[network::cisco::standard::snmp::plugin] --mode=environment: CRITICAL: Sensor 'TenGigabitEthernet2/1 Receive Power Sensor/2115' is -40 dBm

[joschi99]

There are CRITICALS and WARNINGS because the device has some FC module (GBIC) without a connection:

As you can see there are 2 sensors, one for Transmit Power and one for Receive Power:

sensor 'TenGigabitEthernet2/1 Transmit Power Sensor' status is 'unavailable' [instance: 2097] [value: 0 dBm]
sensor 'TenGigabitEthernet2/1 Receive Power Sensor' status is 'ok' [instance: 2115] [value: -40 dBm]

0 dBm and -40dBm because no FC is attached at the moment. Instance 2097 is also unavailable because customer shut down it.

Cisco is returning thresholds for both:

'sensor.dBm_TenGigabitEthernet2/1 Transmit Power Sensor'=0dBm;-7.2:-1.1;-11.2:2.8;; 
'sensor.dBm_TenGigabitEthernet2/1 Receive Power Sensor'=-40dBm;-9.8:-1.1;-13.8:2.8;; '

but this thresholds are only valid if the interfaces will be used/active.

We have this issue on every Cisco device where FC is not attached. Could you try to handle this exception?

[garnier-quentin]

Yes i know. It's a old issue. But i dont know how to fix it. It's not easy to link with the interface down.

[joschi99]

I understand. To handle the exception in this way is to simple?

• if "transmit power" = 0 dBm then OK
• if "Receive power" = -40 dBm then OK

[joschi99]

Have done some test: --list-interfaces will return the status of all interfaces like:

It should possible to connect this information with the sensor using interface name?

[garnier-quentin]

Could you provide a full snmpwalk ?

[joschi99]

cisco-fiber.zip could you remove the file when you have downloaded it?

[joschi99]

are there some news on this?

[lucie-dubrunfaut]

Hello :)

This issue seems old and I'm not sure we provided an answer around it isn't it? Can you tell me if you still encounter this issue? Thank you for your understanding.

[joschi99]

Yes, this issue is still there and should be handled. How can I help you?

[lucie-dubrunfaut]

Hello :)

I have started the procedure internally to correct this problem with the elements you provided to us (including the SNMPWalk if you wish to remove it). I have the necessary information to initiate a troubleshooting, when processing the ticket the person in charge will contact you here if necessary. Thanks for your patience 🙏
