Description
Use the drop-down menu to choose the port that will display statistics.
Select the desired setting between 1s and 60s, where "s" stands for seconds. The default
value is one second.
Select number of times the Switch will be polled between 20 and 200. The default value is
200.
Counts otherwise valid packets that did not end on a byte (octet) boundary.
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 nor-
mal network occurrence.
Counts valid packets received that were longer than 1518 octets and less than the
MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1536.
The number of packets less than 64 bytes with either bad framing or an invalid CRC. These
are normally the result of collisions.
Counts invalid packets received that were longer than 1518 octets and less than the
MAX_PKT_LEN. Internally, MAX_PKT_LEN is equal to 1536.
The number of packets that are dropped by this port since the last Switch reboot.
Counts the number of packets received that have errors received in the symbol on the
physical labor.
