Ping Host Results and Output Summary

Table 253 summarizes the output in the ping host display. If the device receives no ping responses from the destination host, review the list after Table 253 for a possible explanation.

Table 253: J-Web Ping Host Results and Output Summary

Ping Host Result

Description

bytes bytes from ip-address

  • bytes—Size of ping response packet, which is equal to the value you entered in the Packet Size box, plus 8.
  • ip-address—IP address of destination host that sent the ping response packet.

icmp_seq=0

icmp_seq=number

number—Sequence Number field of the ping response packet. You can use this value to match the ping response to the corresponding ping request.

ttl=number

number—Time-to-live hop-count value of the ping response packet.

time=time

time—Total time between the sending of the ping request packet and the receiving of the ping response packet, in milliseconds. This value is also called round-trip time.

number packets transmitted

number—Number of ping requests (probes) sent to host.

number packets received

number—Number of ping responses received from host.

percentage packet loss

percentage—Number of ping responses divided by the number of ping requests, specified as a percentage.

round-trip min/avg/max/stddev = min-time/avg-time/max-time/std-dev ms

  • min-time—Minimum round-trip time (see time=time field in this table).
  • avg-time—Average round-trip time.
  • max-time—Maximum round-trip time.
  • std-dev—Standard deviation of the round-trip times.

If the device does not receive ping responses from the destination host (the output shows a packet loss of 100 percent), one of the following explanations might apply:
