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.

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

Seamless SW Updates
Update (patch) controllers without client
downtime. Update specific model APs
with AP Service Pack
Flexible Per-Site Updates
AP Device Pack
Introduce new AP models in your
network without any downtime and
without impacting other APs
