In addition to the icmp type command, several commonly used ICMP messages have been separate CLI
commands for convenience. These commands are listed below with the ICMP message name, type, and
code:
These commands are entered as the icmp type command, without specifying a type or code only. The
echo, timestamp, and address mask commands have the options for distinguishing between a request or a
reply, and the unreachable command has options distinguishing between a network, host, protocol, or port.
For example, to enable an echo request message, enter the following:
-> icmp echo request enable
To enable a network unreachable message, enter the following:
-> icmp unreachable net-unreachable enable
See Chapter 1, “IP Commands,” for specifics on the ICMP message commands.
Enabling All ICMP Types
To enable all ICMP message types, use the icmp messages command with the enable keyword. For
example:
-> icmp messages enable
To disable all ICMP messages, enter the same command with the disable keyword. For example:
-> icmp messages enable
