Cisco Catalyst 9136I Series Access Points
option 43 hex <hex string>
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.

FAQs
What is 802.11ax?
The IEEE 802.11ax standard, also known as the High-Efficiency Wireless (HEW) or Wi-Fi 6, builds off of the 802.11ac
and delivers a better experience in typical environments, and a more predictable performance for advanced applications
such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and
Internet-of-Things (IoT). 802.11ax is designed to use both 2.4Ghz and the 5GHz bands, unlike prior standards.
What is Wi-Fi 6E?
The IEEE 802.11ax standard, also known as High-Efficiency Wireless (HEW) or Wi-Fi 6, builds on 802.11ac. It delivers a
better experience in typical environments with more predictable performance for advanced applications such as 4K or
8K video, high-density, high-definition collaboration apps, all-wireless offices, and IoT. Wi-Fi 6E is Wi-Fi 6, "Extended"
into the 6 GHz band.
What is Cisco Multigigabit Ethernet?
Cisco Multigigabit Ethernet (mGig) is a unique Cisco innovation also available in the Cisco Catalyst 9136I series access
point. With the increasing popularity of 802.11ax and new wireless applications, wireless devices now require more
network bandwidth. Hence, there is a need for a technology that supports speeds higher than 1 Gbps on all cabling
infrastructure. Cisco Multigigabit technology allows you to achieve bandwidth speeds from 1 to 10 Gbps over traditional
Cat 5e cabling or newer. The C9136I AP supports up to 5 Gbps using mGig.
