If I have all my users going through Dynamic Interfaces (ie. not Mgmt i/f) and these users are the only IP devices using DHCP (APs have Static IP addresses configured) then is the Mgmt i/f DHCP server IP address which the WLC inital setup dialog asks for, irrelevant? ie. never used & since I must answer this question in the dialog, can I put in any old IP address?
In theory the mgt dhcp interface is useless. However, in the event of a dhcp server failure on one of your dynamic interfaces, the controller will attempt to revert to the mgt interface for dhcp to assign addresses to any newly discovered APs. Make sense?
Well hopefully you have designed your network to have primary and secondary dhcp. If you are advertising a secondary scope on the vlan that your AP resides, then enabling option 43 will allow the APs to associate to the controller. The management interface doesn't dictate what IP the AP gets. The AP will get that address from the scope it sees advertised. Look at the documents attached.
