Ipv6 Addresses; Supported Ipv6 Host Features - Cisco Catalyst 2360 Software Configuration Manual

Understanding IPv6

IPv6 Addresses

The switch supports only IPv6 unicast addresses. It does not support site-local unicast addresses, anycast
addresses, or multicast addresses.
The IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by
colons in the format: n:n:n:n:n:n:n:n. This is an example of an IPv6 address:
For easier implementation, leading zeros in each field are optional. This is the same address without
leading zeros:
You can also use two colons (::) to represent successive hexadecimal fields of zeros, but you can use this
short version only once in each address:
For more information about IPv6 address formats, address types, and the IPv6 packet header, see the
"Implementing IPv6 Addressing and Basic Connectivity" chapter of Cisco IOS IPv6 Configuration
Library on Cisco.com.

Supported IPv6 Host Features

These sections describe the IPv6 protocol features supported by the switch:

Support on the switch includes expanded address capability, header format simplification, improved
support of extensions and options, and hardware parsing of the extension header. The switch supports
hop-by-hop extension header packets, which are routed or bridged in software.
