2Overview

This document describes the steps for installing the Cisco 1811 and the Cisco 1812 integrated services routers. The Cisco 1811 and Cisco 1812 routers are fixed-configuration routers. They each include an integrated 8-port 10/100-Mbps Ethernet switch, two onboard Fast Ethernet WAN ports, two dual USB 2.0 ports, and optional 802.11a/b/g wireless LAN support. The switch ports and the onboard 10/100-Mbps Ethernet ports support 802.1Q virtual LAN (VLAN) encapsulation and enable you to configure demilitarized zones (DMZs), using VLANs and Cisco IOS firewall features. The switch ports are also optionally upgradable to include inline power support for IP phones.
