Interface Statistics Screen Fields
The 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, in
other words, packets destined for more than one address) received by this
interface.
IN DISCARDS (Read-only)
Displays the total number of packets discarded by this interface due to a lack of
available resources.
IN ERRORS (Read-only)
Displays the total number of errors received on this interface. The number
displayed 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 and
transmitting 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 a
frame that ensures that the data received by the module is the same as the data
transmitted by the originating device.
• Alignment Errors - Alignment errors are frames that are misaligned (in other
words, frames that contain a non-integral number of bytes).
• Runt Packets - Runt packets are packets that are smaller than the minimum
Ethernet frame size of 64 bytes, not including preamble.
• Giant Packets - Giant packets are packets that are larger than the maximum
Ethernet frame size of 1,518 bytes, not including preamble.
