Re: [IPFIX] No active/inactive timeout definitions in any IPFIX RFCs? Idle versus inactive terminology? (part of draft-ietf-bmwg-ipflow-meth-09 review)

Hi Benoit,

The parameter was always called inactive timeout in IPFIX MIB. 
ipfix-config changed from idleTimeout to inactiveTimeout in 
draft-ietf-ipfix-configuration-model-02 to be consistent with the MIB.

We could change the name in the MIB and in ipfix-config if consistency 
is important.
