MONITORING THE SWITCH

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.

Menu	Description
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	The number of successfully transmitted frames for
Frames*	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.
