path a packet takes to the specified device.
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.
Ethernet Port Test The slot field appears only in stacking mode. Click the drop-down list to choose the slot
number of the Switch in a stack. Enter a port number and click

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