Ipv6 Host - Dell PowerConnect 5424 Command Line Interface Manual

User Guidelines
• Duplicate address detection verifies the uniqueness of new unicast IPv6 addresses before the addresses
are assigned to interfaces (the new addresses remain in a tentative state while duplicate address
detection is performed). Duplicate address detection uses neighbor solicitation messages to verify the
uniqueness of unicast IPv6 addresses.
• An interface returning to administratively "up" restarts duplicate address detection for all of the
unicast IPv6 addresses on the interface. While duplicate address detection is performed on the
link-local address of an interface, the state for the other IPv6 addresses is still set to TENTATIVE.
When duplicate address detection is completed on the link-local address, duplicate address detection
is performed on the remaining IPv6 addresses.
• When duplicate address detection identifies a duplicate address, the state of the address is set to
DUPLICATE and the address is not used. If the duplicate address is the link-local address of the
interface, the processing of IPv6 packets is disabled on the interface and an error message is displayed.
• All configuration commands associated with the duplicate address remain as configured while the state
of the address is set to DUPLICATE.
• If the link-local address for an interface changes, duplicate address detection is performed on the new
link-local address and all of the other IPv6 address associated with the interface are regenerated
(duplicate address detection is performed only on the new link-local address).
• Until DAD process is completed, an IPv6 address is in tentative state and can not be used for data
transfer. It is recommended to limit the configured value.
Example
The following example configures the number of consecutive neighbor solicitation messages that are
sent on an interface while duplicate address detection is performed on the unicast IPv6 addresses of the
interface to 10.
Console# Console (config)# interface g1
Console (config-if)# ipv6 nd dad attempts 10

ipv6 host

The ipv6 host Global Configuration mode command defines a static host name-to-address mapping in
the host name cache. Use the no form of this command to remove the host name-to-address mapping.
