By default, Encryption Management Server uses network Interface 1 for clustering and replication. Note that Symantec Encryption Management Server (PGP Server) refers to the first network interface - normally eth0 - as Interface 1.
If Encryption Management Server has more than one network interface, a different network interface can be used for clustering and replication. However, before making this change, please consider the following:
Symantec Encryption Management Server 10.5 and above.
For these types of issues and for more technical clustering, please reach out to Symantec Encryption Support for further assistance.
