Port Packet Error Statistics
To access the third item on the Traffic Statistics menu, choose Port Packet Error Statistics. The following table appears:
Figure 6-48. Port Packet Error Statistics table
Select the desired device in the Switch field, the desired setting in the Ports field, and the desired increment setting in the Update Interval field: 5 sec, 15 sec, 30 sec, 1 min, or Suspend.
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
♦CRC Error The number of frames that fail the CRC integrity check.
♦Oversize The number of good frames with length greater than 1536 bytes and therefore are greater than the maximum legal length.
♦Bad Fragment 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 1536 bytes and with CRC error or misalignment (bad framing).
♦Late Collision The number of collisions that occur at or after the 64th byte (octet) in the frame.
