DGS-3627:admin#
config dhcpv6 pool domain_name
Purpose
This command is used to configure the domain name for the DHCPv6 pool of the Switch.
Syntax
config dhcpv6 pool domain_name <pool_name 12> <domain_name 255>
Description
The domain name configured here will be used as the default domain name by the client.
By default, the domain name is empty. If domain name is empty, the domain name
information will not be provided to the client.
Parameters
pool <pool_name 12>
- Enter the pool name for which to set the domain name.
domain_name <domain_name 255>
- The domain name is used by client when resolving
hostnames with DNS.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the domain name for the DHCPv6 pool pool1:
DGS-3627:admin# config dhcpv6 pool domain_name pool1 d_link.com
Command: config dhcpv6 pool domain_name pool1 d_link.com
Success.
DGS-3627:admin#
config dhcpv6 pool dns_server
Purpose
This command is used to configure the DNS server’s IPv6 addresses for a specific DHCPv6
pool.
Syntax
config dhcpv6 pool dns_server <pool_name 12> <ipv6addr> {<ipv6addr>}
Description
This command is used to configure the DNS server IPv6 addresses for a specific DHCPv6
pool. Users may add up to two DNS Server addresses.
If DNS server is not specified, the DNS server information will not be provided to the client.
Users could delete a DNS server address in the method of setting the DNS server address to
zero.
For example, users first add two DNS server address: 2000::200, 2000::201, and then delete
the DNS server address 2000::200. The procedure is as followed:
Command:
config dhcpv6 pool dns_server pool1 2000::200 2000::201
config dhcpv6 pool dns_server pool1 ::
Parameters
<pool_name 12>
- Enter the pool name for which to add one or two DNS server addresses.
<ipv6addr>
- Enter the DNS server IPv6 address for this pool. Users may specify up to two
DNS server addresses.
Restrictions
Only Administrator and Operator-level users can issue this command.

config dhcpv6 pool lifetime
Purpose
This command is used to configure the preferred-lifetime and valid-lifetime of IPv6 address
within a DHCPv6 pool.
Syntax
config dhcpv6 pool lifetime <pool_name 12> preferred_lifetime <sec 60-4294967295>
valid_lifetime <sec 60-4294967295>
Description
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.
Parameters
pool <pool_name 12>
- Enter the previously created pool name for which to set the preferred-
lifetime and valid-lifetime of IPv6 address.
preferred_lifetime <sec 60-4294967295>
- The amount of time (in seconds) that the IPv6
address, based on the specified pool, remains in preferred state.
valid_lifetime <sec 60-4294967295>
- The amount of time (in seconds) that the IPv6 address,
based on the specified pool, remains in valid state.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the preferred-lifetime and valid-lifetime for the DHCPv6 pool:
DGS-3627:admin# config dhcpv6 pool lifetime pool1 preferred_lifetime 80 valid_lifetime
100
Command: config dhcpv6 pool lifetime pool1 preferred_lifetime 80 valid_lifetime 100
Success.
DGS-3627:admin#
config dhcpv6 pool manual_binding
Purpose
This command is used to configure a DHCPv6 pool manual binding entry.
Syntax
config dhcpv6 pool manual_binding <pool_name 12> [add <ipv6addr > client_duid
<string 28> | delete [<ipv6addr > | all] ]
Description
An address binding is a 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. If the user specifies a conflict IPv6 address, error message will be returned.
Parameters
pool <pool_name 12>
- Enter the name of the previously created pool that will contain the
manual binding entry.
