This command is useful in determining if a router is sending or receiving ICMPmessages, and for troubleshooting end-to-end connections.debug ip icmp eventsSyntax: [no] debug ip icmp eventsThis command generates information about ICMP events, such as sent and received echo (ping)requests, destination-unreachable messages, and redirect messages. Command output resemblesthe following example.Brocade# debug ip icmp eventsICMP: rcvd echo request packet of length 40 from 1.1.1.2ICMP: send echo request packet of length 60 to 1.1.1.2debug ip icmp packetsSyntax: [no] debug ip icmp packetsThis command generates information about ICMP packets.
