Help regarding IPV6 : NPM 10.2 showing ipv6 virtual interface in DOWN STATE !! But showing data and graph !!

Hello All,

We are evaluating NPM 10.2 to monitor our ipv6 environment. The problem is that NPM is showing IPV6 virtual interface in DOWN State but showing its data and graph .

Why it is coming in DOWN state and how we can turn it to UP state ??

Hi,

The overall status is simply reflecting the Operational Status since the Administrative Status is Up.

The device is most likely telling NPM that the interface is Down in the IF-MIB. However, this status does not prevent NPM from gathering other statistics. So if the device is mistakenly reporting the interface as down when there is actually traffic going across it, then NPM will show both the Down status and the traffic.

This could be an issue with the device as we don't typically see this type of behavior. You should contact your sales rep so he can have a sales engineer look at your install and perhaps get an SNMP walk for development if necessary.

Also, checking the operational status with some SNMP tool like the Engineer's Toolset SNMP MIB Browser would tell you if the device is reporting the Operational Status as Down.

Thanks

If you want, you can disable garthering statistics from DOWN interfaces:

1) go to <Orion install directory>\NPM\

2) open file "SolarWinds.NPM.Collector.dll.config" for editing

3) change row <add key="ProcessDownInterfaces" value="True" /> to <add key="ProcessDownInterfaces" value="False" />

4) save file

5) restart Orion services

Hello All,

Thanks for your reply.

The device is Huawei NE80e.

If i run display ip interface brief command on router than it shows the status of the interface as ADMIN = UP , OPERATIONAL = DOWN.

But if i run display ipv6 interface brief than interface status is ADMIN = UP and OPERTIONAL = UP.

So i think NPM is by default taking status with display ip interface brief and that's why it is showing operational status = down.

So what should i do now ? monitoring IPV6 is become core requirement for us.

We are polling ifTable mib for both IPv4 and IPv6 interfaces.

Please, open support ticket and send SNMP walk of the device. For the SNMP walk use <Orion install directory>\SnmpWalk.exe tool.

Thanks

Hello Michal,

To get SNMPWALK of my router I put 1 in ROOT OID and start scan , and now its is continuously scanning from last 12 hours, so far it has scan 1454000 OIDs and still running.

Is it normal behavior or i have to stop it manually ?
