Does anyone know of any plans to incorporate NetFlow capability on a Cisco 3750 (E) type switch. ?
I love this feature on typical routers or high end switches, but does not seem to be an option on the 3750E series.
I'm currently running 12.2(35)SE2, RELEASE SOFTWARE (fc1).
I raised this question about a year ago with Cisco directly. They thought it might be available in a future release. I ask again as it was mentioned in a cisco brochure for the following switches to meet PCI compliance.
Cisco Catalyst 3750, 4500, 6500 and
2900 Series Switches.
Thanks for any help.
Due to Hardware limitation, I don't see this being incorporated in the 3750/3560 line.
These switches are targeted for the access-layer and a that layer, you don't need to examine Layer3 traffic. That's usually done at the aggregation layer.
A software release won't incorporate NetFlow into these switches as NetFlow supported switches is done in hardware to avoid overloading the CPU.
