Description

 

 

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.

 

Crc Error

Counts otherwise valid packets that did not end on a byte (octet) boundary.

 

Under Size

The number of packets detected that are less than the minimum permitted packets size of 64 bytes and have a

 

Over Size

good CRC. Undersize packets usually indicate collision fragments, a normal network occurrence.

 

Counts packets received that were longer than 1518 octets, or if a VLAN frame is 1522 octets, and less than

 

Fragment

the MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1522.

 

The number of packets less than 64 bytes with either bad framing or an invalid CRC.These are normally the

 

Jabber

result of collisions.

 

The number of packets with lengths more than the MAX_PKT_LEN bytes. Internally, MAX_PKT_LEN is equal

 

Drop

to 1522.

 

The number of packets that are dropped by this port since the last Switch reboot.

 

Show/Hide

Check whether or not to display Crc Error, Under Size, Over Size, Fragment, Jabber, and Drop errors.

View Line

Chart Clicking this button instructs the Switch to display a line graph rather than a table.
