# ZYXEL GS-4012F 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 GS-4012F
## Requirements
Zabbix version: 7.0 and higher.
## Tested versions
This template has been tested on:
- ZYXEL GS-4012F V3.90(BBB.5)_2019.9.23
## Configuration
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
## Setup
Refer to the vendor documentation.
