Switch 7700 Command reference Guide, v2.0

454 CHAPTER 11: USING SYSTEM MANAGEMENT COMMANDS
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, you can increase the response message
timeout.
For the related commands, see tracert.
Example
Check whether the host 202.38.160.244 is reachable.
<SW7700>ping 202.38.160.244
ping 202.38.160.244 : 56 data bytes
Reply from 202.38.160.244 : bytes=56 sequence=1 ttl=255 time = 1ms
Reply from 202.38.160.244 : bytes=56 sequence=2 ttl=255 time = 2ms
Reply from 202.38.160.244 : bytes=56 sequence=3 ttl=255 time = 1ms
Reply from 202.38.160.244 : bytes=56 sequence=4 ttl=255 time = 3ms
Reply from 202.38.160.244 : bytes=56 sequence=5 ttl=255 time = 2ms

Parameter
-f: Configure to verify the -f switch, first-TTL specifies an initial TTL, ranging
from 0 to the maximum TTL.
-m: Configure to verify the -m switch, max-TTL specifies a maximum TTL larger
than the initial TTL.
-p: Configure to verify the -p switch, port is an integer host port number.
Generally, user need not modify this option.
-q: Configure to verify the -q switch, nqueries is an integer specifying the
number of query packets sent, larger than 0.
