Cisco Catalyst 9120AX Series Access Points
For example, suppose that there are two controllers with management interface IP addresses, 10.126.126.2 and
10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and
0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the
DHCP scope is option 43 hex f1080a7e7e020a7f7f02.
