Time Interval [1s ] – Select the desired setting between 1s and 60s, where “s” stands for

seconds. The default value is one second.

Record Number [200 ]– Select number of times the Switch will be polled between 20 and 200.

The default value is 200.

CRCError – Counts otherwise valid frames that did not end on a byte (octet) boundary.

UnderSize – The number of frames detected that are less than the minimum permitted frame

size of 64 bytes and have a good CRC. Undersize frames usually indicate collision fragments, a
normal network occurrence.

OverSize – Counts packets received that were longer than 1518 octets, or if a VLAN frame,

1522 octets and less than the MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1522.

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 – The number of frames with lengths more than the MAX_PKT_LEN bytes. Internally,

MAX_PKT_LEN is equal to 1522.

Drop – The number of frames which are dropped by this port since the last Switch reboot.

Show/Hide – Check whether or not to display CrcError, UnderSize, OverSize, Fragment,

Jabber, and Drop 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 Line Chart – Clicking this button instructs the Switch to display a line graph rather than a
