I don't share your pessimism. First of all, the significant
changes to SNMP and SMI that didn't happen in the EOS and SMING
WGs would have taken years to finish and deploy. Also, I
don't understand why "fixing" SNMP is so important anyway.
The industry has decided SNMP is good for monitoring and
notifications, and it does a great job in both cases. I don't
see any compelling need to make significant changes to
the SMI or SNMP for these tasks. I think SNMP applications
will coexist with NETCONF applications for many years to come.
