Alcatel Discovery
Protocol (ADP) - Plug
and Play
Alcatel APs are factory configured with ADP, a
feature that allows plug and play provisioning for APs
connected via Layer 2/3 to a master Alcatel Mobility
Controller on an ADP-enabled network.
ADP equipped APs send out periodic multicast and
broadcast queries to locate a master Alcatel Mobility
Controller. If an Alcatel switch is present in the same
broadcast domain as the APs, it will respond with the
switch/loopback IP address of the master switch.
If the APs and Alcatel switch reside in different
broadcast domains, the APs can discover the Alcatel
master switch using IP multicast (IP multicast must
be enabled in the network for this to function). The
ADP multicast queries are sent to the IP multicast
group address 224.0.82.11.
Alternatively, you can configure a master Alcatel
Mobility Controller address as the IP Helper/relay
address on any Layer-3 switch on the same
broadcast domain as the APs, thus mitigating the
need to enable multicast in the network.
ADP also functions for APs connected directly to
Ethernet ports on a master Alcatel Mobility
Controller. To configure this option see “A l c a t e l
Discovery Protocol (ADP)”.
