No more variables left in this MIB View

[gblades]

Recently upgraded our cisco 3750 switches and enabled ipv6 on them. Now two of them are experiencing errors with both of our cacti servers. Strange that its only 2 switches as they all now have identifical IOS version.

Cacti 0.8.7g

When performing a verbose query on the interface stats this is the error I get :-

Code: Select all

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'

Any ideas?

Did you access that switch via SNMPv3?
And are you restricted to limited view?

- Securing Simple Network Management Protocol : Setup SNMP Version 3 - Cisco Systems

This is the command and output showing you cannot get the Cisco Local System group using user usertwo:

NMSPrompt 99 % snmpwalk -v3 -n "" -u usertwo -l noAuthNoPriv clumsy .1.3.6.1.4.1.9.2.1

Module SNMPV2-TC not found
enterprises.9.2.1 = No more variables left in this MIB View

The only view I have defined is 'snmp-server view remoteping ciscoPingMIB included' which just gives write access so nagios can perform a remote ping from the switch in order to check connectivity over specific interfaces.

Querying is done via v2c. I have performed a diff between the two switch configs and apart from teh expected interface differences the snmp configuration is identical between the working and non working switch.

Hmm.. that's odd.
Somehow ifOperStatus (actual port state) is retrieved successfully,

Code: Select all

+ Located input field 'ifOperStatus' [walk]
+ Executing SNMP walk for data @ '.1.3.6.1.2.1.2.2.1.8'
+ Found item [ifOperStatus='Testing'] index: 8 [from value]

but it denotes "testing".
Is this the same as working switch?

I tried doing a snmpwalk from just .1.3.6 which worked on one switch but gave the same error on the other on.
From that its oviously not a cacti incompatibility with the features configured on the switch but something wrong with the switch config.

I have raised a ticket with cisco and I will let you know what they do to fix it just incase someone else with the same problem finds this topic.

Did cisco ever give you a reason for why this is happening?
