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.

physical labor.
