Uploading CCIE lab configurations & using config replace to save time

This post will contain two major parts; Getting configurations onto Cisco IOS switches via TFTP, and utilizing config replace to replace configurations quickly for different labs. The first part, loading configuration files via TFTP, is really only needed on devices that don't have USB ports such as the 3650 platform.

EVE-NG Default IDLE PC

As I continue on my quest for the perfect lab I have been messing around with EVE-NG (a competitor to GNS3 and VIRL). One thing I really like about EVE-NG is the ability to use a web client instead of needing a thick client like you do for GNS3 and VIRL. A draw back I've … Continue reading EVE-NG Default IDLE PC

This requirement is two fold, I don't feel like always sitting in my basement to build topologies and I'm not always home when I will be studying.

Originally I was planning on utilizing a CSV and the bulk import tool to regularly import new devices into ISE as they were built. This allows … Continue reading Cisco ISE REST API & Python

Hiding (filtering) a specific user from reporting in Cisco ISE

I ran into an interesting problem preparing for an 802.1x deployment - the authentications report in Cisco ISE was full of all the network devices checking to make sure ISE was still available (health checks). As seen below the load balancer's keep alive fill the logs pretty much on their own, imagine trying to troubleshoot a … Continue reading Hiding (filtering) a specific user from reporting in Cisco ISE
