4.3.10.3 Cable Test
The cable test feature enables you to determine the cable connection status on a
selected port. You can also obtain an estimate of the length of the cable connected to
the port, if the PHY on the ports supports this functionality.
To access this page, click System > Port > Cable Test.
Figure 4.120 System > Port > Cable Test
The following table describes the items in the previous figure.
4.3.10.4 Mirroring
Port mirroring selects the network traffic for analysis by a network analyzer. This is
done for specific ports of the switch. As such, many switch ports are configured as
source ports and one switch port is configured as a destination port. You have the
ability to configure how traffic is mirrored on a source port. Packets that are received
on the source port, that are transmitted on a port, or are both received and transmit-
ted, can be mirrored to the destination port.
Note! The cable test feature is supported only for copper cable. It is not sup-
ported for optical fiber cable.
Item Description
Interface Click the drop-down menu to select the port with the connected cable
to test.
Failure Location Dis-
tance The estimated distance from the end of the cable to the failure loca-
tion.
NOTE: This field displays a value only when the Cable Status is
Open or Short; otherwise, this field is blank.
Cable Length
(Meters) The estimated length of the cable. If the cable length cannot be deter-
mined, Unknown is displayed. This field shows the range between the
shortest estimated length and the longest estimated length.
NOTE: This field displays a value only when the Cable Status is
Normal; otherwise, this field is blank.
Cable Status Displays the cable status as one of the following:

Normal: The cable is working correctly.

Open: The cable is disconnected, or there is a faulty connector.

Open and Short: There is an electrical short in the cable.

Cable status test failed: The cable status could not be deter-
mined. The cable may in fact be working.
Test Cable Click Test Cable to perform a cable test on the selected interface. The
cable test may take up to 2 seconds to complete. If the port has an
active link, the link is not taken down, and the Cable Status always
indicates Normal. The test returns a cable length estimate if this fea-
ture is supported by the PHY for the current link speed.
NOTE: If the link is down and a cable is attached to a 10/100
Ethernet adapter, the Cable Status may indicate Open or Short
because some Ethernet adapters leave unused wire pairs
unterminated or grounded.
