The interface statistics page lists all network ports that are utilized by the Network Multimeter. | |||
The Interface ID is a unique number enumerated for all network ports. | The Interface status column contains generic information about each port. | ||

The Interface ID is a unique number enumerated for all network ports. | |||
The Link pair number covers two ports linked to each other in the '''bridge mode'''. | |||
That is, traffic received from one port of the same link pair will be sent to the corresponding port of the same link pair, and vice verse. In "sink mode", the link pair number is irrelevant as no traffic is forwarded. | That is, traffic received from one port of the same link pair will be sent to the corresponding port of the same link pair, and vice verse.

The Duplex status shows whether the link is operated in '''full-duplex''' or '''half-duplex''' mode. | The Duplex status shows whether the link is operated in '''full-duplex''' or '''half-duplex''' mode. | ||
In case the Allegro Network Multimeter operates in bridge mode and two mutual interfaces do not have the same link speed and duplex, a warning will be shown below the Duplex status for both interfaces. | In case the Allegro Network Multimeter operates in bridge mode and two mutual interfaces do not have the same link speed and duplex, a warning will be shown below the Duplex status for both interfaces. | ||

Next to the Interface status there are three graphs for the number of processed packets, the number of processed bytes, and possible error counters. | Next to the Interface status there are three graphs for the number of processed packets, the number of processed bytes, and possible error counters. | ||
Both packets and bytes statistics show past values in the graph and the current total values and the current rate during the last second, separately for receiving ('''yellow''' down arrow) and sending side ('''blue''' up arrow). | Both packets and bytes statistics show past values in the graph and the current total values and the current rate during the last second, separately for receiving ('''yellow''' down arrow) and sending side ('''blue''' up arrow). | ||
The error values list all possible packet processing errors. Depending on the network interface card´s capabilities, slightly different counters are shown. | The error values list all possible packet processing errors.
