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 “-” will be
displayed.
♦ 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 64 th byte (octet) in the frame.
