[j-nsp] Junos SNMPv3 Daemon Issue

[Mark Tinka]

Hi all.

Has anyone else ever seen an issue where the SNMPv3 service 
on Juniper devices suddenly forgets the password(s) you were 
using for MD5, DES56 or both?

Jan  6 15:30:01.900 2014  hostname snmpd[1107]: 
%DAEMON-4-LIBJSNMP_NS_LOG_WARNING: WARNING: Authentication 
failed for username

The fix, here, is to re-type the passwords and commit, 
again.

In other cases, commiting a separate configuration logs SNMP 
complaining about needing to reconfigured:

Dec 19 09:17:13.599 2013  hostname snmpd[1074]: 
%DAEMON-4-SNMPD_ENGINE_ID_CHANGED: Warning: Local engine ID 
has changed. Passwords for all the users under [edit snmp v3 
usm local-engine] need to be reconfigured.

I've seen these issues from the first day I started using 
Junos (2007), and it's carrying through to current code. I 
think it's time I started looking at what this could be :-).

Anybody know what this? I'm reluctant to open a case with 
JTAC just yet, as we know how well that will go. If I hear 
of other experiences, at least, I might be able to phrase my 
case in a manner that actually yields a result with JTAC 
:-).

Cheers,

Mark.
