Clicking the ETHERNET tab brings up the ETHERNET STATISTICS page (Figure 5-166). The
parameters for this page are shown in Table 5-142.

Parameter Description
Index This parameter specifies the port index.
Alignment Errors
This parameter specifies the number of alignment errors. Alighment errors
generally indicate improper byte-alignment for Ethernet packets.
FCS Errors This parameter specifies the number of packets received with checksum errors.
Single Collision
Frames
This parameter specifies the number of frames received with a collision.
Multiple Collision
Frames
This parameter specifies the number of frames received with multiple collisions.
SQE Test Errors This parameter specifies the number of Signal Quality Errors that have occurred.
Deferred
Transmissions
This parameter specifies the number of frames deferred for transmissions due to
network sense.
Late Collisions
This parameter specifies the number of frames faced late collisions. A collision is
considered late if the jam occurs after 512 bit-times, or 64 bytes.
Excess Collisions
This parameter specifies the number of excess collisions detected. Excessive
Collisions describe the situation where a station has tried 16 times to transmit
without success and discards the frame. This means that there is excessive
traffic on the network and this must be reduced.
