Huawei OLT DDM SNMP OID

Once on the highway to one of the Huawei MA5608, due to the heat and a bad cable, the optical level gradually deteriorated until the connection with the device was lost.
Therefore, I created triggers in Zabbix that will report that the signal is getting worse and this will prevent loss of connection.

BDCOM OLT DDM SNMP OID

Once it was necessary to monitor the level of the optical signal to the BDCOM OLT P3310C and P3608-2TE, after the trunk cables of different quality could stretch in the summer, and thus we lost contact with one of the OLT, although this situation could be predicted and prevented.

ABillS. SNMP Port Shift

I noticed once that on Huawei switches SNMP port indices can be shifted, for example, on Huawei s2326 VLANs are considered first, for example ifIndex.1 is vlan1, ifIndex.2, ifIndex.3, ifIndex.4 are user VLANs, and then ifIndex5 is the port Ethernet1. Because of this, when binding client services to switch ports in ABillS, the ports will not be displayed correctly.
