Ping Commands
7-2
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Outdated ARP table information - flush the ARP table with the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
SYS_console>
SYS_console>ping 194.90.136.20 1
