To configure interval to transmit ICMP message, the administrator should configure the type of message and the interval time.

Use the following command, to configure the interval for transmit ICMP message.

Command	Mode	Description
		Configures the interval for transmit ICMP message.
ip icmp interval rate-mask MASK	Global	MASK: user should input hexadecimal value until
		0xFFFFFFFF. The default is 0x1818.

If mask that is input as hexadecimal number is calculated as binary number “1” means “Status ON”, “0” means “Status OFF”. In binary number, if the digit showed as “1” matches with the value of ICMP message. It means ICMP Message is selected as “Status ON”. Digit value starts from 0.

For example, if hexadecimal number “8” is changed as binary number, it is “1000”. In 1000, 0 digit is “0” and 1 digit is “0”, 2 digit is “0” and 3 digit is “1”. The digit showed as “1” is “3” and ICMP_DEST_UNREACH means ICMP value is “3”. Therefore, ICMP_DEST_UNREACH is chosen the message of limiting the transmission time.

Default is 0x1818. If 1818 as hexadecimal number is changed as binary number, it is 1100000011000. By calculating from 0 digit, 3 digit, 4 digit, 11 digit, 12 digit is “1” and it is “STATUS ON”. Therefore, the message that corresponds to 3, 4, 11, and 12 is chosen as the message limiting the transmission rate.

Tab. 7.3 shows the result of mask calculation of default value.
