Usage Guidelines
Use this command to specify whether the system responds to broadcast ICMP echo request and broadcast ICMP time-stamp
request messages.
Pings are a network tool that help establish the reachability of a device from the local system. Pings, particularly broadcast
pings, are often disallowed because they are a potential means for denial of service (DoS) attacks. Time-stamp requests are
used to query another device for the current date and time. Time-stamp requests are also often disallowed both because they
are a potential means for a DoS attack and because the query allows an attacker to learn the date set on the queried machine.
Use the set form of this command to specify whether the system responds to broadcast ICMP ICMP echo and time-stamp
request messages.
Use the delete form of this command to restore the default behavior of not responding to broadcast ICMP ICMP echo and
time-stamp request messages.
