Setting the Switch’s IP Address (IP Version 6)
– 582 –
■
If the link-local address for an interface is changed, duplicate
address detection is performed on the new link-local address, but
not for any of the IPv6 global unicast addresses already associated
with the interface.
◆
ND NS Interval – The interval between transmitting IPv6 neighbor
solicitation messages on an interface. (Range: 1000-3600000
milliseconds;
Default: 1000 milliseconds is used for neighbor discovery operations,
0 milliseconds is advertised in router advertisements.
This attribute specifies the interval between transmitting neighbor
solicitation messages when resolving an address, or when probing the
reachability of a neighbor. Therefore, avoid using very short intervals
for normal IPv6 operations.
◆ ND Reachable-Time – The amount of time that a remote IPv6 node is
considered reachable after some reachability confirmation event has
occurred. (Range: 0-3600000 milliseconds; Default: 30000
milliseconds)
◆ Restart DHCPv6 – When DHCPv6 is restarted, the switch may attempt
to acquire an IP address prefix through stateful address
autoconfiguration. If the router advertisements have the “other stateful
configuration” flag set, the switch may also attempt to acquire other
non-address configuration information (such as a default gateway)
when DHCPv6 is restarted.
Prior to submitting a client request to a DHCPv6 server, the switch
should be configured with a link-local address using the Address
Autoconfig option. The state of the Managed Address Configuration flag
(M flag) and Other Stateful Configuration flag (O flag) received in
Router Advertisement messages will determine the information this
switch should attempt to acquire from the DHCPv6 server as described
below.
■
Both M and O flags are set to 1:
DHCPv6 is used for both address and other configuration settings.
This combination is known as DHCPv6 stateful autoconfiguration, in
which a DHCPv6 server assigns stateful addresses to IPv6 hosts.
■
The M flag is set to 0, and the O flag is set to 1:
DHCPv6 is used only for other configuration settings.
Neighboring routers are configured to advertise non-link-local
address prefixes from which IPv6 hosts derive stateless addresses.
This combination is known as DHCPv6 stateless autoconfiguration,
in which a DHCPv6 server does not assign stateful addresses to
IPv6 hosts, but does assign stateless configuration settings.
