Displaying Port Statistics - Alcatel OMNISTACK 6148 User Manual

Using the System Configuration Program

Displaying Port Statistics

Port Statistics display key statistics from the Ethernet-like MIB for each port. Error
statistics on the traffic passing through each port are displayed. This information can
be used to identify potential problems with the switch (such as a faulty port or
unusually heavy loading). The values displayed have been accumulated since the
last system reboot.
Select the required port. The statistics displayed are indicated in the following figure
and table.

Description
The number of frames received that are an integral number of octets in length
but do not pass the FCS check.
The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
A count of successfully transmitted frames for which transmission is inhibited
by more than one collision.
A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer.
A count of frames for which the first transmission attempt on a particular
interface is delayed because the medium was busy.
The number of times that a collision is detected later than 512 bit-times into
the transmission of a packet.
The number of frames for which transmission failed due to excessive
collisions.
The number of frames for which transmission failed due to an internal MAC
sublayer transmit error.
The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.
The number of frames received that exceed the maximum permitted frame
size.
