ICMP C
OMMANDS
Overview
This section describes the ICMP (Internet Control Message Protocol) commands
accessible from the CLI. In TCP/IP, ICMP the collection of messages exchanged by
IP modules in both hosts and gateways to report errors, problems and operating
information.
The protocol is used to report problems with delivery of IP datagrams within an IP
network. It can be used to show when a particular remote site is not responding,
when an IP network is not reachable, when a node is overloaded, when an error
occurs in the IP header information, etc. The protocol is also frequently used to
verify correct operations of remote sites and to check that routers are correctly
routing packets to the specified destination address.
The following table identifies the ICMP commands described in this chapter:
