Network Connection Test Commands 451 ■ host will be treated as IP address first. If it is not an IP address, perform domain name resolution, ■ the default padding operation starts from 0x01 and ends on 0x09 (progressively), then performs again, ■ show all the information including statistics, ■ routes are not recorded, ■ send ECHO-REQUEST according to route selection, ■ default length of ECHO-REQUEST is 56 bytes., ■ default timeout of ECHO-RESPONSE is 2000ms, ■ do not display other ICMP packets (non ECHO-RESPONSE), ■ the TOS value of echo requests is 0. The ping command sends ICMP ECHO-REQUEST message to the destination. If the network to the destination works well, then the destination host will send ICMP ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST. Perform the ping command to troubleshoot the network connection and line quality. The output information includes: ■ Responses to each of the ECHO-REQUEST messages. If the response message is not received until timeout, output "Request time out". Or display response message bytes, packet sequence number, TTL and response time. ■ The final statistics, including number of sent packets, number of response packets received, percentage of non-response packets and minimal/maximum/average value of response time. If the network transmission rate is too low to increase the response message timeout. For the related commands, see tracert.

Network Connection Test Commands

host will be treated as IP address first. If it is not an IP address, perform domain
name resolution,
the default padding operation starts from 0x01 and ends on 0x09
(progressively), then performs again,
show all the information including statistics,
routes are not recorded,
send ECHO-REQUEST according to route selection,
default length of ECHO-REQUEST is 56 bytes.,
default timeout of ECHO-RESPONSE is 2000ms,
do not display other ICMP packets (non ECHO-RESPONSE),
the TOS value of echo requests is 0.
The
ping
command sends ICMP ECHO-REQUEST message to the destination. If
the network to the destination works well, then the destination host will send
ICMP ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST.
Perform the
ping
command to troubleshoot the network connection and line
quality. The output information includes:
Responses to each of the ECHO-REQUEST messages. If the response message is
not received until timeout, output "Request time out". Or display response
message bytes, packet sequence number, TTL and response time.
The final statistics, including number of sent packets, number of response
packets received, percentage of non-response packets and
minimal/maximum/average value of response time.
If the network transmission rate is too low to increase the response message
timeout.
