valid-lifetime valid-lifetime
: Specifies the valid lifetime for the non-temporary IPv6
addresses. The value range is 60 to 4294967295 seconds, and the default is 2592000 seconds (30
days). The valid lifetime cannot be shorter than the preferred lifetime.
Usage guidelines
If you do not specify a non-temporary IPv6 address range, all unicast addresses on the subnet
specified by the
network
command in address pool view are assignable. If you specify a
non-temporary IPv6 address range, only the IPv6 addresses in the specified IPv6 address range are
assignable.
You can specify only one non-temporary IPv6 address range in an address pool. If you execute this
command multiple times, the most recent configuration takes effect.
The non-temporary IPv6 address range specified by the
address range
command must be on the
subnet specified by the
network
command.
Examples
# Configure a non-temporary IPv6 address range from 3ffe:501:ffff:100::10 through
3ffe:501:ffff:100::31 in address pool 1.

Syntax
address-alloc-mode eui-64

The EUI-64 address allocation mode is disabled. The DHCPv6 server does not allocates IPv6
addresses based on EUI-64.

Usage guidelines
The IPv6 leases that are allocated before the command execution are not affected.
This command takes effect when the prefix length of the IPv6 subnet does not exceed 64 in the
DHCPv6 address pools.
This feature enables the DHCPv6 server to obtain the client MAC address from the link layer header
of the DHCP request and generates an EUI-64 IPv6 address for the client. If a DHCPv6 relay agent
