This switch provides statistics for the following traffic types:
◆
IPv6 – The Internet Protocol for Version 6 addresses provides a
mechanism for transmitting blocks of data (often called packets or
frames) from a source to a destination, where these network devices
(that is, hosts) are identified by fixed length addresses. The Internet
Protocol also provides for fragmentation and reassembly of long
packets, if necessary, for transmission through “small packet”
networks.
◆
ICMPv6 – Internet Control Message Protocol for Version 6 addresses is
a network layer protocol that transmits message packets to report
errors in processing IPv6 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 (that is, the next hop router) to use for a
specific destination.
◆
UDP – User Datagram Protocol provides a datagram mode of packet
switched communications. It uses IP as the underlying transport
mechanism, providing access to IP-like services. UDP packets are
delivered just like IP packets – connection-less datagrams that may be
discarded before reaching their targets. UDP is useful when TCP would
be too complex, too slow, or just unnecessary.
