Viewing RMON history statistics using EDM

Use the following procedure to display Rmon History statistics.

Prerequisites

  • Open one of the supported browsers.

  • Enter the IP address of the switch to open an EDM session.

Procedure steps

  1. From the navigation tree, double-click Serviceability.

  2. In the Serviceability tree, double-click RMON.

  3. In the RMON tree, double-click Control.

  4. In the work area, select a port.

  5. In the toolbar, click Display History Data.

    The Rmon History window appears for the selected port.

Variable definitions

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.
