Use the Port Statistics menu to display Etherlike or RMON statistics for 
any port on the switch. The statistics displayed are indicated in the 
following figure and table.

Etherlike 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). Values 
displayed have been accumulated since the last system reboot.

Alignment Errors

The number of alignment errors (mis-synchronized data 

packets). 

FCS Errors

The number of frames received that are an integral number 

of octets 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 inhibited by more than 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 

512 bit-times into the transmission of a packet.
