HPE FlexFabric 5950 Series Command Reference Manual page 303

Parameters
prefix/prefix-length: Specifies the IPv6 subnet for dynamic allocation. The value range for the
prefix-length argument is 1 to 128.
prefix prefix-number: Specifies an IPv6 prefix by its ID in the range of 1 to 1024.
sub-prefix/sub-prefix-length: Specifies an IPv6 sub-prefix and its length. The value range for the
sub-prefix-length argument is 1 to 128. If the IPv6 prefix is longer than the IPv6 sub-prefix or if you do
not specify an IPv6 sub-prefix, the IPv6 subnet defined by the IPv6 prefix is used for dynamic
allocation.
preferred-lifetime preferred-lifetime: Sets the preferred lifetime. The value range is 60 to
4294967295 seconds, and the default is 604800 seconds (7 days).
valid-lifetime valid-lifetime: Sets the valid lifetime. The value range is 60 to 4294967295 seconds,
and the default is 2592000 seconds (30 days). The valid lifetime must be longer than or equal to the
preferred lifetime.
Usage guidelines
You can specify only one subnet for a DHCPv6 address pool. If you execute the network command
multiple times, the most recent configuration takes effect.
Modifying or removing the network command configuration removes assigned addresses in the
current address pool.
The network prefix command does not take effect if the specified IPv6 prefix does not exist. This
command takes effect after the IPv6 prefix is created.
The network command defines the IPv6 subnet for dynamic allocation through the
prefix/prefix-length arguments or the prefix-number [ sub-prefix/sub-prefix-length ] arguments. The
IPv6 subnets cannot be the same in different DHCPv6 address pools.
If the prefix that the ID represents is changed, the IPv6 subnet in this command accordingly changes,
and the assigned prefix and address bindings are cleared.
Examples
# Specify the subnet 3ffe:501:ffff:100::/64 in DHCPv6 address pool 1.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] network 3ffe:501:ffff:100::/64
# Create IPv6 prefix 88:99::/32 with the prefix ID 3. Create DHCPv6 address pool 1 and use the IPv6
subnet defined by the IPv6 prefix for dynamic allocation.
<Sysname> system-view
[Sysname] ipv6 prefix 3 88:99::/32
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] network prefix 3
# Create IPv6 prefix 88:99::/32 with the prefix ID 3. Create DHCPv6 address pool 1 and use IPv6
subnet 88:99:ffff:100::/64 defined by IPv6 prefix 3 and IPv6 sub-prefix 3ffe:501:ffff:100::/64 for
dynamic allocation. The first 32 bits of the IPv6 subnet are determined by IPv6 prefix 3. The bits 33 to
64 of the IPv6 subnet are determined by the IPv6 sub-prefix and its length. The prefix length of the
IPv6 subnet is the IPv6 sub-prefix length.
<Sysname> system-view
[Sysname] ipv6 prefix 3 88:99::/32
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] network prefix 3 3ffe:501:ffff:100::/64
