Very true - but I have no idea what the contents mean. if NVATTR_2 is "2" for 
ifType that is not the same if it is "2" for ifLocalReason. Yes, blanks are 
detectable, but deciding which format the trap is still won't be easy unless I 
can tell whether its a 3, 4, or 5 type trap. Mind you, all these routers are 
running RECENT versions of IOS - everything is 11.3, 12.0 or higher. We're not 
talking older than dirt, just not most recent. 

Thanks again everyone, the cat skinning will begin soon.
