# Graphing the Interface tab using EDM

Use the following procedure to view read-only information about the selected interfaces.

## Procedure steps

1. In the Device Physical View, select one or multiple ports.

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 to view information about the selected interfaces.

## Variable definitions

The following table describes the fields of Interface tab.

Field | Description
--- | ---
InOctets | Indicates the total number of octets received on the interface, including framing characters.
OutOctets | Indicates the total number of octets transmitted out of the interface, including framing characters.
InUcastPkts | Indicates the number of packets delivered by this sublayer to a higher sublayer that were not addressed to a multicast or broadcast address at this sublayer.
OutUcastPkts | Indicates the number of packets that higher-level protocols requested be transmitted that were not addressed to a multicast address at this sublayer. This total number includes those packets discarded or unsent.
InNUcastPkts | Indicates the number of packets delivered by this sublayer to a higher (sub)layer, which were addressed to a multicast or broadcast address at this sublayer.
OutNUcastPkts | Indicates the total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast or broadcast address at this sublayer, including those that were discarded or not sent.
InDiscards | Indicates the number of inbound packets that were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
OutDiscards | Indicates the number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet is 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 could not be transmitted because of errors. For character-oriented or fixed-length interfaces, the number of outbound transmission units that could not be transmitted because of errors.
InUnknownProtos | For packet-oriented interfaces, the number of packets received through the interface that were 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 were discarded because of an unknown or unsupported protocol. For an interface that does not support protocol multiplexing, this counter will always be 0.
