Need for Primary Controller on AP config

[johnlloyd_13]

hi all,

i'm configuring our WLC 2504. just want to know if we still need to specify the primary controller under high availability if there's only 1 WLC?

refer to link:

High Availability in Release 7.3 and 7.4

The new architecture for HA is for box-to-box redundancy. In other words, 1:1 where one WLC will be in an Active state and the second WLC will be in a Hot Standby state continuously monitoring the health of the Active WLC via a Redundant Port. Both the WLCs will share the same set of configurations including the IP address of the Management interface. The WLC in the Standby state does not need to be configured independently as the entire configuration (Bulk Configuration while boot up and Incremental Configuration in runtime) will be synced from the Active WLC to the Standby WLC via a Redundant Port. The AP's CAPWAP State (only APs which are in a run state) is also synced, and a mirror copy of the AP database is maintained on the Standby WLC. The APs do not go into the Discovery state when the Active WLC fails and the Standby WLC takes over the network's Active WLC.

so you can't configure HA with single WLC.

You don't have to, but is good practice to define it. As long as the AP joins the WLC, it will know of that WLC. Scott

No is not necessary.
