DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
The following fields from above are described in more detail:
Parameter Description
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.
Fragments
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 Pkts
Late Coll.
The total number of events in which packets were dropped
due to a lack of resources.
TX Frames
Transmitted packets.
ExDefer
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 Collisions. The number of times that a collision is
detected later than 512 bit-times into the transmission of a
packet.
Ex. Coll.
Excessive Collisions. The number of frames for which
transmission failed due to excessive collisions
