9E106-06 Module Specific Information4Interface Statistics Screen FieldsThe following information briefly explains each Interface Statistics Screen field.INTERFACE (Toggle)Allows you to select the interface you want to monitor.IN OCTETS (Read-only)Displays the number of octets (bytes) received by this interface.IN UNICAST PKTS (Read-only)Displays the number of unicast packets (packets destined for one specific address)received by this interface.IN NONUCAST PKTS (Read-only)Displays the number of non-unicast packets (multicast and broadcast packets, inother words, packets destined for more than one address) received by thisinterface.IN DISCARDS (Read-only)Displays the total number of packets discarded by this interface due to a lack ofavailable resources.IN ERRORS (Read-only)Displays the total number of errors received on this interface. The numberdisplayed is composed of one of the following errors:• Out of Window (OOW) Collision, which is one of the following:• A collision caused by a station on the network violating Carrier Sense andtransmitting at will• A cable failure occurring during the transmission of a frame• A network propagation delay greater than 51.2 ms• Cyclic Redundancy Check (CRC) Errors - Errors in the 4-byte CRC field of aframe that ensures that the data received by the module is the same as the datatransmitted by the originating device.• Alignment Errors - Alignment errors are frames that are misaligned (in otherwords, frames that contain a non-integral number of bytes).• Runt Packets - Runt packets are packets that are smaller than the minimumEthernet frame size of 64 bytes, not including preamble.• Giant Packets - Giant packets are packets that are larger than the maximumEthernet frame size of 1,518 bytes, not including preamble.
