Verify Current Cisco IOS Versionīefore starting any upgrades, you need to establish your baseline. For the purpose of demonstration, I wanted to do it the long way, which subsequently has a shorter downtime while the stack reloads. When the master comes up it will see a version mismatch and begin updating and reloading the members. To be completely honest, the additional flash steps below will be a little redundant since updating the master should update all member switches as well. The steps for a single switch are very similar except you’ll only be working with one flash directory and it will most likely be named flash or bootflash instead of flash1, flash2, etc… In this tutorial I’m going to lists the steps for upgrading a stack of 2960-X switches. Plus, let’s be honest, IOS doesn’t change THAT much across devices and deployments and we both know you’re a smart cookie! Hopefully the steps below are close enough that you can extrapolate them to your specific type of hardware. How to Upgrade Cisco IOS Switches and Routersīefore we get to the steps I want to point out that there will be some variation in update steps between single switches and stack switches as well as between switches and routers. This will also make it easier for you to come up with more secure templates since you’ll just have one standard template to run through tools like Nipper to ensure you’re following best practices. You won’t have to keep a separate template for every flavor of IOS you have deployed across the same devices. Keeping everything up to date also aids in keeping your environment standardized. New updates not only fix security holes and bugs but they often enable new features (and deprecate others). but that tells me this person is new to linux in general, or has been Ubuntized beyond Recognition or known as UBR/ubr and knows nothing else and that ubuntu is indeed linux and there is no other distro.Just as patching Windows is regular event so should be updating your Cisco networking equipment.
