I use MRTG to monitor 6509 Gigabit ports and I see fairly signigicant traffic on some of my graphs. In particular, there is a lot of traffic outbound from the switch to the backup server overnight. Sometimes this will exceed 300 Megabits/second for over an hour. I am using SNMP version 2 and the switch is in hybrid mode CatOS 6.3(10).

Oh the Fun a newbie can have. The reason you don't see much information is because once the path is established, the bytes passed are not reported to snmp (I think). I'm betting the backplane is where most of the traffic is getting routed. As for the number of vpn users, you can easily write an external script that collects the information and stores it in an mrtg archive. Paul >>> "Moses Hernandez" <[EMAIL PROTECTED]> 08/31/04 7:38 AM >>> Hello listers. I am a new MRTG user and I must say I'm hooked on the product. Great stuff. Anyway I have a few questions and I hope that I can provide enough info so that I can get real good insight. I have started using mrtg on a win32 test box. It has been running for 5 days on the core router 6500 router side, two remote connect routers and the internet firewall. Today I configured the 6500 gigabit switchports to also get snmp info. I have noticed not much traffic above the 640.0 K usage, maybe 1.2M. I am using mrtg 2.10.15 and I thought it was a versioning issue but noticed some others in the archive had similar issues though no resolution. As an aside the low numbers are showing up on my nokia firewalls and the numbers are kind of inconsistance with the bandwidth stats from my isp. Thoughts or comments much welcomed! Upcomming I am trying to figure how I can track amount of vpn users logging into my checkpoint ng ai and amount of vpn traffic.
