View Line Chart: Clicking this button instructs the Switch to display a line graph rather than a table.
Monitoring > Errors > Received (RX)
This page displays the following graph of error packets received on 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.
Figure 4.174 - Monitoring > Errors > Received (RX) (line graph)

Figure 4.175 - Monitoring > Errors > Received (RX) (table)
The following fields can be set or viewed:
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 that 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 that 1518 octets, or if a VLAN frame is 1522 octets, and
less that 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.
