The new software version here will be 03.06.06E. You can see from the output of the 3650 that the current software version is 03.06.05b.e and it is running in Install Mode.ĭownload your image from Cisco. I would suggest operating in Install mode as this is the default, and provides you with a modular system, you can switch them if you choose. It consumes more memory than Install mode because packages are extracted from the bundle and copied to RAM. Cisco recommends not altering any of the files.īundle mode uses monolithic Cisco IOS images to boot the switch. pkg files found in the flash drive that provide a specific function to the OS. Install mode uses a package-provisioning file named nf, which is in charge of booting the switch. The Cisco Catalyst 3650, 3850, and 9K series switches have two modes of operation, Install Mode and Bundle Mode. Now that you have some understanding of the differences between IOS and IOS-XE you need to understand that there is two modes of operation. Individual sub packages create IOS-XE that can be upgraded individually.Multiprocessing allows for workloads to be shared across multiple CPUs.A single process could crash the entire system.Monolithic – The OS and its processes run in the same address space on the same hardware.
You can also review upgrade procedure for specific hardware.Īs a quick introduction, here are some differences between IOS and IOS-XE. You can view my other post on how to convert IOS XE from Bundled running mode to Install running mode.Ĭonverting Cisco IOS-XE Software from Bundle Mode to Install Mode So today we will be going through the software upgrade process for a 3650 running in install mode. IOS-XE isn’t new, I prefer it over IOS because of its Linux base and the processing advantages it has. I got my hands on a Cisco Catalyst 3650-48PD-L switch which is the first access level switch that I’ve dealt with that is running IOS-XE.
