3560 flow stats - how?
Hello,
I would like to identify flows (like IP accounting) that is L3 switched accross two VLANs on a 3560. Unfortuanly there is no router available in the topology to assist me in this and have to work on the 3560.
How to go about this? IP accounting not supported on SVI (maybe on routed switchport?), relflexive acl gives me flows but not the data being transfered, snmp maybe?
Any alternatives out there? (posted before?? oops, duh)
Thanks

The 3560 doesn't support NetFlow. You need to upgrade to the chassis switches before it gets supported. The 3560 IOS still had some NetFlow commands for some reason the last time I looked but they don't work properly. -

The VLAN actually leeds to MPLS provider, no other option to ask them to turn on ip accounting?

I'd just hang a server off the 3560, put it's NIC in promiscuous mode, run a netflow collector and then configure that port on the switch as a SPAN port.
