Gigabit Ethernet Switch User's Guide Figure 6-55. Port Error Packet Statistics screen The information displayed above includes: ♦ Ports This field always displays either "1 to 4" or "5 to 8" in this 8-port switch version. ♦ Polling Interval Select the desired update increment setting from: 1 sec, 5 sec, 15 sec, 30 sec, 1 min, or Suspend. ♦ CRC Errors 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. ♦ Jabbers 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 64th byte (octet) in the frame. ♦ Mac Rx Errors The number of frames with received MAC Errors. ♦ Dropped Frames Counts received packets which are dropped due to any of the following reasons: lack of available receive buffers, port-disable, link-test-fail, spanning tree, or empty distribution list. ♦ Total errors The sum of the CRC Errors, Oversize Frames, Fragments, Jabbers, Late Collision, Mac Rx Errors, and Dropped Frames counters. ♦ Collisions The number of collision errors.
