Use this command to specify whether the system responds to ICMP echo request messages (pings). These messages include all ping messages: unicast, broadcast, or multicast.

Pings are a network tool that help establish the reachability of a device from the local system. Pings are often disallowed because they are a potential means of denial of service (DoS) attacks.

Use the set form of this command to enable or disable responses to pings.

Use the delete form of this command to restore the default behavior of responding to pings.

Use the show form of this command to display the state of responding to pings.
