Chapter 8 Application Table 88 RMON > History > Table View LABEL DESCRIPTION Fragments This is the number of packets received/transmitted on the port or interface because they were less than 64 octets long, and contained an invalid FCS, including non-integral and integral lengths since the last sample time. Jabbers This is the number of packets received/transmitted on the port or interface because they were longer than 1518 octets (non VLAN) or 1522 octets (VLAN) and contained an invalid FCS, including alignment errors since the last sample time. Collisions This is the number of packets for which transmission failed due to collisions since the last sample time. Excessive collision is defined as the number of maximum collisions before the retransmission count is reset. Utilization (%) This field displays the mean physical layer network utilization (in hundredths of a percent) on this port or interface during this sampling interval.
