Commands for DHCPv6
321
Usage Guide: This command is used to configure the prefix delegation client on the
specified interface, an interface with prefix delegation client enabled will send SOLICIT
packets to try to get address prefix from the server. If the prefix is retrieved correctly, the
address prefix in the global address pool can be used by the ipv6 address command to
generate a valid IPv6 address. This command is exclusive with ipv6 dhcp server and
ipv6 dhcp relay destination. If the prefix delegation client is disabled for an interface,
then the address prefix which is get from this interface through prefix delegation client,
will be removed from the global address pool. Also the interface address which is
generated by the prefix delegation client will be removed, and routing advertisement with
the prefix will be disabled. If any general prefix has been configured by the ipv6
general-prefix command, the same prefix learnt from prefix delegation will be
disagreed.
Example:
Switch(Config-if-Vlan1)#ipv6 dhcp client pd ClientA rapid-commit
27.13 ipv6 dhcp client pd hint
Command: ipv6 dhcp client pd hint <prefix|prefix-length>
no ipv6 dhcp client pd hint <prefix|prefix-length>
Function: Designate the prefix demanded by the client and its length. The no operation
of this command will delete that prefix and its length from the specified interface.
Parameters: <prefix|prefix-length> means the prefix demanded by the client and its
length.
Command Mode: Interface Configure Mode.
Default Settings: There is no such configuration in the system by default.
Usage Guide: The system designates a prefix and its length on the interface for a client.
If client prefix-proxy demanding function is enabled on the interface and hint function is
enabled on the switch, the user will have prior claim to the prefix it demands and the
prefix length when the server allocates them. Only one hint prefix is allowed in the
system.
Examples:
Switch(vlan-1-config)#ipv6 dhcp client pd hint 2001::/48
