Configuring Cisco routers isn’t hard if you don’t know how to use interface commands. Let’s face it, you have to know commands like no shutdown, ip address, description, bandwidth, and access-group.
In my new article, I discuss all of these commands in detail with configuration examples. Read the full article at: Cisco administration 101: Five interface commands you should know

Software license compliance is critical in IT Departments today. After all, you don’t want your company to get into legal trouble over mismanagement of licenses, do you? To help you out, Cisco has something to make your life easier.
Did you know that Cisco offers a free device inventory, license inventory, and license/feature deployment software application? Registered Cisco users can download this application for free from Cisco.

In my blog post “Sadly, the PIX Firewall Is Discontinued,” written early in 2008, I said how much I had enjoyed working with the Cisco PIX over the years and how disappointed I was that it was announced by Cisco to be “End of Sale” on January 28, 2008.
Now, you can easily migrate your PIX configurations to ASA configuration for your new devices. Find out how to do it, step by step, in my new articleL Converting from old to new with the PIX to ASA Migration Tool

What is your firewall of choice? What firewall do you really use?
Cisco has launched a new addition to their ASA firewall lineup - the new ASA 5580.
However, this new firewall is only for the lucky few that can afford it. You see, the 5580 comes in 3 flavors, the 5580-20, the 5580-20VPN, and the 5580-40. The 5580-20 starts at around $50,000 and the 5580-40 starts around $100,000. So, you see, most of us out there aren’t going to get to have a new 5580 anytime soon (if you have one, let me know because I would like to
“demo it”).
At my company, we tried a PIX 515 but it just lacked the full “unified threat management (UTM)” approach. In other words, it didn’t have anti-virus & content filtering and, when compared to other alternatives, it just wasn’t easy to use. We ended up settling on a Fortinet 100 because it does anti-virus, content filtering, and the GUI is so simple to use. The content filtering was the real savings. While a PIX could use a 3rd party content filtering service like websense, that type of service was going to cost us like $25K per year. With the Fortinet and their Fortiguard service, the cost is only a few thousand per year.
Recently for testing, I bought a Cisco ASA5510. While it is an improvement over the PIX, without the proper module, it can’t do the “anti-X” and the content filtering is still an extra charge.
