Hi Abdul,
The OVA has a standard IP address that you will probably have to change. It's an Ubuntu host, so you have to edit the /etc/network/interfaces file and change the IP address settings. You can find the login credentials in the readme file (root/HPERocks). The default IP address is 10.1.254.250. It is also possible that the ethernet adapter name has changed after importing the OVA. In that case you have to change the adapter name in the interfaces file as well. You can find the adapter name by issuing ifconfig -a.
You can consult the configuration guide in the doc folder for guidance on how to configure filtering. Please note that the application works with Comware, Provision and OVS switches.
Once you can reach the host, you can point your browser to the IP address (either http or https) and you can login with the admin/admin user credentials.
Hope this helps.
Kind regards,
Dik
