Hi, I am not sure what proposal you are referring to. I know multicast SNMP for discovery was proposed quite a few years ago, but multicast SNMP would depend on the non-secure nature of SNMPv1 and a well-known community string. This is at odds with the IETF declaring SNMPv1 Historic and not recommended.
The multicast approach won't work with the built-in SNMPv3 security, and to my knowledge all effort to do this (at least in IETF) was dropped precipitously. Hopefully, nobody is seriously considering this approach again, if it builds on SNMPv1. -- David Harrington Director, Transport Area Internet Engineering Task Force (IETF) [email protected] +1-603-828-1401 On 3/9/12 9:38 AM, "Jim Gettys" <[email protected]> wrote: >On 03/08/2012 11:42 PM, Livingood, Jason wrote: >> >> I think that E2E into the home for SNMP is perhaps one of the >> things that would motivate an ISP to support homenet. >> >> >> E2E network management and/or monitoring, yes.
