The Management Connector is included in the Expressway-C base. You use it to register an Expressway to the cloud and link the Expressway interface with Cisco Webex Control Hub. The Management Connector plays an important role as the coordinator of all connectors running on the Expressway server or cluster: It provides you with a single point of control for connector activities. The Management Connector enables cloud-based management of the on-premises connectors, handles initial registration with the cloud, manages the connector software lifecycle, and provides status and alarms.
For an HTTPS connection to be established between the Management Connector and the cloud, you must update the trust list on the Expressway-C connector host with certificates that were signed by certificate authorities in use by the Cisco Webex cloud. You can allow the Cisco Webex cloud to upload CA certificates to the Expressway-C trust store. Or, in the case where security policies prevent the Cisco Webex cloud from uploading trusted certificate authority certificates on Expressway-C, you may upload them manually.
