The Cisco Neighbor Discovery
Packet (NDP) is the fundamental tool for RRM and other wireless applications
that provides information about the neighbor radio information. You can
configure the Cisco WLC to encrypt neighbor discovery packets.
This feature enables you to
be compliant with the PCI specifications.
An RF group can only be
formed between Cisco WLCs that have the same encryption mechanism. That is, an
access point associated to a Cisco WLC that is encrypted can not be neighbors
with an access point associated to a Cisco WLC that is not encrypted. The two
Cisco WLCs and their access points will not recognize each other as neighbors
and cannot form an RF group. It is possible to assign two Cisco WLCs in a
static RF group configuration that has mismatched encryption settings. In this
case, the two Cisco WLCs do not function as a single RF group because the
access points belonging to the mismatched Cisco WLCs do not recognize one
another as neighbors in the group.
Configuring RRM NDP (CLI)
To configure RRM NDP using the Cisco WLC CLI, enter this command:
