Cisco Catalyst – Find out What Port an IP Address is Plugged Into
KB ID 0001022 Problem I networked some gear this afternoon, and I made a mental note of the ports I patched into on the switch. On the way back to the office I got side-tracked. By the time I got back to my desk I could not remember what port I had used, and I wanted to add a description to the port. This is not my server room 🙂 So I knew the IP address but not the port number, how can you find that out? Solution 1. My IP address is...
Cisco Catalyst – Upgrading IOS (via USB)
KB ID 0001056 Problem Had a stack of 3560-X Switches to update today, and when I went looking for the notes I used last time, I could not find them. So This time I took the time to document the procedure.

Connecting to and Configuring Cisco Routers with ‘Cisco Configuration Professional’
KB ID 0000512 Problem It’s not often I work on Cisco routers, but as I tend to do most of the Cisco ASA Firewalls, I’m the unofficial “Cisco Guy”. Which is fine until someone wants a router or some complex switching, then I need to do some heavy duty frowning. Last time I put in a Cisco router it was a baby Cisco 800 series (an 877W) so I assumed the 1921 ISR router I had to put in would be the same. Before I...
