TABLE 80 FCIP IP Ping Response Details
Field or Component Description
Status Always displays ‘Completed’. If there is a failure, an error message
displays instead of the IP Ping Result dialog box.
Packets Sent Always displays ‘4. This is not configurable.
Packets Received The number of received responses.
Packets Lost Equal to the number of packets sent minus the number of packets
received.
Packet Lost percentage The number of packets lost expressed as a percentage of the packets
sent. This will be 0%, 25%, 50%, 75% or 100% for 0, 1, 2, 3, or all 4
packets lost.
Minimum Round Trip Time The shortest time, in milliseconds, of any response. If no response, the
round trip times is 0.
Maximum Round Trip Time The longest time, in milliseconds, of any response. If no response, the
round trip times is 0.
Average Round Trip Time The average time, in milliseconds, of all responses. If no response, the
round trip times is 0.
TABLE 81
IP Ping Details
Field or Component Description
Reply From The IP address of the device that sent the reply. For a normal response,
this is the destination IP address. Some error responses (such as
"destination unreachable") may come from an intermediate router.
Status Displays either Success or an error message (such as request timed out
or destination unreachable) from the switch.
Number of bytes The number of bytes in the data portion of the response. Should be 64,
matching the 64 bytes of data sent in the transmitted packet.
Round Trip Time (ms) The time in milliseconds between sending the packet and receiving the
response. This provides a rough indication of network congestion or
latency. It is normal for the first packet to experience a higher round trip
time than later packets, if the intermediate routers need to do ARP
requests to locate the next hop.
Time To Live (hops) The number of hops remaining in the received response. The time to live
is decremented by each router that forwards the packet. The packet is
dropped if the time to live reaches zero.
