DESCRIPTION
IPv4
Select this option if you want to ping an IPv4 address, and select vlan to specify the ID
number of the VLAN to which the Switch is to send ping requests. Otherwise, select - to send
ping requests to all VLANs on the Switch.
IPv6
Select this option if you want to ping an IPv6 address. You can also select vlan and specify
the ID number of the VLAN to which the Switch is to send ping requests. Otherwise, select - to
send ping requests to all VLANs on the Switch.
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.
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
This displays the distance between the port and the location where the cable is open or
fault
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.
