Command Reference Guide

If the above parameters have not been specified, the following default settings
will be used:
■
the ECHO-REQUEST packet is sent for 5 times at most.
■
the Socket is non-DEBUG mode.
■
the Host is first regarded as an IP address. If it is not an IP address,
domain name resolution will be performed.
■
the filling begins at 0x01 and increases gradually until 0x09 and then
repeats.
■
All the information including statistics is displayed.
■
the Router is not recorded.
■
the length of ECHO-REQUEST packet is 56 bytes.
■
the timeout time waiting for an ECHO-RESPONSE packet is 2000ms.
■
the ICMP packets other than ECHO-RESPONSE packets are not
displayed.
■
the parameter vpn-instance is not defined.
Following is the process of executing the
ping
command:
■
A host sends an ICMP ECHO-REQUEST to a destination. If the connection
to the destination network is working normally, the destination host will be
able to receive the ICMP ECHO-REQUEST packet and send an ICMP
ECHO-REPLY packet back to the source host.
■
The
ping
command can be used to test the network for connection failure
or network line quality problem. The output information includes:
■
The state of the reply that a destination has made to each ECHO-
REQUEST. It will be “Request time out." if no reply has been received
upon the expiration of the timeout time. Otherwise, the state information
will include the bytes of the reply packet, packet sequence number, TTL,
reply time etc.
■
The last statistic information includes the count of packets sent, the count
of reply packets received, the percentage of the packets that have no reply,
and the minimum, maximum, and average reply time settings.
■
If the network transmission is slow, you can appropriately prolong the
timeout time waiting for reply.
