Broadcasts Received—The number of frames
received that have a broadcast destination address.
This number does not include frames with errors.
Octets Received—The number of octets received by
the port, including the MAC header and CRC. Octet
counters are accurate to the nearest 256-byte bound-
ary.
Octets Transmitted—The number of octets trans-
mitted by the port, including the MAC header and
CRC. Octet counters are accurate to the nearest
256-byte boundary.
Line Errors—The total number of CRC errors that
have occurred on the port.
Frames Forwarded—The total number of frames
received by this port and then forwarded to their des-
tination address.

frames.
Lost Frames—Frame transmitted by the Switch 2000
TR which failed to make the return trip.
Abort Frames—Frames transmitted by the Switch
2000 TR that need to be aborted by transmitting an
abort delimiter.
Frame Size Analysis—A series of counters that rep-
resent the composition of the traffic on the Switch
2000 TR. The counters display the percentage of
packets that are categorized by received length as
represented by the following octet parameters:
■ 18 to 63 octets
■ 64 to 127 octets
■ 128 to 255 octets
■ 256 to 511 octets
■ 512 to 1023 octets
■ 1024 to 2047 octets
■ 2048 to 4095 octets
■ Packets greater than 4095 octets
