For normal execution of ICMP Echo operation, the value of operation execution frequency
should be greater than the value of operation timeout.
Example of statistics output for ICMP Echo operation:
IP SLA Statistics for Index 12
Operational state of entry: Active
Type of operation: icmp-echo
Latest operation return code: OK
Latest latency value: 7 ms
Latency values:
Number of operations: 2182
Latency Min/Avg/Max: 1/6/18 ms
Number of successes: 2178
Number of failures: 4
Failed operations due to TimeOut/Unable Send/Bad Reply: 4/0/0
Failed operations due to Unreachable Net/Host/Protocol: 0/0/0
Failed operations due to Exceeded TTL/Time of reassembly: 0/0
where
Latest operation return code
: completion code of the last executed operation:
OK
: previous operation has been completed successfully.
Failed
: measurement attempt has failed.
Latest latency value
: value of the last successfully measured ICMP packet transit time.
