DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide 28. DHCPv6 Server Commands 28-1 address prefix This command is used to specify an address prefix for address assignment. Use the no form of this command to remove the address prefix. address prefix IPV6-PREFIX/PREFIX-LENGTH [lifetime VALID-LIFETIME PREFERRED-LIFETIME] no address prefix Parameters IPV6-PREFIX PREFIX-LENGTH lifetime VALID-LIFETIME PREFERRED-LIFETIME Specifies the IPv6 address prefix to assign to the client. Specifies the length of the IPv6 address prefix. (Optional) Specifies the valid lifetime of the address prefix in seconds. The valid lifetime value should be greater than preferred lifetime. This value must be between 60 and 4294967295, or infinite. If the lifetime is not specified, the default valid lifetime value is 2592000 seconds (30 days). (Optional) Specifies the preferred lifetime of the address prefix in seconds. This value must be between 60 and 4294967295, or infinite. If the lifetime value is not specified, the default lifetime value 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 an address prefix in an IPv6 DHCP pool configuration. Only one address prefix can be configured for a DHCPv6 pool. The latter issued command will overwrite the previous. When the server receives a request from a client, the server will check the IPv6 DHCP pool associated with the received interface. If static binding address entries are defined to assign the address for the request client, that static binding address will be assigned. Otherwise, the server will assign the address from the address prefix specified for the IPv6 DHCP pool. Example This example shows how to configure the address prefix 2001:0DB8::0/64 to the IPv6 DHCP pool "pool1". Switch# configure terminal Switch(config)# ipv6 dhcp pool pool1 Switch(config-dhcp)# address prefix 2001:0DB8::0/64 lifetime 200 100 Switch(config-dhcp)# 331
