EXA GPON Transceiver RX/TX dBm not accurate

[victorpetrescu]

Hi there,

I’m using a device with the EXA os and I noticed something weird in the values of the Transceivers RX/TX.

As in the picture 1/1/1 to 1/1/4 have the same TX and RX power, which is not true in reality. Gponport 1/1/5 has a different value.

From snmpwalk those are the values for the 5 ports:

SNMPv2-SMI::enterprises.6321.1.2.2.2.1.6.2.1.7.1.1.1 = INTEGER: 19841
SNMPv2-SMI::enterprises.6321.1.2.2.2.1.6.2.1.7.1.1.2 = INTEGER: 20465
SNMPv2-SMI::enterprises.6321.1.2.2.2.1.6.2.1.7.1.1.3 = INTEGER: 19865
SNMPv2-SMI::enterprises.6321.1.2.2.2.1.6.2.1.7.1.1.4 = INTEGER: 18588
SNMPv2-SMI::enterprises.6321.1.2.2.2.1.6.2.1.7.1.1.5 = INTEGER: 34458

Values for Gponport 1/1/1 and Gponport 1/1/5 are correct. But 1/1/2->1/1/4 are the same with 1/1/1.

Thank you !

I also noticed, maybe it’s related, that it cannot discover all the Gponports, namely every port that will pass 1/2/8. For example, starting with 2/1/1 it throws an error.
