It can not be done using SNMP or other means. The only way to do some
sort of accounting on VE interfaces is using sFlow.

Hello Cliff,

Thanks for your reply. Just found the answer in the archives too.

It is absolutely unbelievable that this feature isn't being supported yet by
foundry. I mean hey almost every Cisco box can do it and this is really
essential for accounting purposes using mrtg.

What does foundry say? Is there some kind of roadmap?

Best regards,
Gunther

Hi Gunther,

I've spoken to Foundry engineers on this and they tell me it's a hardware
limitation of the BigIron's, and it can't be fixed in software.

per vlan traffic stats is not a standard feature in most platforms using
asic/cam switching paths
