The port error packets fields from above are described below:
Parameter Description
Unit Allows the selection of a particular Switch in a Switch stack if you have installed the
optional stacking module and have properly interconnected the Switches.
Port Allows the selection of a particular port on the Switch.
Update Interval
<
Suspend >
The interval (in seconds) that the table is updated. The default is Suspend.
RX Frames Received packets.
CRC Error For 10 Mbps ports, the counter records CRC errors (FCS or alignment errors). For 100
Mbps ports, the counter records the sum of CRC errors and code errors (frames received
with rxerror signal).
Undersize
The total number of frames received that were less than 64 octets long (excluding framing
bits, but including FCS octets) and were otherwise well formed.
Oversize The total number of frames received that were longer than 1518 octets (excluding framing
bits, but including FCS octets) and were otherwise well formed.
Fragment The total number of frames received that were less that 64 octets in length (excluding
framing bits, but including FCS octets) and had either an FCS or an alignment error.
Jabber The total number of frames received that were longer than 1518 octets (excluding framing
bits, but including FCS octets), and had either an FCS or an alignment error.
Drop Packets The total number of events in which packets were dropped due to a lack of resources.
TX Frames Transmitted packets.
Excessive Deferral The number of frames for which the first transmission attempt on a particular interface
was delayed because the medium was busy.
CRC Error For 10 Mbps ports, the counter records CRC errors (FCS or alignment errors). For 100
Mbps ports, the counter records the sum of CRC errors and code errors (frames received
with rxerror signal).
Late Collision Late Collisions. The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
Excessive Collision Excessive Collisions. The number of frames for which transmission failed due to
excessive collisions.
Single Collision Single Collision Frames. The number of successfully transmitted frames for which
transmission is inhibited by more than one collision.
Collision An estimate of the total number of collisions on this network segment.
