Oracle SBCs comes with two local factory accounts for access: user and admin which are authenticated locally, but Net-Net OS offers to have users authenticated using RADIUS or TACACS+.

Having different accounts authenticated via external authentication actually help to have a better record on changes made which actually can be found in cli.audit.log, for example:

You can use show logfile cli.audit.log:

In this case the configuration presented integrates the Cisco Identity Services Engine (Cisco ISE configuration is not included):

Important note here, TACACS servers must be reachable from wancom0 or administration interface, make sure you have the proper routing configured if not, you can always use Host-Routes (static routes inserted in the routing table).

SBC was rebooted to apply the configuration, here is the most recent show logfile cli.audit.log showing only a few commands after authentication commands was applied:

This concludes this entry.
