xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Figure 8- 15. RX Error Analysis window (table) 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 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 good CRC. Undersize packets usually indicate collision fragments, a normal network occurrence. Over Size Counts packets received that were longer than the MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1536 octets, or if a VLAN frame of 1540 octets was received. 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 Counts the error packets that were received that exceeded 1518 bytes, or for VLAN frames, 1522 bytes, and less than the MAX_PKT_LEN. The MAX_PKT_LEN is equal to 1536 bytes, and 1540 bytes for a VLAN frame. Drop The number of packets that are dropped by this port since the last Switch reboot. Symbol Counts the number of packets received that have errors received in the symbol on the physical labor. BuFullDr Incremented for each packet that is discarded while the input buffer is full. ACLDr Incremented for each packet that is denied by ACLs. 427
