It likely expired.

The WG has discussed this question a few times and has not reached any consensus.

Here is the summary:

1) many feel that an **SNMP** Agent is not going to fit into constrained devices.
2) Jurgen has demonstrated it does fit into a class 2 device on using
   Contiki.
3) others have pointed out that SNMP is not the only way to deal with a MIB,
   and the important things in a MIB is the set of statistics which one might
   collect, and transmit in *some* way.
4) opinions have ranged from HTTP / CoAP to NetCONF/YANG as other transport
   alternatives to SNMP.

I think that it is simply early for many people to talk about having
consistent sets of statistics... BUT. PLEASE FEEL FREE TO PROVE ME WRONG.

In particular, I think that *some* standard way to get the network adjacency
matrix (as well as the DODAG) out of motes would be very useful for network
operators.
