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.
Show/Hide: Check whether or not to display CRC Error, Under Size, Over Size, Fragment, Jabber, and
Drop errors.
Clear: Clicking this button clears all statistics counters on this window.
View Table: Clicking this button instructs the Switch to display a table rather than a line graph.
View Line Chart: Clicking this button instructs the Switch to display a line graph rather than a table.
Monitoring > Cable Diagnostics
The Cable Diagnostics is designed primarily for administrators and customer service representatives to
examine of the copper cable quality. It rapidly determines the type of cable errors occurred in the cable.
Select a port and then click the Test Now button to start the diagnosis.
Figure 5.120 - Monitoring > Cable Diagnostics
Test Result: The description of the cable diagnostic results.
•OK means the cable is good for the connection.
•Short in Cable means the wires of the RJ45 cable may be in contact somewhere.
•Open in Cable means the wires of RJ45 cable may be broken or the other end of the cable is simply
disconnected.
•Test Failed means some other errors occurred during cable diagnostics. Please select the same port and
test again.
Cable Fault Distance (meters): Indicates the distance of the cable fault from the Switch port, if the cable is
less than 2 meters, it will show “No Cable”, whether the fiber is connected to the port or not.
Cable Length (meter): If the test result shows OK, then cable length will be indicated for the total length of
the cable. The cable lengths are categorized into four types: <50 meters, 50~80 meters, 80~100 meters and
>100 meters. Deviation is +/-2 meters, therefore "No Cable" may be displayed under "Test Result," when the
cable used is less than 2 m in length. This test can only be performed when the port is up and operating at 1
Gbps.
NOTE: Cable length detection is effective on Gigabit
ports only.
The definition of cable pair is listed below:
Pair1: PIN4, PIN5
Pair2: PIN1, PIN2
Pair3: PIN3, PIN6
Pair4: PIN7, PIN8
