	DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual
The following fields can be set:
Parameter		Description
Port		Use the drop-down menu to choose the port that will display statistics.
Time Interval		Select the desired setting between 1s and 60s, where "s" stands for seconds. The default
		value is one second.
Record Number		Select number of times the Switch will be polled between 20 and 200. The default value is
		200.
CRCError		Counts otherwise valid packets that did not end on a byte (octet) boundary.
UnderSize		The number of packets detected that are less than the minimum permitted packets size of 64
		bytes and have a good CRC. Undersize packets usually indicate collision fragments, a nor-
		mal network occurrence.
OverSize		Counts valid packets received that were longer than 1518 octets and less than the
		MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1536.
Fragment		The number of packets less than 64 bytes with either bad framing or an invalid CRC. These
		are normally the result of collisions.
Jabber		Counts invalid packets received that were longer than 1518 octets and less than the
		MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1536.
Drop		The number of packets that are dropped by this port since the last Switch reboot.
Symbol		Counts the number of packets received that have errors received in the symbol on the
		physical labor.
Show/Hide		Check whether or not to display CRCError, UnderSize, OverSize, Fragment, Jabber, Drop,
		and SymbolErr errors.
Clear		Clicking this button clears all statistics counters on this window.
View Table		Clicking this button instructs the Switch to display a table rather than a line graph.
View Graphic		Clicking this button instructs the Switch to display a line graph rather than a table.
