Today I’m starting to upgrade my almost 40 Cisco Catalyst 3560G switches to a newer version of the IOS. Since these switches were installed over the course of about 2 years, a lot of them are running different IOS versions, so it’s time to get everything up to snuff and running the same version across the board. The latest version that’s installed on any of them is 12.2(25) SEE3 and according to Cisco support that version is now in deferral and it’s suggested to move to version 12.2(44) SE5. But…that version is also in deferral so the suggested is 12.2(44) SE6. Now at the time of this writing, the latest version is 12.2.50-SE. But I’m going to stick with version 12.2(44) SE6 for now as I’m not one to jump on the latest version of anything unless I absolutely have to.

April 14th, 2009If you’re managing your Cisco routers, switches, etc. using local accounts created on each device, you need to read this article. Being relatively new to the Cisco IOS myself, I get excited when I find a time saver such as this. It’s one of those things that I knew could be done, but just never took the time to investigate it. What I’m talking about it leveraging Active Directory as the authentication method into the Cisco IOS. So instead of creating and managing user accounts on the Cisco equipment, you can use the existing user accounts in AD. I’ll start by setting up and configuring the Internet Authentication Service, Microsoft’s version of a RADIUS server, in which the Cisco equipment will use to access AD for authentication.

March 30th, 2009
So you have your router and switches all setup the way you want and everything is running smoothly within your network. Then one day it happens. Your router has a hardware failure and needs to be replaced. You expedite the replacement, mount it in the rack, power her up, and then realize that you don’t have a copy of the most recent configuration or worse yet, you don’t have a copy at all!
