Port Statistics Screen Fields
The following explains each Port Statistics Screen field.
Port #
(Read-only)
Indicates the current port for which statistics are displayed.
Octets
(Read-only)
Displays the number of octets transmitted and received.
Packets
(Read-only)
Displays the number of packets transmitted and received.
Total Errors
(Read-only)
Displays the total number of errors on this port.
Collisions
(Read-only)
Displays the total number of collisions detected on this port.
CRC/Alignment Errors
(Read-only)
Displays the number of bad FCS (Frame Check Sequence) packets with integral
number of octets that have been received from the network. Alignment errors are
due to a bad FCS with a non-integral number of octets.
Undersize Packets
(Read-only)
Displays the number of packets received whose size was less than the minimum
Ethernet frame size of 64 bytes, not including preamble.
Oversize Packets
(Read-only)
Displays the number of packets received whose size exceeded 1518 data bytes,
not including preamble.
Fragments
(Read-only)
Displays the total number of packets received that were not an integral number of
octets in length or that had a bad Frame Check Sequence (FCS), and were less
than 64 octets in length (excluding framing bits but including FCS octets).
Jabbers
(Read-only)
Displays the number of packets received whose size exceeded 1518 data bytes,
and had a bad FCS with an integral number of octets, or a bad FCS with a non-
integral number of octets.
Broadcasts
(Read-only)
Displays the number of broadcasts transmitted and received.
