After you select a new display mode, the statistics (and graphs, where applicable)
will refresh to reflect the current choice, as described below.
Raw Counts
The total count of network traffic received or transmitted on the indicated
interface since device counters were last reset. Raw counts are provided for the
following parameters:
In Octets Octets received on the interface, including framing
characters.
In Packets Packets (both unicast and non-unicast) received by the
device interface and delivered to a higher-layer protocol.
In Discards Packets received by the device interface that were
discarded even though no errors prevented them from
being delivered to a higher layer protocol (e.g., to free up
buffer space in the device).
In Errors Packets received by the device interface that contained
errors that prevented them from being delivered to a
higher-layer protocol.
In Unknown Packets received by the device interface that were
discarded because of an unknown or unsupported
protocol.
Out Octets Octets transmitted by the interface, including framing
characters.
Out Packets Packets transmitted, at the request of a higher level
protocol, by the device interface to a subnetwork address
(both unicast and non-unicast).
Out Discards Outbound packets that were discarded by the device
interface even though no errors were detected that
would prevent them from being transmitted. A possible
reason for discard would be to free up buffer space in the
device.
Out Errors Outbound packets that could not be transmitted by the
device interface because they contained errors.
Load
The number of bytes processed by the indicated interface during the last poll
interval in comparison to the theoretical maximum load for that interface type
(10 Mbps for standard Ethernet) . Load is further defined by the following
parameters:
In Octets The number of bytes received by this interface, expressed
as a percentage of the theoretical maximum load.
