good day EE,

i recently upgrade a few switches to a new IOS that supports net flow export to scrutinizer. i have successfully enabled it on a few routers and ASA devices. I need to get the switches exporting net flow as well, but i am having a bit of a problem with the commands. since these switches are layer 3 switches i have been able to successfully run the following commands:

ip flow-export source Gi1/0/49 (i also tried interface VLAN1)
ip flow-export version 5
ip flow-export destination 10.1.1.16 2055


these commands were successfuly on a 1941 router, but not working in with the L3 switches. does anyone know if there are switch specific commands i need to input to get it talking to scrutinzer?

any help is definitely appreciated, thanks EE!

The 3750G does not support Netflow export, sorry to say.

so even though these commands ran successfully and the image that's on them now supports net flow, the switch it's self does not, is it safe to say that?

I'd feel perfectly safe saying that. If you don't trust me, check with Cisco.

trust is not an issue, i thought the same but needed to hear it from someone who had a bit more experience with these models. I appreciate your help.
