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.

Explanation
https://www.cisco.com/c/en/us/td/docs/wireless/mse/106/cmx_config/b_cg_cmx106/managing_cisco_cmx_syste Pre-requisites for HA Both the primary and the secondary server should be of the same size and the same type (VM or physical appliance).
Both the primary and the secondary server should have the same Cisco CMX version.
Both the primary and the secondary server should be connected on the same subnet.
Both the primary and the secondary server should be connected on the same subnet if Layer 2 HA is required.
Both the primary and the secondary server should be IP connected with delay of less then 250ms if Layer 3 HA is used.
From Cisco CMX release 10.6.2, NTP server settings must be configured on both Primary and Secondary server instance before HA pairing starts. We recommend that you use the same NTP server on both Primary and Secondary. As a Cisco CMX admin you can also use a dedicated NTP for Primary and Secondary.

Local EAP is an authentication method that allows users and wireless clients to be authenticated locally on the controller. It is designed for use in remote offices that want to maintain connectivity to wireless clients when the backend system becomes disrupted or the external authentication server goes down. When you enable local EAP, the controller serves as the authentication server and the local user database, so it removes dependence on an external authentication server.
