eenpahlefi, have you tried checking oids .1.3.6.1.4.1.14988.1.1.19.1.1.9 and .1.3.6.1.4.1.14988.1.1.19.1.1.10 ?

@eenpahlefi is obvious, you do not have selected subtree but specific oid

No hints on what devices you both are talking about, on my CCR1036-12G-4S i have same OIDs:

1st / sfp1:
.3.6.1.4.1.14988.1.1.19.1.1.9.1
iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrOptical.mtxrOpticalTable.mtxrOpticalTableEntry.mtxrOpticalTxPower.1
.3.6.1.4.1.14988.1.1.19.1.1.10.1
iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrOptical.mtxrOpticalTable.mtxrOpticalTableEntry.mtxrOpticalRxPower.1

[…]

4th / sfp4:
.3.6.1.4.1.14988.1.1.19.1.1.9.4
iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrOptical.mtxrOpticalTable.mtxrOpticalTableEntry.mtxrOpticalTxPower.4
.3.6.1.4.1.14988.1.1.19.1.1.10.4
iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrOptical.mtxrOpticalTable.mtxrOpticalTableEntry.mtxrOpticalRxPower.4

I’m sorry, I’m just learning sir

iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrOptical.mtxrOpticalTable.mtxrOpticalTableEntry.mtxrOpticalRxPower.2

@eenpahlefi, do not ask “sorry”, no one born with knowledge, and no one can stop learning

Hi,

I know this is set as solved, so sorry for posting it here.

I have a CSS326 running SwOS 2.13 and I queried it like:

/tool snmp-walk <IP-of-the-device>  oid=1.3.6.1.4.1.14988.1.1 community=public

Columns: OID, TYPE, VALUE
OID                                TYPE          VALUE     
1.3.6.1.4.1.14988.1.1.3.11.0       integer       600       
1.3.6.1.4.1.14988.1.1.19.1.1.2.25  octet-string  Telus     
1.3.6.1.4.1.14988.1.1.19.1.1.2.26  octet-string  NASCoxa   
1.3.6.1.4.1.14988.1.1.19.1.1.5.25  gauge         131000    
1.3.6.1.4.1.14988.1.1.19.1.1.5.26  gauge         0         
1.3.6.1.4.1.14988.1.1.19.1.1.6.25  gauge         37        
1.3.6.1.4.1.14988.1.1.19.1.1.6.26  gauge         4294967168
1.3.6.1.4.1.14988.1.1.19.1.1.7.25  gauge         3300      
1.3.6.1.4.1.14988.1.1.19.1.1.7.26  gauge         0         
1.3.6.1.4.1.14988.1.1.19.1.1.8.25  gauge         9         
1.3.6.1.4.1.14988.1.1.19.1.1.8.26  gauge         0

Notice how there is no information about TX/RX power (.9 and .10). However, I can see these information in the web console:

I guess the SwOS 2.13 has no such information available via SNMP, but I could not confirm this through my search in Google. Seems like I am the only one who wants to monitor SFP tx/rx using a switch instead of a router

Does anyone have any further info?

thanks a lot,
Jose
