DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide
•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 table.
