21 Configuring ICMP Objects

The Internet Control Message Protocol (ICMP), defined in RFC 792, is a protocol used to determine whether a destination is unreachable. A TCP/IP-based protocol, ICMP verifies, through error and control messages between a host and an Internet gateway, the validity of an IP address. For example, ICMP functions are used by ping utilities to verify network connectivity. You configure ICMP for each IP interface that requires the functionality.

Default: enabled
Values: enabled | disabled

limit: Limits the number of ICMP packets that can be received per second on this IP interface.

Default: 10
