NTBA - Undocumented CLI features - unknown-interface-flows

Hi,

Software Version    : 8.1.3.10

While going through both the "McAfee Network Security Platform 8.1 - CLI Guide revision B" and "NSP_8_1_NTBA_Administration_Guide_RevD_en-us.pdf",

i can't find documentation for the following command:

unknown-interface-flows

  unknown-interface-flows  unknown-interface-flows variables

> unknown-interface-flows

  ACCEPT  Accept flows with unknown interface also

  REJECT  Reject all unknown interface, Accept flows with known interface only(enabled on NSM)

  STATUS  Show current setting

Does anyone knows what this command is for ?

Re: NTBA - Undocumented CLI features - unknown-interface-flows

"unknown-interface-flows accept" may be useful if you have 3rd party routers sending netflow records to the NTBA.

If you don't have SNMP access to the router or don't want to poll the interfaces, you can use the command on NTBA CLI to accept flows from these devices. By default, this feature is turned off with "unknown-interface-flows reject".

Note that without polling the interfaces from the router, there won't be any indication in the alert records of where this alert came from (you'll probably only get the device). In addition, you have to define your zones by CIDR instead of interface. By default, all hosts will arrive in the default internal zone, so I recommend adding CIDR entries for all of internet on the default outside zone before enabling this.
