Description: A conceptual table holding the ICMP response times for various remote hosts. The table is a conceptual one in the sense that, the table actually contains no data. When a query for the table object icmpEchoReqTime is received by the agent an ICMP echo request is sent to the remote host, the ICMP echo reply is received, the elapsed time is calculated and is sent back as the response. Note that except the columnar object icmpEchoReqTime other objects in the table, viz., icmpEchoReqPktSize, icmpEchoReqTimeout and icmpEchoReqHost, have ACCESS previlege as not-accessible, those variables cannot be queried for.

The table entries have the objects icmpEchoReqPktSize, icmpEchoReqTimeout and icmpEchoReqHost as the indices, which is effectively a way of transfering these required details to the agent, so that the agent could do its function and respond appropriately.
