IPv4

Select this option if you want to ping an IPv4 address, and select which traffic flow (in-
band or out-of-band) the Switch is to send ping frames.

If you select in-band, the Switch sends the frames to all ports except the management
port (labelled MGMT).

If you select out-of-band, the Switch sends the frames to the management port
(labelled MGMT).

IPv6

Select this option if you want to ping an IPv6 address. You also need to select the IPv6
interface type and specify the ID number of interface through which the Switch is to
send ping frames.

IP Address

Type the IP address of a device that you want to ping in order to test a connection.

Click Ping to have the Switch ping the IP address (in the field to the left).

Ethernet Port Test Enter a port number and click Port Test to perform an internal loopback test.

Cable Diagnostics

Enter a port number and click Diagnose to perform a physical wire-pair test of the
Ethernet connections on the specified port(s). The following fields display when you
diagnose a port.

Port

This is the number of the physical Ethernet port on the Switch.

Channel

An Ethernet cable usually has four pairs of wires. A 10BASE-T or 100BASE-TX port only
use and test two pairs, while a 1000BASE-T port requires all four pairs.

This displays the descriptive name of the wire-pair in the cable.

Pair status

Ok: The physical connection between the wire-pair is okay.

Open: There is no physical connection (an open circuit detected) between the wire-pair.

Short: There is an short circuit detected between the wire-pair.

Unknown: The Switch failed to run cable diagnostics on the cable connected this port.

Unsupported: The port is a fiber port or it is not active.

Cable length

This displays the total length of the Ethernet cable that is connected to the port when the
Pair status is Ok and the Switch chipset supports this feature.

This shows N/A if the Pair status is Open or Short. Check the Distance to fault.

This shows Unsupported if the Switch chipset does not support to show the cable
length.

Distance to

fault

This displays the distance between the port and the location where the cable is open or
shorted.

This shows N/A if the Pair status is Ok.

This shows Unsupported if the Switch chipset does not support to show the distance.
