# Aruba CX 8300s by SNMP

## Overview

The Aruba CX 8300 series is designed for core and aggregation in enterprise campus networks as well as top-of-rack/data center environments. These are high-performance fixed switches offering port speeds from 1 GbE up to 100 GbE, with maximum switching capacity up to 6.4 Tbps.


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- Aruba JL636A 8325, Aruba JL717A 8360

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

Refer to the vendor documentation.
