Show Icmp Statistics - Alcatel-Lucent OmniSwitch 6250 Cli Reference Manual

show icmp statistics

Displays Internet Control Message Protocol (ICMP) statistics and errors. ICMP is a network layer proto-
col within the IP protocol suite that provides message packets to report errors and other IP packet process-
ing information back to the source. ICMP generates several kinds of useful messages, including
Destination Unreachable, Echo Request and Reply, Redirect, Time Exceeded, and Router Advertisement
and Solicitation. If an ICMP message cannot be delivered, no second one is generated. This is to avoid an
endless flood of ICMP messages.
