Appendix A Network ports and protocols
PS Series groups use a number of TCP and UDP protocols for group management, I/O operations, and
internal communication. If you have switches or routers set to block these protocols, you may need to
unblock them to allow management or I/O operations to work correctly. The required and optional
protocols are listed in the following sections.
A.1 Required ports and protocols
