TABLE 38 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.
