A single configuration option is available to configure ICMP monitoring. This option is global for all analyzers used to monitor ICMP and applications using ICMP.
Unreachable Packet Mask
The ICMP error code derived from the ICMP type standard. Only packets containing this ICMP error code are counted in byte and packet statistics while analyzing data for the unreachable host. By default, this option is set to
3, which will account for the bytes and packets that cannot reach the destination network and cannot reach the destination host.
Setting this option to
0 causes ICMP packets to be unaccounted for.
