Configuring IPv6 Interface Settings
Use the IP > IPv6 Configuration (Configure Interface) page to configure general IPv6 settings for the
selected VLAN, including auto-configuration of a global unicast interface address, explicit
configuration of a link local interface address, the MTU size, and neighbor discovery protocol
settings for duplicate address detection and the neighbor solicitation interval.

Command Usage
•
The switch must always 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 will also create a link-local address, but will not generate a
global IPv6 address if auto-configuration is not enabled. In this case, you must manually
configure an address (see
•
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.
Parameters
These parameters are displayed:
•
VLAN – ID of a configured VLAN which 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: 1-4093)
•
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 the router advertisements have the “other stateful configuration” flag set, the switch will
attempt to acquire other non-address configuration information (such as a default
gateway).
•
If auto-configuration is not selected, then an address must be manually configured using
the Add Interface page described below.
•
Enable IPv6 Explicitly – Enables IPv6 on an interface. Note that when an explicit address is
assigned to an interface, IPv6 is automatically enabled, and cannot be disabled until all
assigned addresses have been removed. (Default: Disabled)
Disabling this parameter does not disable IPv6 for an interface that has been explicitly
configured with an IPv6 address.
