# Cisco Expressway Monitoring Guide

## Overview

This guide is designed to assist Nectar Unified Communications Platform (UCMP) users in the monitoring of Cisco Expressway. Cisco Expressway is often deployed as a pair:

- Expressway-C
- Expressway-E

However, it can also function as a standalone Expressway or be used with other systems, such as other Expressways, gatekeepers, and SIP proxies. It can be clustered with up to six Expressways to provide n+1 redundancy and up to four times individual capacity.

### About this Guide

This guide provides instructions that should be performed on each Expressway element in the environment, including how to:

[**Configure Expressway SNMP**](https://support.nectarcorp.com/preview/v1/ae56d60f-c774-44f5-9035-515be480bc6c/1#configure-expressway-snmp)
