The NQA Internet Control Message Protocol (ICMP) test detects whether there are reachable routes from the source to the destination. It has a similar function to the ping command, but provides more output information, including:

  • Average delay
  • Packet loss ratio
  • Time the last packet was correctly received

The system saves the results of the latest five tests by default.

The ICMP test process is as follows:
  1. The source (SwitchA) constructs an ICMP Echo Request packet and sends it to the destination (SwitchB).

  2. The destination receives the ICMP Echo Request packet and responds with an ICMP Echo Reply packet.

  3. The source receives the ICMP Echo Reply packet and calculates the time between when it sent the ICMP Echo Request packet and when it received the ICMP Echo Reply packet.
