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
ip icmp interval rate-mask MASK Global
Configures the interval for transmit ICMP message.
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.
