Many times I’ll teach an ISE class and folks will ask me how to ensure the switch is configured properly. There are a number of user guides and deployment guides, and blog posts, and videos that show how to configure the switch, and they are no all alike. So how do you reall know if the switch has everything you need for an ISE deployment? Let’s use ISE to tell us!
Using Diagnostic Tools In ISE
It’s fairly easy to test with use assuming that you already have remote access enabled on the switch. Follow these steps:
- First, navigate to Operations>Diagnostics>Troubleshoot.
- Next, select Evaluate Configuration Validator under the General Tools heading.
- Next, enter the IP address of the switch.
- Finally, click Run.
ISE will now connect to your network device. There’s still a bit more work to be done here though. You’ll be prompted to enter device credentials and select the interfaces you want to validate. Once you provide this information to ISE you will get a summary of the troubleshooting results with teh option to click a button labeled Show Results Summary.
Once you click the button you’ll be presented with a summary of what was found.
Expanding a section shows the specific commands found to be missing. While this is a pretty decent tool for validating the configuration just know that not all of the commands are 100% nessecary.
There’s isnt much to say here to wrap this one up. The tool does what it says it does: validates the configuration. By applying the configuration it shows you at least you know you have what you need, and perhaps a bit extra which isnt exactly what one desires. Still, it gets the job done.
