# Brocade_Foundry Nonstackable by SNMP

## Overview

For devices(old Foundry devices, MLXe and so on) that doesn't support Stackable SNMP Tables: snChasFan2Table, snChasPwrSupply2Table,snAgentTemp2Table -
FOUNDRY-SN-AGENT-MIB::snChasFanTable, snChasPwrSupplyTable,snAgentTempTable are used instead.
For example:
The objects in table snChasPwrSupply2Table is not supported on the NetIron and the FastIron SX devices.
snChasFan2Table is not supported on the NetIron devices.
snAgentTemp2Table is not supported on old versions of MLXe.

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- Brocade MLXe (System Mode: MLX), IronWare Version V5.4.0eT163 Compiled on Oct 30 2013 at 16:40:24 labeled as V5.4.00e
- Foundry FLS648 Foundry Networks, Inc. FLS648, IronWare Version 04.1.00bT7e1 Compiled on Feb 29 2008 at 21:35:28 labeled as FGS04100b

## 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.

# Brocade_Foundry Stackable by SNMP

## Overview

For devices(most of the IronWare Brocade devices) that support Stackable SNMP Tables in FOUNDRY-SN-AGENT-MIB: snChasFan2Table, snChasPwrSupply2Table,snAgentTemp2Table - so objects from all Stack members are provided.

## Requirements

Zabbix version: 7.4 and higher.
