The Virtual IP is initially bound to the Primary Server (Central Server). If this server becomes unreachable, the Virtual IP is automatically transferred to the Secondary Server (Failover Server). Agents do not need to know which server is active, they communicate with the Virtual IP , ensuring continuous operation without manual reconfiguration. Endpoint Central Console can be accessed using Virtual IP.
When selecting a VIP, follow these guidelines:
In normal scenario, agents communicate with the Virtual IP ,which is assigned to the Primary Server (Central Server). The Virtual IP handles all communication between the agents and the primary server.
If the Primary Server fails, the Virtual IP automatically switches to the Secondary Server (Failover Server). Agents continue to communicate with the Virtual IP ,which now routes traffic to the secondary server. The agents remain unaware of the server switch because they still connect to the same Virtual IP.
Note: The ports mentioned under 'Server' must be enabled at all times irrespective of your license edition. Refer the ports required for specific modules and enable them as per your requirement.
Note: Ports 135,139 and 445 should also be kept open and inbound on both agent and server (and distribution server, if applicable) for pushing agent installation.
