Setting the Switch’s IP Address (IP Version 6)
– 532
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 switchs 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
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 IPv6 Address page described below.
Enable IPv6 Explicitly
– Enables IPv6 on an interface and assigns it a link-local
address. 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.
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: 3)
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.
