12.10 Configuring ICMP Messages
Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet
Protocol suite. It is used by network devices such as routers to send error messages
indicating, for example, that a requested service is unavailable.
You can configure the device to handle ICMP messages as follows:
Send and receive ICMP Redirect messages.
Send ICMP Destination Unreachable messages. The device sends this message in
response to a packet that cannot be delivered to its destination for reasons other than
congestion. The device sends a Destination Unreachable message upon any of the
following:
• Address unreachable
• Port unreachable
This feature is applicable to IPv4 and IPv6 addressing schemes.
The following procedure describes how to configure ICMP messaging through the Web
interface. You can also configure it through ini file - DisableICMPUnreachable (ICMP
Unreachable messages) and DisableICMPRedirects (ICMP Redirect messages).
To configure handling of ICMP messages:
1. Open the Network Settings page (Setup menu > IP Network tab > Advanced folder >
Network Settings).
Figure 12-13: Configuring ICMP Messaging
2. Under the ICMP group, do the following:
• To enable sending and receipt of ICMP Redirect messages, configure the 'Send
and Received ICMP Redirect Messages' parameter to Enable.
• To enable sending of ICMP Destination Unreachable messages, configure the
'Send ICMP Unreachable Messages' parameter to Enable.
3. Click Apply.
