DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Example This example shows how to create a local IPv6 prefix pool named "prefix-pool" and use the local pool in the DHCP pool "pool1". Switch#configure terminal Switch(config)#ipv6 local pool prefix-pool 3004:DB8::/48 64 Switch(config)#ipv6 dhcp pool pool1 Switch(config-dhcp)#prefix-delegation pool prefix-pool lifetime 300 200 Switch(config-dhcp)# 27-10 prefix-delegation This command is used to specify a prefix to be delegated to the specified client. Use the no form of this command to remove the static binding prefix. prefix-delegation IPV6-PREFIX/PREFIX-LENGTH CLIENT-DUID [iaid IAID] [lifetime VALID-LIFETIME PREFERRED-LIFETIME] no prefix-delegation IPV6-PREFIX/PREFIX-LENGTH CLIENT-DUID [iaid IAID] Parameters IPV6-PREFIX PREFIX-LENGTH CLIENT-DUID iaid IAID lifetime VALID-LIFETIME PREFERRED-LIFETIME Specifies the IPv6 prefix to delegate to the specific client. Specifies the length of the IPv6 prefix. Specifies the DHCP unique identifier (DUID) of the client to get the delegation. (Optional) Specifies the identity association identifier (IAID). An IAID uniquely identifies a collection of prefixes assigned to the requesting router. (Optional) Specifies the valid lifetime of the prefix in seconds. The valid lifetime should be greater than preferred lifetime. This value must be between 60 and 4294967295, or infinite. If this parameter is not specified, the default valid lifetime is 2592000 seconds (30 days). (Optional) Specifies the preferred lifetime of the prefix in seconds. This value must be between 60 and 4294967295, or infinite. If this parameter is not specified, the default preferred lifetime is 604800 seconds (7 days). Default None. Command Mode DHCPv6 Pool Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to configure a static binding prefix entry to specify the prefix to be dedicatedly delegated to specific client. Multiple static binding prefix entry can be defined for a client, or an IAPD on a client. When the server receives a request from a client, the server will check the IPv6 DHCP pool associated with the received interface. If the request message includes the IAPD option and there are free static entries that are configured with IAID and match both the DUID and IAID of the message, all the match entries will be delegated. If there are no match entries, but there are free static entries without IAID specified and match the DUID of the 310

Example

This example shows how to create a local IPv6 prefix pool named “prefix-pool” and use the local pool in the DHCP

pool “pool1”.

Switch#configure terminal

Switch(config)#ipv6 local pool prefix-pool 3004:DB8::/48 64

Switch(config)#ipv6 dhcp pool pool1

Switch(config-dhcp)#prefix-delegation pool prefix-pool lifetime 300 200

Switch(config-dhcp)#

27-10 prefix-delegation

This command is used to specify a prefix to be delegated to the specified client. Use the

form of this command

to remove the static binding prefix.

no prefix-delegation

Parameters

IPV6-PREFIX

Specifies the IPv6 prefix to delegate to the specific client.

PREFIX-LENGTH

Specifies the length of the IPv6 prefix.

CLIENT-DUID

Specifies the DHCP unique identifier (DUID) of the client to get the delegation.

iaid

IAID

(Optional) Specifies the identity association identifier (IAID). An IAID uniquely

identifies a collection of prefixes assigned to the requesting router.

lifetime

VALID-LIFETIME

(Optional) Specifies the valid lifetime of the prefix in seconds. The valid lifetime

should be greater than preferred lifetime. This value must be between 60 and

4294967295, or infinite. If this parameter is not specified, the default valid lifetime

is 2592000 seconds (30 days).

PREFERRED-LIFETIME

(Optional) Specifies the preferred lifetime of the prefix in seconds. This value

must be between 60 and 4294967295, or infinite. If this parameter is not

specified, the default preferred lifetime is 604800 seconds (7 days).

Default

None.

Command Mode

DHCPv6 Pool Configuration Mode.

Command Default Level

Level: 12.

Usage Guideline

Use this command to configure a static binding prefix entry to specify the prefix to be dedicatedly delegated to

specific client. Multiple static binding prefix entry can be defined for a client, or an IAPD on a client.

When the server receives a request from a client, the server will check the IPv6 DHCP pool associated with the

received interface. If the request message includes the IAPD option and there are free static entries that are

configured with IAID and match both the DUID and IAID of the message, all the match entries will be delegated. If

there are no match entries, but there are free static entries without IAID specified and match the DUID of the
