:f4:bb:ee:73:3c

       Note: The em1 interface is always used for communication between the Netwitness appliances.

       Interface            : em2
       IPADDR               : 192.168.30.50
       NETMASK              : 255.255.255.0
       GATEWAY              : 192.168.30.1
       MACADDRESS           : ec:f4:bb:ee:af:fc
