More about this event:
Join us for an Ask Me Anything (AMA) event where you can dive deep into Cisco Catalyst 9000 Switch Upgrades!
What is it?
The Cisco Catalyst 9000 family of switches are Cisco’s lead fixed, modular and compact enterprise access, aggregation and core switching platform. They are built to transform your network to handle a hybrid world where the workplace is anywhere, endpoints could be anything, and applications are hosted all over the place.
The Catalyst 9000 family, including the new Catalyst 9000X models, continue to shape the future with ongoing innovation that helps you reimagine connections, reinforce security, and redefine the experience for your hybrid workforce big and small.
- Install & Bundle Modes: Bundle mode is the traditional method of upgrading a Catalyst Switch. You boot a .bin file that contains everything you need to run the Cisco IOS. As per traditional Cisco IOS, you have a boot statement that points to the .bin file you want to load and that gets loaded at the time of boot. The Install mode is the newer and recommended mode to run. This breaks the .bin file up into smaller .pkg files that must be loaded into memory independently of each other, and allows you to boot faster and utilize memory better. The .bin file that you download from software.cisco.com has all the .pkg files you need inside.
- ISSU Upgrade: In-Service Software Upgrade (ISSU) is a procedure to upgrade a Switch image to a later release while the network continues to forward packets. ISSU helps network administrators avoid a network outage in a critical environment (Ex - Hospital) while performing a software upgrade.
- Auto-Upgrade: Auto-Upgrade allows the Active supervisor to upgrade the Standby supervisor regardless of what image is loaded onto the standby (bundle/install/etc). However, you have to boot the standby into some valid image in order for the process to start.
