Setting the Switch’s IP Address (IP Version 6)
network segment, and the interval between neighbor solicitations used
to verify reachability information.
P
ARAMETERS
These parameters are displayed in the web interface:
◆
VLAN – ID of a configured VLAN which is to be used for management
access, or as a standard interface for a subnet. 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 – This configuration option is not supported for
Layer 3 routers.
◆
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 by this command cannot exceed the MTU of
the physical interface, which is currently fixed at 1500 bytes.
■
If a non-default value is configured, an MTU option is included in the
router advertisements sent from this device. This option is provided
to ensure that all nodes on a link use the same MTU value in cases
where the link MTU is not otherwise well known.
■
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.
■
IPv6 must be enabled on an interface before the MTU can be set. If
an IPv6 address has not been assigned to the switch, “N/A” is
displayed in the MTU field.
◆
ND DAD Attempts – The number of consecutive neighbor solicitation
messages sent on an interface during duplicate address detection.
(Range: 0-600, Default: 2)
■
Configuring a value of 0 disables duplicate address detection.
■
Duplicate address detection determines if a new unicast IPv6
address already exists on the network before it is assigned to an
interface.
■
Duplicate address detection is stopped on any interface that has
been suspended (see
"Configuring VLAN Groups" on page 164 ).
