Packet Size

Users can display packets received by the Switch, arranged in six groups and classed by size, as either a line
graph or a table. Two windows are offered. To select a port to view these statistics for, select the port by using the
Port drop-down menu. The user may also use the real-time graphic of the Switch at the top of the web page by
simply clicking on a port.
To view this window, click Monitoring > Statistics > Packet Size as shown below:
Select the unit you wish to configure.
Use the drop-down menu to choose the port that will display statistics.

Counts the number of packets for which the first transmission attempt on a particular

Counts 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 packets for which transmission failed due to
excessive collisions.
Single Collision Frames. The number of successfully transmitted packets for which
transmission is inhibited by more than one collision.
An estimate of the total number of collisions on this network segment.
