6.2.4.2. Event Counters
This tab allows you to read the events occurring at the link level, such as the number of received errors, framing errors, etc. for each port. You can use the Clear PX counter button at the end of each event counter list to reset these counters. Also, please note that:
- All the information is read-only.
- The per-lane related counters correspond to the logical lanes.
- Use the Refresh Event Counter button to read the event counters' registers.
