24-7 config dhcpv6 pool lifetime
Description
This command is used to configure the preferred-lifetime and valid-lifetime of IPv6 address within a
DHCPv6 pool.
Preferred lifetime - the length of time that a valid address is preferred (i.e., the time until
deprecation). When the preferred lifetime expires, the address becomes deprecated.
Valid lifetime - the length of time an address remains in the valid state (i.e., the time until
invalidation). When the valid lifetime expires, the address becomes invalid.
The valid lifetime must be greater than or equal to the preferred lifetime.
Format
config dhcpv6 pool lifetime <pool_name 12> preferred_lifetime <sec 60-4294967295>
valid_lifetime <sec 60-4294967295>
Parameters
<pool_name 12>
- Enter the DHCPv6 pool name used here. This name can be up to 12
characters long.
preferred_lifetime - Specifies the length of time that a valid address is preferred to.
<sec 60-4294967295> - Enter the preferred lifetime value here. This value must be between
60 and 4294967295 seconds.

24-8 config dhcpv6 pool manual_binding
Description

mapping between the IPv6 address and DUID (A DHCPv6 Unique Identifier for a DHCPv6
participant) of a client. The IPv6 address specified in the manual binding entry must be in the
range of the DHCPv6 pool.
