Hi friend,
You can achieve this by using NAS ID in radius server profile.
1. Create two separate RADSIUS server profiles with different NAS IDs ( EX : LOC1 and LOC2)
2. Create two separate AAA profiles and map these two RADIUS servers
3. Create two AP-Groups and map these AAA profiles.
4. Provision APs accordingly.
Now Authenticator will send different NAS ids based on the AP location.
Hope you got some solution, please feel free for any further help on this.
