Enabling DHCPv6 Server Function

Beginning in privileged EXEC mode, follow these steps to enable the DHCPv6 server function on an
interface.
Command
Step 1
configure terminal
Step 2
ipv6 dhcp pool poolname
Step 3
address prefix IPv6-prefix lifetime {t1 t1 | infinite} (Optional) Specify an address prefix for address assignment.
Step 4
link-address IPv6-prefix

Before configuring DHCPv6, you must select a Switch Database Management (SDM) template that
supports IPv4 and IPv6.
The switch can act as a DHCPv6 client, server, or relay agent. The DHCPv6 client, server, and relay
function are mutually exclusive on an interface.
The DHCPv6 client, server, or relay agent runs only on the master switch. When there is a stack
master re-election, the new master switch retains the DHCPv6 configuration. However, the local
RAM copy of the DHCP server database lease information is not retained.
DHCPv6 Bulk Lease Query
DHCPv6 bulk-lease query allows a client to request information about DHCPv6 bindings. This
functionality adds new query types and allows the bulk transfer of DHCPv6 binding data through
TCP. Bulk transfer of DHCPv6 binding data is useful when the relay server switch is rebooted and
the relay server has lost all the binding information because after the reboot, the relay server
automatically generates a Bulk Lease Query to get the binding information from DHCP server.
DHCPv6 Relay Source Configuration
The DHCPv6 server replies to the source address of the DHCP relay agent. Typically, messages from
a DHCPv6 relay agent show the source address of the interface from which they are sent. However,
in some networks, it may be desirable to configure a more stable address (such as a loopback
interface) as the source address for messages from the relay agent. The DHCPv6 Relay Source
Configuration feature provides this capability.

Purpose
Enter global configuration mode.
Enter DHCP pool configuration mode, and define the name
for the IPv6 DHCP pool. The pool name can be a symbolic
string (such as Engineering) or an integer (such as 0).
This address must be in hexadecimal, using 16-bit values
between colons.
lifetime t1 t1—Specify a time interval (in seconds) that an
IPv6 address prefix remains in the valid state. The range is 5
to 4294967295 seconds. Specify infinite for no time interval.
(Optional) Specify a link-address IPv6 prefix.
When an address on the incoming interface or a link-address
in the packet matches the specified IPv6 prefix, the server
uses the configuration information pool.
This address must be in hexadecimal, using 16-bit values
between colons.
