DDM Port X optic module RX power exceeded the low warning/alarm threshold

One day, one of the DES-3200-28 B1 switches began to write the following in the logs:

Netis WF2780 Firmware Update

For the test, I will update the firmware on the Netis WF2780 router with firmware version V2.1.42494, at the time of writing, on the official website I found firmware version V2.2.43243.

Firmware update BDCOM P36xx EPON OLT

I will give an example of updating the firmware of BDCOM P36xx EPON OLT, we will definitely look at the OLT model, as it can be P36xx or P36xxB.

How to restore BDCOM OLT configuration

Suppose you want to restore the BDCOM OLT configuration from a previously made backup.

BDCOM OLT Recovery

Once an incorrect firmware was loaded into one of the OLTs, because of this, it cyclically rebooted.

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.

Configuring DHCP Snooping on Edge-core

Let me give you an example of setting up DHCP Snooping on Edge-core switches, for the test I’ll take the ES3526XA model.

BDCOM OLT: LLID sequences have been used up on EPON

One day, a technician connected a client and informed me that the ONU is not registering with one of the BDCOM P3608-2TE EPON OLT. I looked at the logs:

Configuring Edge-core ES3526XA

In the test, I’ll configure the Edge-core ES3526XA switch.

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.
