I must be missing something simple and just am not seeing what I am doing wrong being a newbie to the Aruba system and centralized management with Airwave..
I have 3 sites, Site A, Site B, and Site C. The sites all have their own Windows domain controller which also functions as the DHCP server for those sites. The sites are all connected via site-to-site VPNs.
Site A has The Airwave, ClearPass, and a bunch of APs, all controlled by one Instant Virtual Controller.
Site B and Site C just have APs, all controller by their own Virtual Controller since they are on their own VLAN. The Airwave is on the same VLAN as the DHCP server in Site A. All authentication (RADIUS and LDAP) and DHCP scopes for internal users (VLAN 40 and DHCP 172.16.40.x) and Guest (VLAN 100 and DHCP 172.16.100.x) work fine.
At the remote sites I have the RADIUS authentication working, talking to the Windows DCs at each site. So that is great. I cannot get DHCP to work at each site, where it should be using each sites local DHCP server. DHCP just fails and I am not sure why. The DC is the DHCP server, so I know the server is reachable. I just do not see the DHCP requests reaching the DHCP server.
In Airwave I go to the Instant Config and open the VC. For Site A I just have the correct VLAN entered in the VLAN section for the SSID. At Site B and Site C that did not work so under the DHCP Server I have created Centralized DHCP scopes and have tried to use L2 and L3, but neither are working. It does not seem like I would want to do any of the others.
Am I seeing things correctly and is this the way to do it? Hopefully I am reading the docs correctly, but not certain. It seemed to make sense until the point it did not work.
Thanks for any pointers
