# Brocade FC by SNMP

## Overview

https://community.brocade.com/dtscp75322/attachments/dtscp75322/fibre/25235/1/FOS_MIB_Reference_v740.pdf

### Known Issues
- Description: no IF-MIB::ifAlias is available
   - version: v6.3.1c, v7.0.0c,  v7.4.1c

## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- Brocade 6520 v7.4.1c
- Brocade 300 v7.0.0c
- Brocade BL 5480 v6.3.1c

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.2/manual/config/templates_out_of_the_box) section.

## Setup

Refer to the vendor documentation.
