Configuring Zabbix SNMP Traps

Suppose we configured snmp according to my instructions:
Configuring SNMP Traps on Linux
Now change the configuration file /etc/snmp/snmptt.conf.

IPTables rules for SNMP

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.

Configuring SNMP Traps on Linux

Here is an example of installing SNMP and catching SNMP traps in Ubuntu Server.

Adding BDCOM OLT on ABillS

In this article I will give an example of adding BDCOM-P3310C and BDCOM-P3310B to the ABillS billing system on the Ubuntu Server 16.04 operating system.

List of SNMP OID for FoxGate switches

I’ll write below a few popular SNMP OIDs for FoxGate switches.

CPU usage:

OID and MIB list for PBI tuners

For example, I will use PBI DCH-1400P.

How to solve the error “Unknown Object Identifier (Index out of range: XXX (ifIndex))”

Once I made a Zabbix template for drawing traffic graphs from GPON ports on Huawei SmartAX MA5683T.

From Linux, I looked at the interface indexes with the command:

Huawei S2300 Switch SNMP OID List

I will give a list of some popular SNMP OID and MIB for the Huawei S2300 series of switches and the like.
I will use Huawei Quidway S2326TP-EI for the test.

SNMP OID and MIB for Mimosa devices

I once did a Zabbix template for Mimosa B5c and explored several useful SNMP OID/MIB.

First we will enable SNMP in the device, check the connection from Linux and see the available OIDs:

Configuring SNMP Traps on D-Link Switches

I will give an example of setting up SNMP Traps sending on D-Link switches.
For example, I will take the switches D-Link DES-3200-x:

Create an SNMP password:

create snmp community public view CommunityView read_only

We indicate which host and with which password the traps should be sent:

create snmp host x.x.x.x v2c public

We indicate the change in the state of which ports to send traps:

config snmp link_traps ports 01-24 disable
config snmp link_traps ports 25-26 enable

Check the configuration of sending snmp traps with the command:

show snmp traps

Check the configuration of sending snmp traps on the status of ports with the command:

show snmp traps link_traps

At the end of the command, you can digitize port numbers.
