    DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type. Cisco Aironet 1000 and 1500 series access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV) format for DHCP Option 43.
