What exactly do you mean by monitor traffic on VLANs on a switch? Are you talking about how much traffic is being passed from one point on a switch to another and just happens to be on a perticular vlan, or are you talking about how much traffic is hitting the management interface of the switch?
You say that you have managed to do it for the whole interface, i.e. interface VLAN1? You can put your management interface on any VLAN you want with the current versions of Cisco code (older versions didn't always support this) and see how much traffic the management interface is getting to it. You can't really monitor traffic on a VLAN level with a 2950. You would need an intelligent RMON Probe on a trunk going to that switch, or monitor a RSM/MSFC interface like Will Saxon said in his message. The 2950 series switch is really an access layer switch, and does not have nearly the features of the 6500s w/ a MSFC to monitor traffic patters and flows.

I manage to do it for the whole interface but I'd like to do it for each different port. I can't find actually the right OID for these. My switch is a Catalyst 2950. Does anybody know if it's possible?
