2-50Displaying 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.

Parameter Description
Alignment Errors The nu mber of frames received that are not an integral nu mber of octets in
length and do not pass the FCS check.
FCS Errors The number of frames re ceived that are an integral number of octet s in length
but do not pass the FCS check.
Single Collision Frames* The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
Multiple Collision
Frames*
A count of successfully transmitted frames for which transmission is inhibit ed
by more that one collision.
SQE Test Errors* A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer.
Deferred
Transmissions*
A count of frames for which the first transmission attempt on a particular
interface is delayed because the medium was busy.
Late Collisions The number of times that a collision is detected later than 51 2 bit-times into
the transmission of a packet.
