This document discusses Cisco's Catalyst 9800 Wireless Controller. It introduces the Catalyst 9800 series, which includes the C9800-40 and C9800-80 appliances. The C9800-80 can support up to 6,000 access points and 64,000 clients, while the C9800-40 can support up to 2,000 access points and 32,000 clients. The document also discusses the Cisco Catalyst 9800 Wireless Controller for Cloud and for Switch, which embed the wireless capabilities on switches. It highlights features like seamless software updates, high availability, and support for technologies like SD-Access, ETA, and wireless assurance.

 N+1 rolling AP upgrades help ensure
seamless client connectivity
 Radio Resource Management (RRM)
automates group creation

Software maintenance and AP updates
 Seamless software updates for
wireless controllers and APs
 AP device pack and flexible per-site
updates contain impact area
Unplanned events
Device and network interruptions
 Stateful switchover with an active
standby
 N+1 redundancy for always-on
network, services, and clients
Always on in planned and unplanned scenarios
Impact contained within release
Fixes for defects and security issues without
need to requalify a new release
Faster resolution to critical issues
Provide fixes for critical issues found in
network devices that are time-sensitive

8. Unplanned Events
Always on Network
APs continue to stay
associated
Always on Services
Uninterrupted voice, video and
data services
Always on Clients
Users and end-points continue
to stay connected
How it Works
 Upstream device and network
interruptions trigger a switchover to
maintain end-point connectivity
 Hot standby controller takes over
in case of failure of an active
controller
 Seamless connectivity with
Stateful Switchover (SSO) for end-
points

9. Seamless software update infrastructure
How it Works
 Install controller specific updates
(patches) without client downtime
to fix issues seamlessly
 Service updates for specific
Access Point models without
impacting other models
 New Access Points can join the
controller with an AP device pack
without impacting other APs
