David, If I wanted to add a second VLAN I would do:
Ip flow-export source vlan11 etc.. Once I do that it adds it as a second 'source.' I want to be able to monitor the 6509 with all VLANS and have it read as once source, because I am only licensed for 5 sources, however a source is considered a router/switch, but when I set this up with the VLAN's as above, they come in as separate sources. Is there another way to do it that I am missing?

You also don't need it to be a loopback. If you have a loopback, then it's a good choice to use. But you don't need to create one just for this. All this command does is tell IOS what source address to use in outgoing netflow data packets. You could probably get away with not specify it at all, but then there is a chance that unrelated configuration changes would affect your netflow exports. -David Mitchell Travis Formoso wrote: > Greg, > > We are not running IOS-XR, however this is almost the same and I can > set this up. > > With the loopback0 interface setup what are the commands I need to > run, so that I am monitoring this device correctly with netflow?
