# Dell Force S-Series by SNMP

## Overview

These high performance and low latency Gigabit Ethernet switches deliver the critical functionality that advanced data center network edges demand.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Dell Force S-Series

## 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.
