  Cisco Adaptive wIPS Introduction
wIPS Communication Protocols
To provide communication between each system component, a number of protocols are utilized:
CAPWAP (Control and Provisioning of Wireless Access Points) – This protocol is utilized for 
communication between Access Points and controllers. It provides a bi-directional tunnel in which 
alarm information is shuttled to the controller and configuration information is pushed to the Access 
Point. CAPWAP control messages are DTLS encrypted and CAPWAP data has the option to be 
DTLS encrypted
NMSP (Network Mobility Services Protocol) – The protocol used for communication between 
Wireless LAN Controllers and the Mobility Services Engine. In the case of a wIPS Deployment, this 
protocol provides a pathway for alarm information to be aggregated from controllers to the MSE and 
for wIPS configuration information to be pushed to the controller. This protocol is encrypted.
Controller TCP Port: 16113
SOAP/XML (Simple Object Access Protocol) - The method of communication between the MSE 
and PI. This protocol is used to distribute configuration parameters to the wIPS service running on 
the MSE.
oMSE TCP Port: 443
SNMP (Simple Network Management Protocol) – This protocol is used to forward wIPS alarm 
information from the Mobility Services Engine to the Prime Infrastructure. It is also utilized to 
communicate rogue access point information from the Wireless LAN Controller to the Prime 
Infrastructure.
wIPS Configuration and Profile Management
Configuration of wIPS Profiles follows a chained hierarchy starting with PI, which is used for profile 
viewing and modification. The actual profiles are stored within the wIPS service running on the MSE. 
From the wIPS Service on the MSE, profiles are propagated to specific controllers, which in turn 
communicate this profile transparently to wIPS Mode Access Points associated to that perspective 
controller. When a configuration change to a wIPS profile is made at PI and applied to a set of Mobility 
Services Engine(s) and Controller(s), the following steps occur to put the change in place:
1.
The configuration profile is modified on PI and versioning information is updated.
2.
An XML-based profile is pushed to the wIPS Engine running on the MSE. This update occurs 
via the SOAP/XML protocol.
3.
The wIPS Engine on the MSE will update each controller associated with that profile by pushing 
out the configuration profile via NMSP.
