meaning since the last time they were cleared.

• Collision event has not been detected
• Late collision event has not been detected
• Rx error event has not been detected
• Packet has a valid CRC
To view the RMON statistics:

STEP 3 Select the Refresh Rate, the time period that passes before the interface
statistics are refreshed.
