I don't claim to be an expert on cable modems. My understanding is
that the usual operation of cable modems is as specified by DOCSIS.
Admiting that I don't have the most current documentation, the
August 29, 2001 Operations Support System Interface Specification
(SP-OSSIv1.1-I04-010829) contains this on page 30:
During initialization, a CM communicates with a DHCP Server that
provides the CM with its assigned IP address and, in addition,
provides a pointer to the TFTP Server that stores the assigned
CM Config File for that CM. The CM reads the CM Config File and
forwards the set of Service Flow definitions (using SCNs) up to
My interpretation (maybe there is a clearer quote) is that DOCSIS
configuration is performed through Dynamic Host Configuration Protocol
(DHCP) and Trivial File Transfer Protocol, not SNMP. This document
specifies in detail how SNMP is configured along with other things
through these protocols. So, cable modems are an example where SNMP
is NOT used in practice for configuration.
I know even less about RMON probes, but since RMON is a creature of
SNMP, its configuration through SNMP would constitute configuring SNMP
features through SNMP, not configuring the network through SNMP.

We agree on the need for smart people with shared goals to invent
configuration solutions for networks. Randy is trying to gather and
organize the perspective of operators in a fresh start on this effort.
My impression is that there is not a Current Best Practice for network
configuration to be documented. Instead, there are lots of creative ideas.
Don't know who you see as a sales agent.
I am not making unsupported claims, just asking for actual instances of
the practice of configuring through SNMP.
