The following statistical information is displayed:
Received Stats
■
Unicast Packets
— Displays the number of packets with a single
destination address that have been successfully received by the port.
■
Non Unicast Packets
— Displays the number of packets with a
multicast or broadcast destination address that have been received by
the port.
■
Octets
— Displays the number of octets (8 bit units) that have been
received by the port. The octets calculation includes the MAC header
and the Cyclical Redundancy Check (CRC), but excludes the
preamble/Start-of-Frame Delimiter.
■
Fragments
— Displays the number of incomplete packets that have
been received by the port; that is, the number of packets that:
■
Did not contain a whole number of octets, or had a bad Frame
Check Sequence (FCS).
■
Contained less than 64 octets (including FCS octets, but excluding
the preamble/Start-of-Frame Delimiter).
