New NUT install dealing with three APC Smart-UPS 5000s, two of which
have AP9617 and the third has a AP9619 card.
The SNMPv3 configurations on all three are exactly the same. This is
confirmed by snmpget calls that work just fine:
snmpget -Cf -v3 -u [...] -l authPriv -A '[...]' -X '[...]' -a
MD5 -x DES [upsname] .1.3.6.1.4.1.318.1.1.1.1.1.1.0
snmp-ups can query all three UPSs with SNMPv1 with no problems. However,
querying with SNMPv3 doesn't work if I try to query more than one of them.
SNMPv3 works fine when I have any one of the three configured in
ups.conf while the other two are configured with SNMPv1. It doesn't
matter which _one_ UPS is configured for SNMPv3 in ups.conf, they all
work individually (see below example).
However, if I configure any two or all three of them to use SNMPv3 then
on startup upsdrvctl complains about "unhandled ASN 0x81 received from
.1.3.6.1.4.1.318.1.1.1.9.3.3.1.7.1.1.3" and fails to start.
My current [redacted] ups.conf follows. The only differences between the
values are on the port and desc lines (ignoring #, of course).
[ups1]
desc = "APC Smart-UPS 5000 SNMP in rack 1 - AP9617"
driver = snmp-ups
mibs = apcc
port = [ups1...]
# snmp_version = v1
# community = [xxx]
snmp_version = v3
secLevel = authPriv
secName = [xxx]
authPassword = [xxx]
authProtocol = MD5
privPassword = [xxx]
privProtocol = DES
[ups2]
desc = "APC Smart-UPS 5000 SNMP in rack 2 - AP9619"
driver = snmp-ups
mibs = apcc
port = [ups2...]
snmp_version = v1
community = [xxx]
# snmp_version = v3
# secLevel = authPriv
# secName = [xxx]
# authPassword = [xxx]
# authProtocol = MD5
# privPassword = [xxx]
# privProtocol = DES
[ups3]
desc = "APC Smart-UPS 5000 SNMP in rack 3 - AP9617"
driver = snmp-ups
mibs = apcc
port = [ups3...]
snmp_version = v1
community = [xxx]
# snmp_version = v3
# secLevel = authPriv
# secName = [xxx]
# authPassword = [xxx]
# authProtocol = MD5
# privPassword = [xxx]
# privProtocol = DES
