DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide rapid-commit preference VALUE allow-hint (Optional) Specifies to use a two-message exchange instead of the standard fourmessage exchange between the Requesting Router (RR) and the Delegating Router (DR) to obtain the network configuration settings from the DHCP Server. By default, two-message exchange is not allowed. (Optional) Specifies the preference value to be advertised by the server The range is from 0 to 255. The default value is 0. the higher the value, the higher the priority. (Optional) Specifies to delegate the prefix based on the prefix hint by the client. By default, the prefix hint by client is ignored. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command enables DHCP for IPv6 server service on a specified interface. An IPv6 DHCP pool can be associated with multiple interfaces. The pool must be configured before it can be associated. Only one IPv6 DHCP pool can be associated with an interface. The DHCP for the IPv6 client, server, and relay functions are mutually exclusive on an interface. The standard four-message exchange between the DR and the RR includes four messages: SOLICIT, ADVERTISE, REQUEST, and REPLY. When the rapid-commit parameter is specified, the RR will notify the DR in the SOLICIT message that it can skip receiving the ADVERTISE message and sending REQUEST message, and proceed directly with receiving the REPLY message from DR to complete a two-message exchange instead of the standard four-message exchange. The REPLY message contains the network configuration settings. The rapid-commit parameter must be enabled on both the DR and the RR to function properly. If the command is configured with a preference value other than 0, the preference value will be filled as option in the advertise message. An advertise message without the preference option is equivalent to having a preference value of 0. A higher preference represents a higher precedence. If the command is configured with the allow-hint option, the server will delegate the prefix based on prefix hint by client. Otherwise, the prefix hint by client is ignored. Example This example shows how to create the DHCP pool "pool1", enable the DHCP IPv6 server service on the interface VLAN 100 using the DHCP pool "pool1" to delegate the prefixes. Switch# configure terminal Switch(config)# ipv6 dhcp pool pool1 Switch(config-dhcp)# exit Switch(config)# interface vlan100 Switch(config-if)# ipv6 dhcp server pool1 Switch(config-if)# 30-9 ipv6 local pool This command is used to configure a local IPv6 prefix pool. Use the no form of this command to remove the pool. 494
