DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide iaid IAID lifetime VALID-LIFETIME PREFERRED-LIFETIME (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 the lifetime 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 the lifetime 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, then all the match entries will be delegated. If there are no match entries, then if there are free static entries without IAID specified and match the DUID of the message, then the match entries are replied. If the request message has no IAID option, t then if there are free static entries without IAID specified and match the DUID of the message, then the match entries are replied. If there are no match entries, the client will be delegated the prefix from the local IPv6 prefix pool specified in the IPv6 DHCP pool. Example This example shows how to configure a static binding prefix entry in a IPv6 DHCP pool named "pool1" and associates the IPv6 DHCP pool with VLAN 100. Switch# configure terminal Switch(config)# ipv6 dhcp pool pool1 Switch(config-dhcp)# prefix-delegation 2001:0DB8::/64 000300010506BBCCDDEE Switch(config-dhcp)# exit Switch(config)# interface vlan100 Switch(config-if)# ipv6 dhcp server pool1 Switch(config-if)# 28-11 prefix-delegation pool This command is used to specify a local IPv6 prefix pool from which prefixes can be delegated. Use the no form of this command to remove a local IPv6 prefix pool. prefix-delegation pool POOL-NAME [lifetime VALID-LIFETIME PREFERRED-LIFETIME] no prefix-delegation pool POOL-NAME 339
