Since a WLC manages multiple APs, the redundancy of the WLC becomes critical for ensuring Wi-Fi service availability. The WLC redundancy is provided in the ways as follows:
- N+1 WLC redundancy: In this deployment, a separate WLC is deployed, and all APs are mapped to the WLCs in such a manner that the outage of one AP still ensures that the APs have a redundant configured as a secondary or a tertiary AP. Note that in this deployment, all WLCs are actively managing some APs at a given point in time.
- N+1 HA WLC redundancy: This type of deployment ensures a single WLC that is configured as a backup WLC for all APs on the network, with the remaining N WLCs working as the primary WLC for the active APs. Note that the configuration ...
