The switch must be configured with a link-local address. The switch's address
auto-configuration function will automatically create a link-local address, as
well as an IPv6 global address if router advertisements are detected on the local
interface.
The option to explicitly enable IPv6 creates a link-local address, but will not
generate a global IPv6 address if auto-configuration is not enabled. In this case,
you can manually configure a global unicast address (see
IPv6 Address" on page 461).
IPv6 Neighbor Discovery Protocol supersedes IPv4 Address Resolution Protocol
in IPv6 networks. IPv6 nodes on the same network segment use Neighbor
Discovery to discover each other's presence, to determine each other's link-
layer addresses, to find routers and to maintain reachability information about
the paths to active neighbors. The key parameters used to facilitate this process
are the number of attempts made to verify whether or not a duplicate address
exists on the same network segment, and the interval between neighbor
solicitations used to verify reachability information.
VLAN – ID of a configured VLAN that is to be used for management access. By
default, all ports on the switch are members of VLAN 1. However, the
management station can be attached to a port belonging to any VLAN, as long
as that VLAN has been assigned an IP address. (Range: 1-4094)
Address Autoconfig – Enables stateless autoconfiguration of an IPv6 address
on an interface and enables IPv6 functionality on that interface. The network
portion of the address is based on prefixes received in IPv6 router
advertisement messages, and the host portion is automatically generated
using the modified EUI-64 form of the interface identifier (i.e., the switch's MAC
address).
If a link local address has not yet been assigned to this interface, this
■
command will dynamically generate one. The link-local address is made
with an address prefix in the range of FE80~FEBF and a host portion based
the switch's MAC address in modified EUI-64 format. It will also generate a
global unicast address if a global prefix is included in received router
advertisements.
When DHCPv6 is started, the switch may attempt to acquire an IP address
■
prefix through stateful address autoconfiguration. If router advertisements
