Status. Pressing SEL three times (or after 10 seconds)
will drop into a third page of Status (if available) or
return to the main PING display. If the third page is
displayed, pressing SEL once more (or another 10
seconds) will return to the main PING display.
The first step in establishing the conversations is trying
locate the router on the LAN segment. The LAN
Solution Network Tester does this using the Address
Resolution Protocol (ARP).
The tester sends out an ARP packet directed to the
router and needs a response from the router (informing
the tester of the router’s MAC address). During this
phase, “ARP” will flash under the “Rtr” acronym. If no
response to the ARP request is received, the tester will
repeat the request at varying intervals (1–3 seconds). No
response to ARP can mean that the IP address assigned
to the router is not correct, the router is non-functional,
or that it is not accessible on the LAN because of some
other problem. If you select the Rtr conversation and
press the SEL button, the status displayed is “No ARP
response.”
