FIGURE 3-29. RMON HSTORY OVERVIEW SCREEN
PARAMETER DESCRIPTION
History Index: Indicates the History index control entry.
Sample Index: Indicates the data entry index associated with the control entry.
Sample Start: The value of sysUpTime at the start of the interval over which this sample was measured.
Drop: The total number of events in which packets were dropped by the probe due to lack of resources.
Octets: The total number of octets of data (including those in bad packets) received on the network.
Pkts: The total number of packets (including bad packets, broadcast packets, and multicast packets) received.
Broadcast: The total number of good packets received that were directed to the broadcast address.
Multicast: The total number of good packets received that were directed to a multicast address.
CRCErrors: The total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64
and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment Error).
Undersize: The total number of packets received that were less than 64 octets.
Oversize: The total number of packets received that were longer than 1518 octets.
Frag.:The number of frames with size less than 64 octets received with invalid CRC.
Jabb.: The number of frames with size larger than 64 octets received with invalid CRC.
Coll.: The best estimate of the total number of collisions on this Ethernet segment.
Utilization: The best estimate of the mean physical layer network utilization on this interface during this sampling interval, in
hundredths of a percent.
