ip ping
Attempts to reach a specified destination by sending default ICMP echo
request packets to that destination and awaiting a response.
Valid Minimum Abbreviation
ip p
Important Considerations
■
This tool is useful for network testing, performance measurement,
and management.
■
If you need to change the default ping options, use the
ip
advancedPing
option. (The command description for
ip
advancedPing
lists the default ping options.)
■
You can either supply the host name or IP address as part of the
command string, or you can supply the information at the prompt.
■
When you specify a host name, the host name and its associated IP
address
must
be configured on a network name server. Also, you must
add the IP address on the name server to the list of name server
addresses that are associated with the network domain name. See “ip
dns domainName” earlier in this chapter for more information.
■
When the module sends an echo request packet to an IP station using
ping, the module waits for an ICMP echo reply packet. Possible
responses include:
■
If the host is reachable, the module displays information about the
ICMP reply packets and the response time to the ping.
■
If the host does not respond, the module displays the ICMP packet
information and this message:
Host is Not Responding
. It is
possible that you may not have configured your gateway IP
address.
■
If the packets cannot reach the host, the module displays the ICMP
packet information and this message:
Host is Unreachable.
A
host is unreachable when there is no route to that host.
■
To interrupt the command, press Enter.
