The following table describes the fields of Rmon History screen.
Field | Description |
---|---|
SampleIndex | Indicates the sample number. As history samples are taken, they are assigned greater sample numbers. |
Utilization | Estimates the percentage of a link's capacity that was used during the sampling interval. |
Octets | Indicates the number of octets received on the link during the sampling period. |
Pkts | Indicates the number of packets received on the link during the sampling period. |
BroadcastPkts | Indicates the number of packets received on the link during the sampling interval that were destined for the broadcast address. |
MulticastPkts | Indicates 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 | Indicates the number of received packets that were dropped because of system resource constraints. |
CRCAlignErrors | Indicates the number of packets received during a sampling interval that were between 64 and 1518 octets long. This length included 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 non-integral number of octets (Alignment Error). |
UndersizePkts | Indicates the number of packets received during the sampling interval were less than 64 octets long (including FCS octets, but not framing bits. |
OversizePkts | Indicates the number of packets received during the sampling interval were longer than 1518 octets (including FCS octets, but not framing bits, and were otherwise well formed. |
Fragments | Indicates the number of packets received during the sampling interval were 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 non-integral number of octets (Alignment Error). |
Collisions | Indicates the best estimate of the number of collisions on an Ethernet segment during a sampling interval. |
