In the Rmon history tab, highlight an entry and click on the Graph button. |
| The Rmon history statistics dialog box opens. |
Rmon History statistics tab fields
The following table describes the Rmon History statistics tab fields.
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
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 doe not include the broadcast packets.
DropEvents
The number of received packets that were dropped due to system resource constraints.
CRCAlignErrors
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
The number of packets received during the sampling interval were less than 64 octets long (including FCS octets, but not framing bits.
OversizePkts
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
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
The best estimate of the number of collisions on an Ethernet segment during a sampling interval.
