Cisco Catalyst 9130AX Series Access Points
ip dhcp pool <pool name>
network <IP Network> <Netmask>
default-router <Default router>
dns-server <DNS Server>
Where:
<pool name> is the name of the DHCP pool, such as AP9130AX
<IP Network> is the network IP address where the controller resides, such as 10.0.15.1
<Netmask> is the subnet mask, such as 255.255.255.0
<Default router> is the IP address of the default router, such as 10.0.0.1
<DNS Server> is the IP address of the DNS server, such as 10.0.10.2
Step 3
Add the option 43 line using the following syntax:
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
W hat 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.
W hat are Self Identifying Antennas?
Self-Identifying Antennas with 8-port DART connectors are a new set of external, dual-band antennas that are supported
with specific 802.11ax APs like the 9130AXE model. These new antennas are based on currently existing Cisco
antennas.
Before the introduction of Self Identifying Antennas, the wireless controller and network management system had to be
manually provisioned with antenna details like the type of antenna connected to the AP and the antenna's gain values.
With these new antennas and adapters (AIR-CAB002-D8-R= and AIR-CAB003-D8-N=) to support legacy antennas, the
AP can automatically detect and identify the external antenna and configure these values without user intervention.
W hat is Flexible Radio Assignment?
The Flexible Radio Assignment (FRA) feature automatically detects when a high number of devices are connected to a
network and changes the dual radios in the access point from 2.4 GHz/5 GHz to 5 GHz/5 GHz to serve more clients. The
access point performs this function while still monitoring the network for security threats and RF Interference that may
affect performance. Flexible Radio Assignment improves mobile user experience for high-density networks.
