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 OmniAccess 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 OmniAccess 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 OmniAccess Wireless LAN
switches in the network), the IGMP-Join option should be enabled on the
OmniAccess Wireless LAN switch (using the adp igmp-join enable command).
If multicast routing is not enabled on the network, the OmniAccess 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
OmniAccess Wireless LAN switch.
Once these discovery prerequisites are met, the switch will respond to APs
with the IP address of the Master OmniAccess switch. The APs can then
obtain their image and configuration.
To enable ADP on an OmniAccess Wireless LAN switch, enter:
(6000) (config) #adp discovery enable
To enable IGMP-Join on an ADP multicast group on an OmniAccess Wireless
LAN switch, enter:
(6000) (config) #adp igmp-join enable

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 AOS-W User Guide.
