WLC 850 with HA & Mobility Anchor

[Craig Le-Butt]

Hi

We're looking at implamenting SSO with 2 * 8500 WLC, my question is how will mobility anchors behave with SSO, if HA became active, the mac address wont match the one set in the mobility anchor on the other agencys wlc, or does the HA spoof the MAC?

Cheers

Enabling SSO will reboot the WLCs in order to negotiate the HA role as per the configuration performed. Once the role is determined, configuration is synced from the Active WLC to the Standby WLC via the Redundant Port. Initially WLC configured, as Secondary will report XML mismatch and will download the configuration from Active and reboot again. During the next reboot after role determination, it will validate the configuration again, report no XML mismatch, and will process further in order to establish itself as the Standby WLC.

The mac address will match.... the HA will take over all the settings from the primary.  Don't worry about it to be honest.  I have multiple deployments with AP SSO and multiple guest anchors with no issues.
