Utilities and Diagnostics 15-3

Status: The current status of the Ping test. This item can display the status messages shown in the able below:

Message	Description


Resolving host name	Finding the IP address for the domain name-style address

Can’t resolve host name	IP address can’t be found for the domain name–style address

Pinging	Ping test is in progress

Complete	Ping test was completed

Cancelled by user	Ping test was cancelled manually

Destination unreachable from	Ping test was able to reach the router with IP address w.x.y.z,
w.x.y.z	which reported that the test could not reach the ﬁnal
	destination

Couldn’t allocate packet buffer	Couldn’t proceed with Ping test; try again or reset system

Couldn’t open ICMP port	Couldn’t proceed with Ping test; try again or reset system

Packets Out: The number of packets sent by the Ping test.

Packets In: The number of return packets received from the target host. To be considered on time, return packets are expected back before the next packet in the sequence of Ping packets is sent. A count of the number of late packets appears in parentheses to the right of the Packets In count.

In the example that follows, a Netopia 4753 is sending Ping packets to another host, which responds with return Ping packets. Note that the second return Ping packet is considered to be late because it is not received by the Netopia 4753 before the third Ping packet is sent. The ﬁrst and third return Ping packets are on time.
