I strongly encourage you to upgrade software to latest 12.1 and enable both 'ip cef' and 'ip route-cache flow' ( and 'ip route-cache policy' if you are using policy routing ) It will give you a negative impact, e.g. it will actually help performance. I have 2 border routers, one 4000 and one 4500, with about 40 gigabytes consumed per 24h so I know what I'm saying ;) -- Paul P 'Stingray' Komkoff Jr // http://stingr.net/key <- my pgp key This message represents the official view of the voices in my head _______________________________________________ Flow-tools mailing list [EMAIL PROTECTED] http://mailman.splintered.net/mailman/listinfo/flow-tools
