Stackable NWay Ethernet Switch User's Guide ♦ 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. ♦ Mac Rx Error The number of frames with received MAC Errors. ♦ Dropped Frames The number of frames which are dropped by this port since the last Switch reboot. ♦ Undersize Frames The number of frames detected that are less than the minimum permitted frame size of 64 bytes and have a good CRC. Undersize frames usually indicate collision fragments, a normal network occurrence. ♦ Total errors The sum of the CRC Error, Oversize Frames, Bad Fragment, Jabber, Late Collision, Mac Rx Error, Dropped Frames, and Undersize Frames counters. ♦ Collisions The number of times packets have collided on this port. Port Packet Analysis Statistics To access the fourth item on the Traffic Statistics menu, choose Port Packet Analysis Statistics. The following table appears: Figure 6-57. Packet Analysis Statistics table Select the desired device in the Switch field, the desired port in the Port field, and the desired increment setting in the Update Interval field: 5 sec, 15 sec, 30 sec, 1 min, or Suspend. Press CLEAR COUNTERS to clear all counters for a desired port. The statistic counters displayed are defined as follows: 96 Using the Console Interface
