Cisco Connected Mobile Experiences Cloud

Cisco Connected Mobile Experiences (CMX) communicates with the Cisco wireless controller using the Network Mobility Services Protocol (NMSP), which runs over a connection-oriented (TLS) transport. This transport provides a secure 2-way connectivity and is convenient when both the controller and CMX are on-premise and there is direct IP connectivity between them.

Cisco CMX Cloud is a cloud-delivered version of the on-premise CMX. To access Cisco CMX Cloud services, HTTPS is used as a transport protocol.

Configuring Cisco CMX Cloud

Follow the procedure given below to configure CMX Cloud:

Before you begin

  • Configure DNS—To resolve fully qualified domain names used by NMSP cloud-services, configure a DNS using the ip name-server server_address configuration command as shown in Step 2.

  • Import 3rd party root CAs—The controller verifies the peer and the host based on the certificate that is sent by the CMX when a connection is established. However, root CAs are not preinstalled on the controller. You have to import a set of root CAs trusted by Cisco to the trustpool of the crypto PKI by using the crypto pki trustpool import url <url> configuration command as shown in Step 3.

  • A successful registration to Cisco Spaces is required to enable server url and server token parameters configuration which is needed to complete this setup.

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ip name-server namesvr-ip-addr

Example:

Device(config)#ip name-server 10.10.10.205

Configures the DNS on the controller to resolve the FQDN names used by the NMSP cloud-services.

Step 3

crypto pki trustpool import url url

Example:

Device(config)#crypto pki trustpool import url http://www.cisco.com/security/pki/trs/ios.p7b

Imports the 3rd party root CA. The controller verifies the peer using the imported certificate.

Step 4

[no] nmsp cloud-services server url url

Example:

Device(config)# nmsp cloud-services server url https://cisco.com

Configures the URL used for cloud services. Use the no form of the command to delete the server url from the configuration.

Step 5

[no] nmsp cloud-services server token token

Example:

Device(config)# nmsp cloud-services server token test

Configures the authentication token for the NMSP cloud service. Use the no form of the command to delete the server token from the configuration.

Step 6

[no] nmsp cloud-services http-proxy proxy-server port

Example:

Device(config)# nmsp cloud-services http-proxy 10.0.0.1 10

(Optional) Configures HTTP proxy details for the NMSP cloud service. Use the no form of the command to disable the use of a HTTP proxy.

Step 7

[no] nmsp cloud-services enable

Example:

Device(config)# nmsp cloud-services enable

Enables NMSP cloud services. Use the no form of the command to disable the feature.

Verifying Cisco CMX Cloud Configuration

Use the following commands to verify the CMX Cloud configuration.

To view the status of active NMSP connections, use the following command:
