Switch Ports Model SW Version SW Image Modeġ 32 WS-C3850-24P 03.03.00SE cat3k_caa-universalk9 INSTALL (CAT3K_CAA-UNIVERSALK9-M), Version 03.03.00SE RELEASE SOFTWARE (fc1) In order to verify the mode, enter the show version command: 3850-stack# show versionĬisco IOS Software, IOS-XE Software, Catalyst 元 Switch Software The BUNDLE mode consumes more memory than the INSTALL mode because the packages are extracted from the Bundle and copied to the RAM.
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. Cisco recommends that you do not alter these files unless directed by a Cisco Technical Assistance Center (TAC) engineer. The INSTALL mode uses a package-provisioning file named nf in order to boot the switch. As a result of this software defect, bundle mode is recommended for upgrades involving the effected software versions Install Mode This issue is resolved in 3.6.4 or 3.7.3 or later software therefore the issue is not seen when upgrading to these software versions. Note: Software defect CSCuw82216may result in switch inoperability due to flash memory corruption when upgrading from a pre-3.6.3 or pre-3.7.2 software release to 3.6.3/3.7.2 in install mode. This document provides a brief overview of each mode for reference. Review the configuration guide for more details.Ĭisco 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. There are minor differences between the two modes. When you deploy the Cisco Catalyst 3850 Series Switch, you have two modes of operation to choose from: INSTALL and BUNDLE. Also, Cisco does not offer a free TFTP/FTP solution, so you must install and configure the TFTP/FTP before you begin. Note: In order to download Cisco IOS-XE images from the Cisco website, you must have a valid Cisco Connection Online (CCO) account with entitled credentials. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The examples in this document use a stacked solution however, the same commands can be run on a standalone switch. The information in this document is based on the Cisco Catalyst 3850 Series Switch that runs Cisco IOS-XE Versions 03.03.00 and later. Prerequisites RequirementsĬisco recommends that you have knowledge of these topics: The upgrade process is simple, but it can seem difficult if you do not have experience with Cisco IOS ® XE software upgrades. This document describes how to streamline the upgrade process for Cisco Catalyst 3850 Series Switches and offers disaster recovery techniques in the case of a software or boot failure.
