You could also use whatever IP interface you use to manage the device with. You'll need some sort of routing (dynamic or otherwise) pointing routes for your loopback address at your 6509, so unless you already have dynamic routing setup, I would recommend using a port just for management traffic? Depending on the supervisor module you have, there may be a built-in interface on there that wont burn up any ports on your linecards. > What should the loopback interface look like? > > Also once I set it to this loopback I will not need to export to the > VLAN's as this would monitor all the ports? Netflow summarizes some of the traffic flows in a hardware table. Most basically, the "export" process of this is just to package up binary descriptions of this table's contents and put them in UDP packets fired off at a configurable receiver to process these exported flow table entries. So, if you're using a loopback source, you can export flows for all the interfaces on your router from a single source. That way, you can re-configure customer VLANs at will without interrupting your flow exports.
