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. |
