Hi. We have 820 access points (3805i) , and 2 identifi controllers. Controllers and access points are in single vlan (vlan30).. We recently added 20 more ap's of same model,but this time ap's are in different vlan (vlan31), we configured option 43 also and defined controller ip's in dhcp scopes. Now the issue is 20 ap's are getting ip address , we can see them on dhcp server. But they are not showing up in controller....what could be the issue.... 1st controller IP is 172.22.68.251 , with AP registration enabled. 2nd controller IP is 172.22.68.252 with AP registration enabled.
