60
• If the specified entry was dynamically learned through the IPv6 neighbor
discovery process, and already exists in the neighbor discovery cache, it is
converted to a static entry. Static entries in the IPv6 neighbor discovery cache
are not modified if subsequently detected by the neighbor discovery process.
• Disabling IPv6 on an interface with the no ipv6 enable command (see
page 60-2) deletes all dynamically learned entries in the IPv6 neighbor
discovery cache for that interface, but does not delete static entries.
Example
The following maps a static entry for global unicast address to a MAC address:

ipv6 nd dad attempts
This command configures the number of consecutive neighbor solicitation
messages sent on an interface during duplicate address detection. Use the no form
to restore the default setting.
Syntax
ipv6 nd dad attempts count
no ipv6 nd dad attempts
count - The number of neighbor solicitation messages sent to determine
whether or not a duplicate address exists on this interface. (Range: 0-600)
Default Setting
1
Command Mode
Interface Configuration (VLAN)
Command Usage
• 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 the vlan command on page 52-6). While an interface is
suspended, all unicast IPv6 addresses assigned to that interface are placed
