CONFIGURING THE SWITCH

ICMP Statistics

Internet Control Message Protocol (ICMP) is a network layer protocol that transmits message packets to report errors in processing IP packets. ICMP is therefore an integral part of the Internet Protocol. ICMP messages may be used to report various situations, such as when a datagram cannot reach its destination, when the gateway does not have the buffering capacity to forward a datagram, and when the gateway can direct the host to send traffic on a shorter route. ICMP is also used by routers to feed back information about more suitable routes (i.e., the next hop router) to use for a specific destination.

Statistical Values

Parameter	Description
Messages	The total number of ICMP messages which the entity
	received/sent.

Errors	The number of ICMP messages which the entity
	received/sent but determined as having ICMP-specific
	errors (bad ICMP checksums, bad length, etc.).

Destination	The number of ICMP Destination Unreachable
Unreachable	messages received/sent.

Time Exceeded	The number of ICMP Time Exceeded messages
	received/sent.

Parameter Problems	The number of ICMP Parameter Problem messages
	received/sent.

Source Quenches	The number of ICMP Source Quench messages
	received/sent.

Redirects	The number of ICMP Redirect messages received/sent.

Echos	The number of ICMP Echo (request) messages
	received/sent.

Echo Replies	The number of ICMP Echo Reply messages received/
	sent.

Timestamps	The number of ICMP Timestamp (request) messages
	received/sent.
