QSFP optics are not discovered for these devices. Definition is present in Timetra-port-mib and its called tmnxDDMLaneEntry

here is an example

snmpbulkwalk -v2c -c public -OQUs -m TIMETRA-PORT-MIB -M /home/librenms/mibs:/home/librenms/mibs/nokia:/home/librenms/mibs/timos tmnxDDMLaneEntry

Output snippet:

tmnxDDMLaneTxOutputPower.1.1610899520.1 = 8912
tmnxDDMLaneTxOutputPower.1.1610899520.2 = 7580
tmnxDDMLaneTxOutputPower.1.1610899520.3 = 8076
tmnxDDMLaneTxOutputPower.1.1610899520.4 = 8709

Here is the complete OID for Lane 1 TX power where 1610899520 is ifIndex


I’v managed to add it as custom OID but it would be nice to have it as part of OS
