Which port is used for secure HA communication (HA Secure)?

• A. 3008
• B. 3011
• C. 22
• D. 3010

Answer: (A)

In a high-availability setup, the devices need a dedicated, encrypted channel to exchange state, health, and synchronization data without mixing with admin or regular data traffic. The port used for this secure HA channel is 3008, by default, which is specifically reserved for the HA Secure communication. This separation ensures that failover-related information remains confidential and tamper-proof, distinct from management (like SSH on port 22) or other services. The other ports listed are not used for the HA Secure channel, so they don’t provide the same protected path for inter-node communication.
