Analyzing Transceiver Value via SNMP on X590-24x-1q-2c

[alexandersrz]

Hello,

we want to monitor our uplinks to our switches.

Therefore i found the command : “Show port x Transceiver Information Detail”

These are the values i wanted to get via SNMP to monitor them on PRTG.

I have two problems.

The first is that i get different values than i expected.

1.3.6.1.2.1.99.1.1.1.4.192 = „33“ [ASN_INTEGER]  -> temperature

1.3.6.1.2.1.99.1.1.1.4.193 = „3“ [ASN_INTEGER] -> Vcc

1.3.6.1.2.1.99.1.1.1.4.194 = „6“ [ASN_INTEGER] -> TxCurrent

1.3.6.1.2.1.99.1.1.1.4.195 = „5686“ [ASN_INTEGER] -> TxPower , seems like a Problem…

1.3.6.1.2.1.99.1.1.1.4.196 = „-2“ [ASN_INTEGER] -> RxPower

when i Show via cli i get the Right values.. Does somebody know anything?

The second Problem is on my QSFP24 100GB ports. There i have the following values..

1.3.6.1.2.1.99.1.1.1.4.452 = „37“ [ASN_INTEGER] -> Temp

1.3.6.1.2.1.99.1.1.1.4.453 = „3“ [ASN_INTEGER]  -> vcc

1.3.6.1.2.1.99.1.1.1.4.454 = „1“ [ASN_INTEGER]  -> seems like TxPower Channel 1

1.3.6.1.2.1.99.1.1.1.4.455 = „1“ [ASN_INTEGER]  -> seems like TxPower Channel 2

1.3.6.1.2.1.99.1.1.1.4.456 = „1“ [ASN_INTEGER]  -> seems like TxPower Channel 3

1.3.6.1.2.1.99.1.1.1.4.457 = „1“ [ASN_INTEGER]  -> seems like TxPower Channel 4

1.3.6.1.2.1.99.1.1.1.4.458 = „7“ [ASN_INTEGER]  -> seems like Tx Current Channel 1

1.3.6.1.2.1.99.1.1.1.4.459 = „7“ [ASN_INTEGER]  -> seems like Tx Current Channel 2

1.3.6.1.2.1.99.1.1.1.4.460 = „7“ [ASN_INTEGER]  -> seems like Tx Current Channel 3

1.3.6.1.2.1.99.1.1.1.4.461 = „7“ [ASN_INTEGER]  -> seems like Tx Current Channel 4

But where are the RxPower values? at .462 i have no values anymore..

Thanks for helping!

Alex

I am not the SNMP pro, but it could be that the OIDs are not correct or need to be related differently.
I have taken a look at the first OID.
1.3.6.1.2.1.99.1.1.1.4
This value can only be used in conjunction with the values:
1.3.6.1.2.1.99.1.1.1.1
1.3.6.1.2.1.99.1.1.2 and
1.3.6.1.2.1.99.1.1.1.3.
For example, for the value 1.3.6.1.2.1.99.1.1.4 the exponent is set in the following value 1.3.6.1.2.1.99.1.1.2 . This should then probably change the value 1.3.6.1.2.1.99.1.1.4 shown on your cli.
