DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch The following fields can be set: Parameter Description Figure 11- 10. Rx Error Analysis window (table) 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. 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. 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. 242
DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch Transmitted (TX) The following graph displays error packets received by the Switch. To select a port to view these statistics for, select the port by using the Port pull-down menu. The user may also use the real-time graphic of the Switch at the top of the web page by simply clicking on a port. To view this window click Monitoring > Packets Errors > Transmitted (TX).
