Why each option
For DHCP Option 43 to function correctly with modern Access Point (AP) models, the information must be formatted using hexadecimal characters.
MD5 is a hashing algorithm and not a character formatting for data transmission in DHCP Option 43.
Base64 is an encoding scheme but is not the required format for DHCP Option 43 with Cisco APs.
ASCII represents characters directly, but DHCP Option 43 for Cisco APs specifically requires hexadecimal encoding for the WLC IP address or other vendor-specific information.
DHCP Option 43 is a vendor-specific option used by Cisco APs to discover Wireless LAN Controllers (WLCs). Current AP models expect the WLC IP addresses or hostname to be provided in a hexadecimal string format within Option 43.
