Interconnect Channels and Ports

There are many interconnect ports in the PMC, PS, and CPM. The ports are characterized as follows:

• Host: Host interfaces source the transaction and are connected to an iPort
• ProgIF: Register programming interfaces often have an ePort
• Config: Configuration interfaces have an ePort, but never an iPort
• Switch: Types of interface channels attached to port modules:
  • Interface includes an ePort and iPort module
  • ePort module to another switch without an iPort module
  • Neither interface has a port because the channel is a path within switches in the same domain or has other protection

The PMC, PS, and CPM interface channels are listed in the following table.
