ping
This command sends (IPv4) ICMP echo request packets to another node on the
network.
Syntax
ping host [size size] [count count]
• host - IP address or IP alias of the host.
• size - Number of bytes in a packet. (Range: 32-512, default: 32)
The actual packet size will be eight bytes larger than the size specified
because the router adds header information.
• count - Number of packets to send. (Range: 1-16, default: 5)
Default Setting
size: 32 bytes
count: 5
Command Mode
Normal Exec, Privileged Exec
Command Usage
• Use the ping command to see if another site on the network can be reached.
• The following are some results of the ping command:
- Normal response - The normal response occurs in one to ten seconds,
depending on network traffic.
- Destination does not respond - If the host does not respond, a “timeout”
appears in ten seconds.
- Destination unreachable - The gateway for this destination indicates that
the destination is unreachable.
- Network or host unreachable - The gateway found no corresponding entry
in the route table.
• When pinging a host name, be sure the DNS server has been enabled (see
page 38-5). If necessary, local devices can also be specified in the DNS static
host table (see page 38-1).
