Once I needed to monitor the optical signal level on the Cisco Nexus C3064PQ-10GX to prevent cable sagging, stretching and signal loss, because in this case the signal deteriorates gradually, usually I monitor the signal on the end equipment, but I came across an old BDCOM 3310B model in which there was no support DDM.Continue reading “Cisco Nexus SNMP OID for Transceiver”
Once I made a template in Zabbix for Juniper MX204 and I will post some SNMP OIDs in this article.Continue reading “SNMP OID for Juniper”
For example, I will configure SNMP on Juniper MX204.Continue reading “Configuring SNMP on Juniper MX”
In this article, I will give an example of SNMP Traps display about Loop Detect in Zabbix.Continue reading “Displaying SNMP Traps about Loop Detect in Zabbix”
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.
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.Continue reading “BDCOM OLT DDM SNMP OID”
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.Continue reading “ABillS. SNMP Port Shift”
Below is a list of possible OIDs and MIBs:Continue reading “UBIQUITI (UBNT) OID’s & MIB’s”
In this article, I will give an example of IPTables rules for SNMP.
Let’s say “iptables -P INPUT DROP” is the default, which is very desirable.
