You have a single Cisco 5508 WLC with a management IP address of 172.16.24.5/24. You need to register 50 new Cisco AIR-CAP3702I-E-K9. Access Points to the WLC using DHCP option 43. The access points are connected to a switch in VLAN 37, which uses the 172.16.37.0/24 subnet. You have configured the DHCP scope on the switch like this:
Network 172.16.37.0 255.255.255.0
Default Router 172.16.37.1
Option 43 Aseii 172.16.24.5
The access points are failing to join the wireless LAN controller. Which command fixes the issue?
A. Option 43 Hex F108.CA10.1805
B. Option 43 Hex F104.AC10.1705
C. Option 43 Hex F112.CA10.1805
D. Option 43 Hex F104.AC10.1805
Also, For the first hexadecimal group F104 = 1 WLC, F108 = 2 WLC…
D is correct because…
WLC IP = 172.16.24.5
HEX:
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
Converting IP to Hex…
172 = 1010.1100 = AC (1010 = A and 1100 = C)
16 = 0001.0000 = 10 (0001 = 1 and 0000 = 0)
24 = 0001.1000 = 18 (0001 = 1 and 0000 = 0)
5 = 0000.0101 = 05 (0000 = 0 and 0101 = 5)
F104 + AC101805 = F104.AC10.1805
Its correct. https://shimi.net/services/opt43/
