Explanation
In the Cisco Hybrid Message Service deployment, the Cisco Tomcat certificate is used to secure AXL (Administrative XML Layer) communication between the Cisco Instant Messaging and Presence (IM&P) server and the Expressway-C server. AXL is required for the Hybrid Message Connector to communicate with the IM&P Publisher to synchronize user data and enable instant messaging functionality between Jabber (on-premises) and Webex (cloud) users. The Cisco Tomcat certificate secures HTTPS communication, including AXL connections. The certificate ensures the Expressway-C can authenticate the IM&P server and establish a trusted, encrypted connection. AXL operates over HTTPS, and the Tomcat service on the IM&P server handles the HTTP/HTTPS interface, making the Cisco Tomcat certificate integral for this communication.
