Hi Team Netpro -
I am in the process of preparing documents regarding the deployment of Netflow version 5 for some 20 sites worldwide . I would like to know what IOS images can support this technology . Currently some of our routers are running the following IOS Images:
(C7200-SPSERVICESK9-M), Version 12.4(6)T, RELEASE SOFTWARE (fc1)
(C2800NM-SPSERVICESK9-M), Version 12.4(6)T, RELEASE SOFTWARE (fc1)
(C3845-SPSERVICESK9-M), Version 12.3(11)T10, RELEASE SOFTWARE (fc4)
(C3825-SPSERVICESK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)
(C7200-IS-M), Version 12.4(7), RELEASE SOFTWARE (fc6)
Do you think we still need an IOS upgrade or not ?
Thank you in advance .
In addition to information provided by previous poster, I do not believe you need to upgrade with the current images you have running, most SPSERVICES k9 images 12.4 versions support netflow.
I also suggest to go over this link as well as the link provided before me.
you may verify in features lookup here in feature navigator http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
another easy way to verify is by typing a question mark at cli without actually entering the command on the routers.
exmaple for this bellow very basic netflow script on a router place a question mark without actual placing command
ip route-cache ?
ip route-cache flow
router(config)#ip flow-export ?
router(config)#ip flow-export version ? <-- should show all the versions supported 1,5,9, etc..
router(config)#ip flow-cache timeout ?
router(config)#ip flow-top-? <--- for top talkers sub-commands
ip flow-export destination
ip flow-export version 5
ip flow-cache timeout active 1
ip flow-cache timeout inactive 15
(C3845-SPSERVICESK9-M), Version 12.3(11)T10, RELEASE SOFTWARE (fc4) < --- this one should also be able to support netflow
PLS rate any helpful post if it helps
