Variable definitions

Use the data in the following table to help you understand the RMON history statistics display.

Variable Value
SampleIndex The sample number. As history samples are taken, they are assigned greater sample numbers.
Utilization Estimate the percentage of the capacity of a link that is used during the sampling interval.
Octets The number of octets received on the link during the sampling period.
Pkts The number of packets received on the link during the sampling period.
BroadcastPkts The number of packets received on the link during the sampling interval that destined for the packet address.
MulticastPkts The number of packets received on the link during the sampling interval that are destined for the multicast address. This does not include the broadcast packets.
DropEvents The number of received packets that are dropped because of system resource constraints.
CRCAlignErrors The number of packets received during a sampling interval that are between 64 and 1518 octets long. This length includes Frame Check Sequence (FCS) octets but not framing bits. The packets had a bad FCS with either an integral number of octets (FCS Error) or a nonintegral number of octets (Alignment Error).
UndersizePkts The number of packets received during the sampling interval are less than 64 octets long (including FCS octets, but not framing bits).
OversizePkts The number of packets received during the sampling interval are longer than 1518 octets (including FCS octets, but not framing bits, and are otherwise well formed).
Fragments The number of packets received during the sampling interval are less than 64 octets long (including FCS octets, but not framing bits. The packets had a bad FCS with either an integral number of octects (FCS Error) or a nonintegral number of octets (Alignment Error).
Collisions The best estimate of the number of collisions on an Ethernet segment during a sampling interval.
