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 20.
Counts otherwise valid frames that did not end on a byte (octet) boundary.
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.
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.
The number of packets less than 64 bytes with either bad framing or an
invalid CRC. These are normally the result of collisions.
The number of frames with lengths more than the MAX_PKT_LEN bytes.
Internally, MAX_PKT_LEN is equal to 1522
The number of frames which are dropped by this port since the last Switch
reboot.
