Port Statistics Screen Fields
The following information briefly 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 packets with a bad Cyclic Redundancy Check (CRC) that
have been received from the network. The CRC is a 4-byte field in the data packet

was originally sent. Alignment errors are due to misaligned packets.

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 total number of packets received that were longer than 1518 octets
(excluding framing bits, but including Frame Check Sequence (FCS) octets), and
were not an integral number of octets in length or had a bad Frame Check
Sequence.
