How To Monitor A Router/Switch

This document describes how you can monitor the status of network switches and routers. Some cheaper "unmanaged" switches and hubs don't have IP addresses and are essentially invisible on your network, so there's not any way to monitor them. More expensive switches and routers have addresses assigned to them and can be monitored by pinging them or using SNMP to query status information.
