Important Notes for Controllers and Non-Mesh Access Points
RLDP Limitations in This Release
Rogue Location Discovery Protocol (RLDP) is a controller feature that detects the presence of rogue
access points that are connected to your wired network. In this software release, RLDP operates with
these limitations:
access points that are connected to your wired network. In this software release, RLDP operates with
these limitations:
•
RLDP detects rogue access points that are configured for open authentication.
•
RLDP detects rogue access points that use a broadcast BSSID (that is, the access point broadcasts
its SSID in beacons).
its SSID in beacons).
•
RLDP detects only rogue access points that are on the same network. In other words, if an access
list in the network prevents the sending of RLDP traffic from the rogue access point to the controller,
RLDP does not work.

RLDP does not work.
•
RLDP does not work on 5-GHz dynamic frequency selection (DFS) channels.
•
If the automatic RLDP attempt does not detect the rogue (due to a noisy RF environment, for
example), the controller does not retry. However, you can initiate RLDP manually on a rogue at any
time.

Also, in controller software release 6.0, the rogue containment packet transmission times have changed
as follows:
as follows:
•
For monitor mode, rogue containment deauthentication packets are still sent at 100-msec intervals.
•
For non-monitor mode, deauthentication packets are sent at 500 msec (minimum). In previous
releases, they are sent at 100-msec intervals.

Internal DHCP Server
When clients use the controller’s internal DHCP server, IP addresses are not preserved across reboots.
As a result, multiple clients can be assigned the same IP address. To resolve any IP address conflicts,
clients must release their existing IP address and request a new one.
