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.

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		A count of successfully transmitted frames for which transmission is inhibited
Frames*		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		A count of frames for which the first transmission attempt on a particular
Transmissions*		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.
