[c-nsp] SNMP question

[Sam Stickland]

Can anyone answer this question from a college of mine?

"Afternoon all. Does anyone know anything about the minimum poll period 
for an OID on a Cisco box? For example, I'm polling a 6500 for the in 
and out octets for a layer 2 interface and I periodically get a response 
of 0. Even with a period of 5 seconds this still happens. I know that 
this isn't a true reading of the in/out octets as the port connects to a 
market-data firewall which is continuously streaming market -data.
 
Presumably it's a function of the H/W platform and/or the OS but I've 
never been able to find any documentation on this. If anyone can shed 
any light on this - oh so fascinating subject - I would be most grateful."
 
Thanks,

Sam
