See Specifying the Delegated Address-Assignment Pool to Be Used for DHCPv6 Prefix
Delegation.
7. (Optional, DHCPv6 only) Enable DHCPv6 rapid commit support.
See “Enabling DHCPv6 Rapid Commit Support” on page 41.
8. (Optional, DHCPv6 only) Specify that DHCPv6 local server return DNS server addresses
as IA_NA or IA_PD suboptions rather than as a global DHCPv6 option.
See Overriding How the DNS Server Address Is Returned in a DHCPv6 Multiple Address
Environment.
9. (Optional, DHCPv6 only) Automatically log out existing client when new client solicits
on same interface.
See Automatically Logging Out DHCPv6 Clients.
10. (Optional) Specify that when the DHCP or DHCPv6 local server receives a Discover
or Solicit message that has a client ID that matches the existing client entry, the local
server deletes the existing client entry.
See DHCP Behavior When Renegotiating While in Bound State.
11. (Optional, DHCPv4 and DHCPv6) Specify that a short lease be sent to the client.
See Configuring DHCP Asymmetric Leasing.
12. (Optional, DHCPv4 and DHCPv6) Specify DHCP attributes globally or for groups.
See Configuring DHCP Attributes Outside Address Assignment Pools.
13. (Optional) Delete DHCP override settings.
See “Deleting DHCP Local Server and DHCP Relay Override Settings” on page 30.
