Table 4: Parameters in the output of the showipv6 dhcp binding command
Parameter Description
Address Address delegated to the indicated IAID and DUID.
See the IAID and DUID descriptions below for further information.
Prefix Prefix delegated to the indicated IAID and DUID.
See the IAID and DUID descriptions below for further information.
DUID DHCPv6 unique identifier (DUID) (see RFC 3315).
Each DHCPv6 client has as DUID. DHCPv6 servers use DUIDs to
identify clients for the association of IAs (Identity Associations) with
DHCPv6 clients. DHCPv6 clients use DUIDs to identify a DHCPv6
server.
IAID Identify Association Identifier (IAID) (see RFC 3315).
IAIDs are identifiers for IAs (Identity Associations), where an IA is a
collection of IPv6 addresses assigned to a DHCPv6 client. Each IA has
an associated IAD. Each DHCPv6 client may have more than one IA
assigned to it. Each IA holds one type of address.
preferred
lifetime
The preferred lifetime setting in seconds for the specified IAID and
DUID. Preferred IPv6 addresses or prefixes are available to interfaces
for unrestricted use and are deprecated when the preferred timer
expires. Deprecated IPv6 addresses and prefixes are available for use
and are discouraged but not forbidden. A deprecated address or
prefix should not be used as a source address or prefix, but packets
sent from deprecated addresses or prefixes are delivered as expected.
valid
lifetime
The valid lifetime setting in seconds for the specified IAID and DUID.
An IPv6 address or prefix becomes invalid and is not available to an
interface when the valid lifetime timer expires. Invalid addresses or
prefixes should not appear as the source or destination for a packet.
