Provisioning Access Points 9
Chapter 2
Discovery of the serverip and master variables is necessary when the DHCP
response does not include the Vendor Specific option. The AP attempts to
discover an Alcatel Master switch by sending multicast packets and
broadcast packets on its subnet. To use the ADP discovery method, the ADP
discovery mechanism needs to be enabled on the Alcatel Master Switch
(using the adp discovery enable command).
If multicast routing is enabled in the IP network between the AP and the
Master switch (which can be any one or more Alcatel Wireless LAN switches
in the network), the IGMP-Join option should be enabled on the Alcatel
Wireless LAN switch (using the adp igmp-join enable command). If multicast
routing is not enabled on the network, the Alcatel Wireless LAN switches
need to be on the same broadcast domain as the AP or an “IP Helper” must be
configured to direct the broadcast ADP packets to the Alcatel Wireless LAN
switch.
Once these discovery prerequisites are met, the switch will respond to APs
with the IP address of the Master Alcatel switch. The APs can then obtain
their image and configuration.
To enable ADP on an Alcatel Wireless LAN switch, enter:
(A6000) (config) #adp discovery enable
To enable IGMP-Join on an ADP multicast group on an Alcatel Wireless LAN
switch, enter:
(A6000) (config) #adp igmp-join enable

OTE—If you have location-specific configurations for your Access Points, you will need to apply this
configuration information using AP Reprovisioning. Refer to the User Guide for details on AP Repro-
visioning and see the feature description below.
AP Reprovisioning
AP Reprovisioning is the process by which APs are assigned, for example,
location codes. Location codes are important for recalibration and
triangulation. For details on AP Reprovisioning, see the User Guide.
