ZYXEL MGS-3712F by SNMP

Overview

https://service-provider.zyxel.com/global/en/products/carrier-and-access-switches/access-switches/mgs-3712f

Known Issues

Description: Incorrect handling of SNMP bulk requests. Disable the use of bulk requests in the SNMP interface settings. Version: all versions firmware Device: ZYXEL MGS-3712F

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • ZYXEL MGS-3712F V3.90(BBB.5)_2019.9.23

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Refer to the vendor documentation.

Macros used

Name Description Default
{$ZYXEL.LLD.FILTER.IF.CONTROL.MATCHES}

Triggers will be created only for interfaces whose description contains the value of this macro

 CHANGE_IF_NEEDED

ZYXEL MGS-3712F: Port {#SNMPINDEX}: Link down

This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'eternal off' interfaces.)

WARNING: if closed manually - it will not fire again on the next poll, because of .diff.
