Port power management with ASR 9001

Help
1

Hello the community,

I have a question with the port power measurement (bDm value) from the overview panel.

This problem occur with Cisco ASR 9001 routers with IOS XR 5.3.3 and satelite connected to it.

In the overview area we can see the bDm value for the 10Gig integrated interfaces.
But there is no value measured for the 1Gig ports of the satelite routers.

Generally, all this 1Gig ports are correctly seen and monitored by LibreNMS for this equipment.

Does LibreNMS can only monitor the power of integrated interfaces ?
Maybe I missed a parameter somewhere ?

Thanks a lot

Regards

Nicolas

1Gig copper ports? Are you sure they should be showing dBm values…

No it’s Fiber ports with Bi-Directionnal SFP.

Pastebin the output of ./discovery.php -h HOSTNAME -d -m sensors - I expect the device isn’t returning the info from snmp.

You haven’t run the command correctly.

Ok, my bad … i made a mistake in the hostname.

This is the right output :

What’s the interface for the 1Gb port? GiX/X/X?

9

Yes, especially

Gi101/0/0/0 to Gi101/0/0/43
Gi102/0/0/0 to Gi102/0/0/43
Gi103/0/0/0 to Gi103/0/0/43

I don’t see those mentioned in the output so unless they are under different names it looks like that data isn’t sent back from your device.

Hi Iaf,

The problem was in the Cisco router directly.
My SNMP community wasn’t belong to the “sysowner” group.

Now the values are correctly seen.
