: Features are separated into distinct packages that use memory more effectively. : Certain modern capabilities, like auto-upgrade , are only supported in Install mode. Conversion Process (One-Step Method)
The command will take a few minutes to complete.
Think of a .bin file like a zipped folder. In Bundle Mode, every time the switch reboots, it has to decompress that entire .bin archive directly into the device's RAM. In Install Mode, you extract those individual .pkg files directly onto the local flash storage beforehand.
If the output shows , you need to convert it. Take note of your current boot variable as well: Switch# show boot Use code with caution. Step 2: Clean Up Flash Storage
While the push is toward Install Mode, there may be rare scenarios where you need the opposite: consolidating .pkg files back into a single .bin image. The official command to do this is request platform software package consolidate . However, it's crucial to note that this command is ; it is primarily found in the IOS XE code for SD-WAN edge routers, and may not work on standard ISR or Catalyst switches.
Network engineers frequently debate the best way to boot Cisco Catalyst switches. When you download software from Cisco, it usually arrives as a monolithic .bin file. While running your switch in this standard format is easy, converting it to a modular .pkg (packages) format offers massive operational advantages.
When a switch boots in , the core operating system runs directly out of a single, compressed .bin file. In contrast, Install mode unpacks this single file into separate, modular component packages ( .pkg files) and references them using a base provisioning file ( .base or .conf ).
When upgrading Cisco Catalyst switches, specifically the 3850, 9000 series, and newer models, you will encounter two primary operating modes: Bundle Mode and Install Mode. While Bundle Mode uses a single .bin file, converting that file into .pkg files (Install Mode) is widely considered the superior method for managing enterprise networks.
