Command Mode:
Interface Configuration Mode.
Default:
DHCPv6 prefix delegation client is not enabled by default.
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
25.12 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
