I don't think NetFlow is supported under the old Cisco Catalyst 5505. Can you please tell us the guide that says so?

Hello Alejandro,

I did it on C6500 CatOS.

You need to configure Multi layer switching and to export data from the NFFC to the external collector.

Configuring it on the routing card is not effecitve

see the section called NDE

set mls nde enable

Hope to help

Hello Alejandro,

verify if the current c5505 supervisor, routing engine and other cards support MLS because there are some chassis that cannot and I think they cannot perform netflow accounting too

for example the following device cannot perform MLS

Hello Giuseppe,

could you send some command how to check if supervisor and/or line card supports MLS?

Kind regards,

Jan

If you have a supervisor II card with a nffc card and a RSM it supports mls . MLS has to be configured though on the box in order to utilize the fast switching functions of mls. We used 5500's with mls running for years as our distibution routers. To configure mls go here http://www.cisco.com/en/US/docs/switches/lan/catalyst5000/catos/4.5/configuration/guide/mls.html . To configure netflow on the 5500 go here , http://www.cisco.com/en/US/docs/switches/lan/catalyst5000/catos/4.5/configuration/guide/nde.html . I believe you have to have mls configured on the 5500 for netflow to work correctly. If you do a "show mls entry" and there is nothing in the table then it is not configured. MLS switching greatly speeds up data transfer on a 5500 otherwise anything that has to be routed has to go up and hit the RSM cpu where as if mls is configured the first packet hits the cpu and everything else in that flow is then hardware switched at the layer 2 level which is much faster.
