Ping Commands

If the host does not respond, only statistics are printed. Failure to get an echo response from a host may be due to:

❑A bad physical connection

❑A non-existent or inactive host

❑Network Unreachable: no corresponding entry in the routing table

❑Destination Unreachable: the default gateway failed to route the datagram

❑Outdated ARP table information - flush the ARP table with the del-arp-entry command

If there is an active ping process due to a previous “long” ping command and you try to start a new ping, the command fails and an error message is displayed.

For example, start an endless ping to an unreachable host. No response will be received. Now try to ping an existing host. The second ping will fail because the ﬁrst one is still active.The solution is to use the ping-stop command to stop the ﬁrst active ping process.

--host 194.90.136.23 0 unreachable SYS_console>ping 194.90.136.23 0

Use CTRL-C or ping-stop to stop the ping process

SYS_console>ping 194.90.136.20 1

A ping process is active - can't start another one

SYS_console>ping-stop

PING process stopped - statistics :

ICMP	echo	requests	:	35
ICMP	echo	responses	:	0

PING process - press <CR> for prompt

SYS_console>

SYS_console>ping 194.90.136.20 1
