The following fields can be set:
Parameter Description
Time Interval [1s ]
Select the desired setting between
1s
and
60s
, where “s” stands for
seconds. The default value is one second.
Record Number [200]
Select 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, 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.
