Port Packet Error Statistics
To access the third item on the Traffic Statistics menu, choose Port Packet Error Statistics. The
following table appears:
Select the desired setting in the Ports field: 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21-S1P2, or Slot 2 and the
desired increment setting in the Polling Interval field: 2 sec, 5 sec, 15 sec, 30 sec, 1 min, or Suspend.
Pressing CLEAR COUNTER resets the counters on this screen.
The statistic counters displayed are defined as follows:
♦ Speed If the link is up, the speed and duplex status will be displayed; if the link is down "-" will be
displayed.
♦ CRC Error The number of frames that fail the CRC integrity check.
♦ Oversize Frames The number of good frames with length greater than 1518 bytes and therefore are
greater than the maximum legal length.
♦ Fragments The number of packets less than 64 bytes with either bad framing or an invalid CRC.
These are normally the result of collisions.
♦ Jabber The number of frames with length more than 1518 bytes and with CRC error or misalignment
(bad framing).
♦ Late Collision The number of collisions that occur at or after the 64
♦ Mac Rx Error The number of frames with received MAC Errors.
