Hi @yogesh1
Not sure if I understood but if this two vlan were extended to the WLC, assuming you are talking about that, then, you can create a interface group, put those two vlans and WLC will allow clients get IP from two vlans.
If you are not talking about a PC then either it uses one or other as it has only one dhcp server option.
