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.
Duplicate address detection is stopped on any interface that has
■
been suspended (see
While an interface is suspended, all unicast IPv6 addresses assigned
to that interface are placed in a "pending" state. Duplicate address
detection is automatically restarted when the interface is
administratively re-activated.
An interface that is re-activated restarts duplicate address detection
■
for all unicast IPv6 addresses on the interface. While duplicate
address detection is performed on the interface's link-local address,
the other IPv6 addresses remain in a "tentative" state. If no
duplicate link-local address is found, duplicate address detection is
started for the remaining IPv6 addresses.
If a duplicate address is detected, it is set to "duplicate" state, and a
■
warning message is sent to the console. If a duplicate link-local
address is detected, IPv6 processes are disabled on the interface. If
a duplicate global unicast address is detected, it is not used. All
configuration commands associated with a duplicate address remain
configured while the address is in "duplicate" state.
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
