IPv6 traffic passing through this switch.
Command Usage
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.
