High availability with SSO
The 9800-L supports both full access point and client Stateful Switchover (SSO). Client SSO is available for clients who have passed the authentication and DHCP phases and are now passing traffic. Client SSO syncs a client's information to the standby wireless controller when they associate or modify their parameters.
Fully authorized clients in the run state are synced to the standby, eliminating the need for client re-association during switchover. This ensures flawless failover for both the APs and clients.
This procedure yields zero client service downtime and zero SSID outages. The Cisco Catalyst 9800-L Wireless Controller now supports AP and client SSO, reducing downtime caused by failures such as box failover, network failover, or power outages at the primary site.
