Interface Statistics (per Interface)

This window shows the interface statistics counters for the selected interface. You may set the desired interfaces numbers via the edit-boxes.

The counters are updated in real time, based on the polling interval. You can use the standard Graphics Support for the window’s counters.

The information is based on the ifTab (RFC1213 , MIB-II). The counters are described there as follows:

Input Bytes. The total number of octets received on the interface, including framing characters.

Input Unicast Packets. The number of subnetwork-unicast packets delivered to a higher-layer protocol.

Input Non-Unicast Packets. The number of non-unicast (i.e., subnetwork-broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.

Input Discarded Packets. The number of inbound packets which 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.

Input Error Packets. The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Input Unknown Protocol Packets . The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.

Output Bytes. The total number of octets transmitted out of the interface, including framing characters.

Output Unicast Packets. The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.

Output Non-Unicast Packets. The total number of packets that higher-level protocols requested be transmitted to a non-unicast (i.e., a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.

Output Discarded Packets. 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 could be to free up buffer space.

Output Error Packets. The number of outbound packets that could not be transmitted because of errors.

Output Queue Length. The length of the output packet queue (in packets).
