To configure an interface with static network settings using ifcfg files, for an interface with the name eth0, we need to create a file with name ifcfg-eth0 in the /etc/sysconfig/network-scripts/ directory as follows:
1. vi /etc/sysconfig/network-scripts/ifcfg-ens192
2. Add the following information and change the IPADDR, NETMASK and GATEWAY according to environment that the Netflow OVA is deployed ON.
HWADDR=(get MAC address from VM's settings>> Hardware>>Network Adapter>>Advanced)
3, To check the status, please run : service network restart
IMPORANT TIP when adding a NetFlow target : Please make sure that NetFlow is enabled on vCenter switch >> settings>>Monitoring>>Netflow Status and by default the port is 9995. Also, make sure the timezone is consistent between turbonomic server and flow collector by running : timedatectl set-timezone UTC. To verify receiving flow run : nfdump -R /var/netflow ( Also check that the collector IP address on switch is set to Netflow IP address).
Additionally, under /etc/sysconfig/network-scripts/ other than ens192, if there are eth0 or ens10***, move those files to tmp as they are conflict with ens192 settings and restart network.
