Chapter 8 Application Table 89 RMON > History > Graph View LABEL DESCRIPTION View Network Utilization Utilization Select this to display the network utilization status in percentage (%) collected by the port. View Octets Octets Select this to display the total number of octets received/transmitted on the port. View Packets Data Total Packets Select this to display the total number of all good packets received/transmitted on the port. Drop Event Select this to display the total number of packets that were dropped by the port. Broadcast Packets Select this to display the total number of good broadcast packets received/transmitted on the port. Multicast Packets Select this to display the total number of good multicast packets received/transmitted on the port. Unicast Packets Select this to display the total number of good unicast packets received/transmitted on the port. Undersize Packets Select this to display the number of packets dropped by the port because they were less than 64 octets long, and contained a valid FCS. Fragments Select this to display the number of packets received/transmitted on the port because they were less than 64 octets long, and contained an invalid FCS, including non-integral and integral lengths. Oversize Packets Select this to display the number of packets dropped by the port because they were longer than 1518 octets and contained an invalid FCS, including alignment errors in the graph of this section. Jabbers Select this to display the number of packets received/transmitted on the port because they were longer than 1518 octets (non VLAN) or 1522 octets (VLAN) and contained an invalid FCS, including alignment errors. Collisions Select this to display the number of packets for which transmission failed due to collisions. Excessive collision is defined as the number of maximum collisions before the retransmission count is reset. CRC Align Error Select this to display the number of frames received/transmitted on the port because they were 64 to 1518 (non VLAN) or 1522 (VLAN) octets long but contained an invalid FCS and a non-integral number of octets.
