Blocking Echo Reply Message
It is possible to configure block echo reply message to the partner who is doing ping test
to switch. To block echo reply message, use the following command.
Command
ip icmp ignore echo all
ip icmp ignore echo broadcast
To release the blocked echo reply message, use the following command.
Command

no ip icmp ignore echo broad-
cast
Interval for Transmit ICMP Message
User can configure the interval for transmit ICMP message. After you configure the inter-
val, ICMP message will be blocked until the configured time based on the last message is
up. For example, if you configure the interval as 1 second, ICMP will not be sent within 1
second after the last message has been sent.
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
ip icmp interval rate-mask MASK
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
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.
