My Network Lab: Cisco 3850 IOS Bundle to Install Mode Conversion

Here's a good Cisco link comparing the Install versus Bundle Mode on a Catalyst 3850 switch (also applies to a 3650 switch).

Install Versus Bundle Mode

When you deploy the Cisco Catalyst 3850 Series Switch, you have two modes of operation to choose from: INSTALL and BUNDLE. There are minor differences between the two modes. Review the configuration guide for more details.

Cisco recommends that the INSTALL mode is used during operation because it allows for a more complete set of features and requires fewer resources upon boot.

Install Mode

This is the default mode for the switch. The INSTALL mode uses a package-provisioning file named packages.conf in order to boot the switch. In addition, there are a number of .pkg files in the flash.

Cisco recommends that you do not alter these files unless directed by a Cisco Technical Assistance Center (TAC) engineer.

Bundle Mode

If you are comfortable with the use of traditional monolithic IOS images in order to boot the switch, then the BUNDLE mode should be familiar. The BUNDLE mode consumes more memory than the INSTALL mode because the packages are extracted from the Bundle and copied to the RAM.

Use the show version command to verify the current boot image and IOS mode, which is in BUNDLE mode.

Extract or expand the BUNDLE image to flash memory using the software expand running to flash: command. Notice the running-packages.conf was created since there's already an existing packages.conf file using the old image (03.02.03).

3850#software expand running to flash:

Preparing expand operation ...

[1]: Expanding the running bundle

[1]: Copying package files

[1]: A different version of provisioning file packages.conf already exists in flash:.

The provisioning file from the expanded bundle will be saved as

flash:running-packages.conf

[1]: Package files copied

[1]: Finished expanding the running bundle

The BUNDLE mode uses the traditional boot command to point the .bin file.
