The following fields can be set:
Parameter | 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 the number of times the Switch will be polled between 20 and 200. The default |
|
|
| value is 20. |
|
|
|
|
|
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 normal network occurrence. |
|
|
|
|
|
OverSize |
| Counts packets received that were longer than 1518 octets, or if a VLAN frame is |
|
|
| 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 packets with lengths more than the MAX_PKT_LEN bytes. Internally, |
|
|
| MAX_PKT_LEN is equal to 1522. |
|
|
|
|
|
Drop |
| 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. |
