LABEL DESCRIPTION
Ping Test
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.
Count Enter the number of ICMP Echo Request (ping) messages the Switch continuously sends.
IP Address/ Type the IP address or host name of a device that you want to ping in order to test a
Host Name
connection.
Click Ping to have the Switch ping the IP address.
Trace Route Test
IPv4 Select this option if you want to trace the route packets take to a device with an IPv4
address, and select vlan to specify the ID number of the VLAN on which the Switch
traces the path. Otherwise, select - to trace the path on any VLAN.
Note: The device to which you want to run a traceroute must belong to the VLAN you
IPv6 Select this option if you want to trace the route packets take to a device with an IPv6
address.
TTL Enter the Time To Live (TTL) value for the ICMP Echo Request packets. This is to set the
maximum number of the hops (routers) a packet can travel through. Each router along
the path will decrement the TTL value by one and forward the packets. When the TTL
value becomes zero and the destination is not found, the router drops the packets and
informs the sender.
Wait Time Specify how many seconds the Switch waits for a response to a probe before running
another traceroute.
Queries Specify how many times the Switch performs the traceroute function.
IP Address/ Enter the IP address or host name of a device to which you want to perform a
Host Name
traceroute.
Click Trace Route to have the Switch perform the traceroute function. This determines
the path a packet takes to the specified device.
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.
