How to Install Cisco SDM (Security Device Manager)

What is Cisco SDM?

You typically use CLI (Command Prompt) when configuring a Cisco router. However, if you are not familiar with Cisco commands, you can easily configure your device using the SDM application developed to manage the Router through a web browser.

SDM software is available in two versions. These;

   Express Package

The Express Pack is a package with limited features that allows you to perform more basic operations.

   Full Package

The Full Packet allows you to configure basic and advanced settings for the Cisco router. For example, you can configure LAN and WAN connections, enable VPN, and also configure the Firewall.

In short, you can enable or configure many features using this software. You can use the CLI command prompt when your software is limited.

When you purchase a new router, you can see the SDM Setup CD/DVD among the equipment on the side. Also, on different Cisco models, this software comes preloaded. Java Runtime versions 1.5 or 1.6 are required for installation. The software does not work properly in current Java versions.

Required Programs

First of all, download Cisco SDM V2.5, Java, and Router IOS c3725 image from the following buttons.
