Ipv6 Dhcp Client Pd - Planet SGS-6341 Series Command Manual

disabled. Only one <ipv6-prefix/prefix-length> can be configured for one prefix name.
Example:
If the prefix name my-prefix designates 2001:da8:221::/48, then the following command will add the
address 2001:da8:221:2008::2008 to interface VLAN1.
Switch(Config-if-Vlan1)# ipv6 address my-prefix 0:0:0:2008::2008/64

27.12 ipv6 dhcp client pd

Command:
ipv6 dhcp client pd <prefix-name> [rapid-commit]
no ipv6 dhcp client pd
Function:
To configure DHCPv6 prefix delegation client for the specified interface. The no form of this
command will disable the DHCPv6 prefix delegation client and remove the allocated address prefix.
Parameters:
<prefix-name> is the string with its length no more than 32, which designates the name of the
address prefix. If rapid-commit optional is specified and the prefix delegation server enables the
rapid-commit function, then the prefix delegation server will reply the prefix delegation client with the
REPLY message directly. And the prefix delegation request will be accomplished by exchanging
messages once.
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
