Port Packet Analysis

The Web Manager allows packets received by the Switch, arranged in groups, to be viewed as
a table, as shown below.
Select the desired port using the Port drop-down menu. The Update Interval field sets the
interval at which the error statistics are updated. The user may choose intervals of 2, 5, 15, 30
and 60 seconds. Suspend will stop the updates. The default setting for this field is 2 seconds.
If the user wishes to view these statistics in a separate window from the web-based
management, click Show in new

Description
The number of frames for which the first transmission attempt on a
particular interface was delayed because the medium was busy.
Counts otherwise valid frames that did not end on a byte (octet) boundary.
Late Collisions. The number of times that a collision is detected later than
512 bit-times into the transmission of a packet.
Excessive Collisions. The number of frames for which transmission failed
due to excessive collisions.
Single Collision Frames. The number of successfully transmitted frames for
which transmission is inhibited by more than one collision.
An estimate of the total number of collisions on this network segment.
