Graphing port interface statistics using EDM

Use this procedure to display and graph interface parameters for a port.

Procedure steps


Step Action

1

On the Device Physical View, click a port.

2

From the navigation tree, double-click Graph.

3

In the Graph tree, double-click Port.

4

In the work area, click the Interface tab.

5

On the toolbar, select a Poll Interval from the list.

6

On the toolbar, you can click Clear Counters to reset the IP statistics counters.

7

To select statistics to graph, click a statistic type row under a column heading.

8

On the toolbar, click Line Chart, Area Chart, Bar Chart, or Pie Chart.

Variable definitions

Use the data in the following table to help you understand interface statistics.

Variable Value
InOctets The total number of octets received on the interface, including framing characters.
OutOctets The total number of octets transmitted out of the interface, including framing characters.
InUcastPkts The number of packets delivered by this sublayer to a higher sublayer that are not addressed to a multicast or broadcast address at this sublayer.
OutNUcastPkts The total number of packets that higher-level protocols requested be transmitted, and that are addressed to a multicast or broadcast address at this sublayer, including those that are discarded or not sent.
InMulticastPkts The number of packets delivered by this sublayer to a higher sublayer that were addressed to a multicast address at this sublayer. For a MAC layer protocol, this number includes both group and functional addresses.
OutMulticastPkts The number of packets that higher-level protocols requested be transmitted, and that are addressed to a multicast address at this sublayer, including those that were discarded or not sent. For a MAC layer protocol, this number includes both group and functional addresses.
InBroadcastPkts The number of packets delivered by this sublayer to a higher sublayer that are addressed to a broadcast address at this sublayer.
OutBroadcastPkts The number of packets that higher-level protocols requested be transmitted, and that were addressed to a broadcast address at this sublayer, including those that were discarded or not sent.
InDiscards The number of inbound packets chosen to be discarded even though no errors were detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet can be to free up buffer space.
OutDiscards The number of outbound packets chosen to be discarded even though no errors were detected to prevent their being transmitted. One possible reason for discarding such a packet can be to free up buffer space.
InErrors For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol.
OutErrors For packet-oriented interfaces, the number of outbound packets that cannot be transmitted because of errors. For character-oriented or fixed-length interfaces, the number of outbound transmission units that cannot be transmitted because of errors.
InUnknownProtos For packet-oriented interfaces, the number of packets received through the interface that are discarded because of an unknown or unsupported protocol. For character-oriented or fixed-length interfaces that support protocol multiplexing, the number of transmission units received through the interface that are discarded because of an unknown or unsupported protocol. For any interface that does not support protocol multiplexing, this counter is always zero.
