The
Non-Unicast
Displays the number of packets transmitted to or received from this interface that had a destination address that is recognized by more than one device on the network segment. The multicast field includes a count of broadcast packets — those that are recognized by all devices on a segment. These statistics are displayed in the pie chart,
Discarded
Displays the number of packets which were discarded even though they contained no errors that would prevent transmission. Good packets are typically discarded to free up buffer space when the network becomes very busy; if this is occurring routinely, it usually means that network traffic is overwhelming the device. To solve this problem, you may need to
These statistics are displayed in the pie chart,
Error
Displays the number of packets received or transmitted that contained errors. These statistics are displayed in the pie chart,
Unknown Protocol (Received only)
Displays the number of packets received which were discarded because they were created under an unknown or unsupported protocol.
Packets Received (Received only)
Displays the number of packets received by the selected interface.
Transmit Queue Size (Transmit only)
Displays the number of packets currently queued for transmission from this interface. The amount of device memory devoted to buffer space, and the traffic level on the target network, determine how large the output packet queue can grow before the
Packets Transmitted (Transmit only)
Displays the number of packets transmitted by this interface.
Making Sense of Detail Statistics
The statistics available in this window can give you an idea of how an interface is performing; by using the statistics in a few simple calculations, it’s also possible to get a sense of an interface’s activity level:
To calculate the percentage of input errors:
Received Errors /Packets Received
To calculate the percentage of output errors:
