vlan} global configuration command, and reload the switch.
The ipv6 dhcp pool command enables the DHCPv6 pool configuration mode. These configuration
commands are available:
• address prefix IPv6-prefix: sets an address prefix for address assignment. This address must be in
hexadecimal, using 16-bit values between colons.
• lifetime t1 t2: sets a valid and a preferred time interval (in seconds) for the IPv6 address. The range
is 5 to 4294967295 seconds. The valid default is 2 days. The preferred default is 1 day. The valid
lifetime must be greater than or equal to the preferred lifetime. Specify infinite for no time interval.
• link-address IPv6-prefix: sets 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.
poolname User-defined name for the DHCPv6 pool. The pool name can be a symbolic
string (such as Engineering) or an integer (such as 0).
