There were some of us that were tried to get SNMP to
change so that SNMP Set would be relatively implementable.
The 'gumball machine effect' in SNMP, and the lack of complex data
structures in SMIv2, made distributed control tables a nightmare
to code in the agent.  CLI accepts 1 command at a time. SNMP
accepts an arbitrary number of leafs from an arbitrary number
of commands, and reconstructs commands as they arrive in Set PDUs.

Something as dirt-simple in NETCONF as <make-toast> is a nest of kludges
in SNMP.

For awhile, many OPS people did not really believe operators when
they said they liked CLI because they could read it.  Think OID.
Then go as far in the opposite direction as possible.  Some of the
many benefits of XML -- it can be read, cut-and-pasted, and emailed.

But we don't need to replay the XMLCONF discussions that led to
the formation of the NETCONF WG.  SMIv2 action knob --> NETCONF <rpc>.
End of problem (for now).
