# Cisco SD-WAN by HTTP

## Overview

This template is designed for the effortless deployment of Cisco SD-WAN monitoring by Zabbix via HTTP and doesn't require any external scripts.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Cisco SD-WAN 20.6.0

## 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

1. Put your username and password from Cisco SD-WAN vManage into {$SDWAN.API.USERNAME} and {$SDWAN.API.PASSWORD} macros.
2. Set your Cisco SD-WAN vManage URL as {$SDWAN.API.URL} macro value.

**NOTES**

  The Cisco SD-WAN API token will be generated automatically by the Authentication item every {$SDWAN.AUTH.FREQUENCY}. 
  Don't change the {$SDWAN.AUTH.FREQUENCY} macro value if it's not required.

  The generated Cisco SD-WAN API token and the session ID will be used in all Cisco SD-WAN templates and items.
  These values will be kept in {$SDWAN.AUTH.TOKEN} and {$SDWAN.AUTH.SESSION} macros of each discovered host.

**IMPORTANT**

  Values of {$SDWAN.AUTH.TOKEN} and {$SDWAN.AUTH.SESSION} macros are stored as plain (not secret) text by default.

>Please, refer to the [vendor documentation](https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/cisco-sd-wan-API-cross-site-request-forgery-prevention.html) about the Cisco SD-WAN REST API Token-Based Authentication.
