them is discovered at a time. You must add the access point to the managed list, change
its IP address, and run discovery again to discover the next access point with that IP
address.
• Enable DHCP option 43 (vendor-specific information) on an external DHCP server.
Specifying an internal DHCP server on the wireless controller automatically enables
DHCP option 43 with the IP address of the wireless controller.
How you must configure DHCP option 43 depends on the type of external DHCP server:
- Layer 3 switch as a DHCP server. If you use a Layer 3 switch as a DHCP server,
specify the wireless controller's IP address in hexadecimal format to allow the access
points to receive the wireless controller's IP address and to allow the DHCP server to
assign IP addresses to the access points. The vendor-specific octets 02:04: must
precede the hexadecimal address.
To compose the address, start with 02:04: and then add each of the four address
octets in hexadecimal format, separated by colons. For example:
192.168.33.27 in decimal format equals c0:a8:21:1b in hexadecimal format. After
you add the vendor-specific octets, the complete address is 02:04:c0:a8:21:1b.
In a configuration with stacked wireless controllers, use the octets that are shown in
the following table.
Table 11. Vendor-specific Octets
Number of Controllers
1 wireless controller
2 wireless controllers
3 wireless controllers
In a stacked configuration, to compose the address, start with the corresponding
vendor-specific octet for the number of wireless controllers in the stack. Then add
each of the four address octets in hexadecimal format, separated by colons. For
example:
192.168.33.27 in decimal format equals c0:a8:21:1b in hexadecimal format. After
you add the vendor-specific octet for a stack with three wireless controllers, the
complete address is 02:0c:c0:a8:21:1b.
- Linux-based or Windows-based DHCP server. If you use a Linux-based or
Windows-based DHCP server, configure the IP address in decimal format and
NETGEAR_WNC_AP as the vendor class identifier.
