Chapter 1: Before you begin

DHCP Option 43 configuration

The WLAN 8100 solution requires configuration of DHCP Option 43 to ensure proper operation
of access points and the solution overall. This configuration should be performed before
attempting any operations that require network connectivity between the controller and access
points.
Configuration is dependent on the type of DHCP server in use in the network environment.
Avaya recommends the use of either a Windows 2003 Server or Linux-based DHCP server.
If a Windows 2003 DHCP server is in use, perform the following actions:
1. Open the DHCP Server Manager.
2. Select DHCP > <your-DHCP-server> > Scope > Scope Option > Option 043.
3. Configure Sub-Option 8 as AVAYA AP with hexadecimal values for domain
4. Click OK.
If a Linux DHCP server is in use, perform the following actions:
1. Edit dhcpd.conf (/root/dhcp.conf).
2. Configure Sub-Option 8 as AVAYA AP with hexadecimal values for domain
3. Restart dhcpd.
For example, a Linux entry for Option 43 with controller addresses 192.168.11.2 and
192.168.11.3 and using port 61000 would break down as follows:
option vendor-encapsulated-options 08:08:41:56:41:59:41:20:41:50 =
"AVAYA AP"
:01:04:c0:a8:0b:02 = "192.168.11.2"
:01:04:c0:a8:0b:03 = "192.168.11.3"
:03:02:EE:48 = "61000"
The total Option 43 entry would be:
08:08:41:56:41:59:41:20:41:50:01:04:c0:a8:0b:02:01:04:c0:a8:0b:
03:03:02:EE:48
