Strange SNMP problems on GAIA

Hi guys,

since some time (can't tell exactly when it started) we encounter some strange problems with SNMP.

When I do an snmpwalk, it times out after a few hundred lines. Some attempts provide more, some less lines on the same machine.

However, that is not on all machines. E.g. on a cluster one machine answers just fine, the other don't.

All machines are on R80.40. Hardware is Check Point 5800 and Check Point 6200P.

Most of the machines do NOT run VSX.

I made some tests and it looks like every attempt stops around MIB .1.3.6.1.2.1.25.3.2.1.1

There is no special SNMP configuration, and identical on all machines:

set snmp mode default
set snmp agent on
set snmp agent-version v3-Only
add snmp interface Mgmt
add snmp interface bond1
add snmp usm user FWxxxxx security-level authPriv auth-pass-phrase-hashed xxxxxxxx privacy-pass-phrase-hashed xxxxxxxx privacy-protocol DES authentication-protocol MD5
set snmp traps trap authorizationError disable
set snmp traps trap biosFailure disable
set snmp traps trap clusterXLFailover disable
set snmp traps trap coldStart disable
set snmp traps trap configurationChange disable
set snmp traps trap configurationSave disable
set snmp traps trap fanFailure disable
set snmp traps trap highVoltage disable
set snmp traps trap linkUpLinkDown disable
set snmp traps trap lowDiskSpace disable
set snmp traps trap lowVoltage disable
set snmp traps trap overTemperature disable
set snmp traps trap powerSupplyFailure disable
set snmp traps trap raidVolumeState disable
set snmp traps trap vrrpv2AuthFailure disable
set snmp traps trap vrrpv2NewMaster disable
set snmp traps trap vrrpv3NewMaster disable
set snmp traps trap vrrpv3ProtoError disable
set snmp contact "xxxxxxxxx"
set snmp location "xxxxxxxxxx"
set snmp traps advanced coldStart reboot-only off

Strange thing is, on machines, where everything works fine, I get around e.g. 14'000 lines of SNMPWALK, on machines where timeouts occure, sometimes I get above 65'000 or even over 100'000 lines back, before the timeout.

This way, one snmpwalk takes over half an hour...

One of the questions is: Why do I get so much different outputs on similar devices of a cluster?

BTW: Increasing the timeout setting of snmpwalk does not help (it simply takes much longer).

Versions are the same between the machines. E.g.

A while ago everything was fine. We updated to R80.40 from 77.30 in the past, but as far as I see, the problems started a while after that, so I don´t see a correlation here.

Any ideas?

Please let me know, if you need more/special information.

Thanks a lot in advance!

Best regards

Nico

Best to open a TAC case here.

Is there a reason to walk the whole MIB versus get a specific OID?

Hey Nico,

I know this is older sk, but it might be worth checking. TAC case would not hurt either, as it sure sounds like a very peculiar issue.

Well, we use a monitoring software "LibreNMS", which does a discovery every few hours. For such a discovery, it pulls pretty large MIB ranges (if not ALL available), to fill it´s database.

Strange thing is, most of our firewalls do not have any problems with that...

Hi Andy,

thanks for the link, but in fact I already found this sk.

However, we do not have VSX running on most of the machines, which have the problems... So this must be another problem...

Best regards

Nico
