Auto-Anchor mobility, also known as Foreign Mapping, allows you to configure users that are on different foreign controllers from different physical location to obtain IP addresses from a subnet or group of subnets based on their physical location.
Configuring Foreign Controller MAC Mapping (GUI)
Choose the WLANs tab.
The WLANs page appears listing the available WLANs.
Click the Blue drop down arrow for the desired WLAN and choose Foreign-Maps.
The foreign mappings page appears. This page also lists the MAC addresses of the foreign controllers that are in the mobility group and interfaces/interface groups.
Choose the desired foreign controller MAC and the interface or interface group to which it must be mapped and click on Add Mapping.
Configuring Foreign Controller MAC Mapping (CLI)
To add foreign controller mapping, enter this command:
