I thought it would be helpful to create a resource page that you can always come to for all of your system and networking needs. The resource provided here is meant for quick and easy implementation, something that you can easily make use of, with minimum customization. Resources include free network tools and resources download. Configuration templates, editable MS Visio network diagrams and tips. If you are looking for step-by-step tutorials and in-depth level documentations, please check out my Knowledge Base page.

Cisco Wireless Controller Configuration

Cisco-wireless-controller (1)

Describes typical wireless system design for a corporate environment. An in-depth, step-by-step tutorial on Cisco Wireless Controller Configuration (WLC) is included. Our configuration example is based on the highly popular Cisco Mobility Express Bundle . Download and import the lab configuration and customize to fit your environment in matter of minutes.

Cisco ASA DMZ Configuration Example

ASA-DMZ

This configuration example walks you through creating two DMZ security levels on a Cisco ASA firewall. The information applies to legacy Cisco ASA 5500s (i.e. ASA 5505, 5510 and 5520) as well as the next-gen ASA 5500-X series firewall appliances.

Since ASA code version 8.3, there was a major change introduced into the NAT functionality by Cisco. We will cover the configuration for both pre-8.3 and current 9.x releases.

Basic Cisco ASA 5506-x Configuration Example

Basic Cisco ASA 5506-x Configuration Example (1)

ASA 5506-X, 5508-X, 5516-X and 5585-X with FirePOWER modules are Cisco’s latest additions to their “next-generation” firewall family. This example covers how to configure basic ACL (Access Control List), Network Address Translation (NAT) and a simple DMZ network hosting WWW server. The equipment used in this example is Cisco ASA 5506-X running code 9.5(2). You do not need to have FirePOWER license to use this configuration template.

BGP Configuration Example for Multi-homed ISP Failover

Automatic ISP failover over uneven bw trans

The configuration example covers automatic ISP failover over uneven bandwidth circuits using HSRP, IP SLA and BGP technologies.  The network is designed so that circuits with higher capacity and cheaper costs are utilized first. We keep the lower bandwidth or/and higher cost circuit as an “active” backup without losing the automatic failover provided by BGP.
