[f-nsp] Measurement of BigIron virtual interfaces

[Sam Stickland]

Hi,

Is it possible to measure the virtual interface bandwidth stats on the 
BigIrons (Mmgt4)? I notice that the interface OID's appear to be readable 
but the counters never seem to increment (running 07.7.01T53)

Can this information be read via SNMP. If not, a cursorsy glance at the 
sFlow specs seems to suggest is it possible to measure this information 
using sFlow. If so are there any opensource or reasonably lightweight 
tools that can process the information in this regard?

Thanks,

Sam
