Setting the Switch’s IP Address (IP Version 6)
– 505 –
enabled. In this case, you must manually configure an address (see
"Configuring an IPv6 Address" on page 507 ).
◆
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.

ARAMETERS
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 IPv6
addresses 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.
◆
MTU – Sets the size of the maximum transmission unit (MTU) for IPv6
packets sent on an interface. (Range: 1280-65535 bytes;
Default: 1500 bytes)
■
The maximum value set in this field cannot exceed the MTU of the
physical interface, which is currently fixed at 1500 bytes.
■
IPv6 routers do not fragment IPv6 packets forwarded from other
routers. However, traffic originating from an end-station connected
to an IPv6 router may be fragmented.
■
All devices on the same physical medium must use the same MTU in
order to operate correctly.
