Hello - just looking for some guidance perhaps here?
What would make a Cisco RV220W router fail to provide an "known to be existing" value only when it is queried 'remotely' using SNMPv3 protocol?
It is "known to be existing" because an SNMPv1 (and SNMPv2c) query works fine.
The 'remote' SNMPv3 query seems to gain access but then report that the value does not exist.
I can find no RV220W logging information regarding the remote access attempt - even though DEBUGGING is on ....
Does SNMP slip in without being logged?
ADVthanksANCE,
michael grimes
Summary:
========
We have four (4) similar RV220W routers, each in a different location.
Three of them are responding well to SNMPv3 AuthNoPriv queries.
One gives us a "Timeout (Sub-id not found: ..."
It must be some kind of setting on this "odd" RV220W.
My question is where else might I look.
(1) credentials appear to be same
(2) SNMPv3 configuration seems to be correct (identical configuration works for different RV220W)

$ snmpwalk -v 1 -m ALL -c CRG <<valid-routable-IPadress>> SysLocation
SNMPv2-MIB::sysLocation.0 = STRING: WorcCRG
michael@CRCC-ltMRG /cygdrive/c/users/michael/Downloads
$
{ so above you see that the entry exists }
michael@CRCC-ltMRG /cygdrive/c/users/michael/Downloads
$ snmpwalk -v 3 -m ALL -u cisco -l AuthNoPriv -a MD5 -A <<valid-MD5passphrase>> <<valid-routable-IPaddress>> SysLocation
snmpwalk: Timeout (Sub-id not found: (top) -> SysLocation)

$
{ so above you see that the RV220W complains that the entry does not exist }
Also note that if the same SNMPv3 command is run from 'inside' the RV220W IPsapce we get the same (good) result as if using the SNMPv1 query.
