BRKARC-3300 – IOS-XE: Enabling the Digital Network Architecture
Presented by Muhammad A Imam, Sr Manager Technical Marketing Engineering
Brand new session!
The goal of the session is to give an understanding of IOS-XE Denali 16.x.
“How many have downloaded 16.x?” — maybe 10% put up their hands
The upcoming 16.3 (target for this month) will support Cat 3850,3650, ISR, and ASR 1000.
The original operating system on the AGS, back in 1986, was simply called “Operating System”. There are still parts of Operating System in IOS today (scary!!).
IOS-XE (code name BinOS) came around in 2007 on the ASR 1000. In 2010, IOS-XE (code name Nova) was released for the Cat4k. These two editions of XE were similar, but different and were written by different engineering teams.
The vision for IOS-XE Denali is a single code base across Cisco enterprise platforms. Benefits include: similar features, consistent version numbers, consistent release schedule, consistent test and validation of releases, consistent commands (eg “show platform …”).
“We are changing the way we write code” –Muhammad; code is being pulled out of the IOSd blob and written as a subsystem within IOS-XE (over time).
Crimson database:
- New component in Denali
- Maintains state for subsystems
- Holds configuration
