Configure DHCP option 43 on Cisco devices for Avaya AP8120

[asimbu]

Hello guys,

How to configure DHCP option 43 in Cisco devices (L3 switches/routers) in order for Wireless AP 8120 to discover wireless controller IP address? I configured the DHCP option on Cisco L3 switch as follow;

cisco(dhcp-config)# option 43 hex 0xC0A8050C

where 0xC0A8050C is 192.168.5.12. Our wireless controller is on VLAN2 while our wireless AP is on VLAN4. I configured the DHCP options and related for VLAN4.

Is this the correct command or I did something wrong here? Our wireless controller unable to discover our AP yet.

Please advice.

Regards,

Alex

Finally found out on how to properly configure Cisco IOS DHCP option in Cisco switches or routers. Below is the Cisco DHCP configuration for Avaya Wireless AP8120:

ip dhcp pool Avaya_WiFi
network 192.168.5.128 255.255.255.192
default-router 192.168.5.129
dns-server 192.168.100.40
option 43 hex 0808.4156.4159.4120.4150.0104.c0a8.05b7

Where,

AVAYA AP = 0808.4156.4159.4120.4150 (Mandatory Prefix)
192.168.5.183 = 0104.c0a8.05b7 (replace this with your assigned IP. Note: Each IP Addresses must include the prefix 0104 + the HEX address of the IP)
