Cisco Catalyst IW9167I - Compliance Statement for Canada; European Community, Switzerland, Norway, Iceland, and Liechtenstein

The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
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.
