Port Statistics
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
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.

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

transmission is inhibited by exactly one collision.
Multiple Collision

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

512 bit-times into the transmission of a packet.
