Port Counters
Port Counters describe the status of signals and interfaces. SLC updates and increments
the port counters as signals change and data flows in and out of the system. These
counters help troubleshoot connections or diagnose problems because they give the user
an overview of the state of various parameters. By setting them to zero and then re-
checking them later, the user can view changes in status.
