Command Mode: Interface Configuration Mode.
Default: DHCPv6 address pool based on port is not configured by default.
Usage Guide: This command configure the DHCPv6 address pool which is applied by the
DHCPv6 server for the specified interface, as well as optional parameters. One VLAN can
bind many DHCPv6 address pools and assign the address for DHCPv6 request packet
from direct-link and relay delegation.
Example:
Switch(Config-if-Vlan1)#ipv6 dhcp server PoolA preference 80 rapid-commit allow-hint
16.16 ipv6 general-prefix
Command: ipv6 general-prefix <prefix-name> <ipv6-prefix/prefix-length>
no ipv6 general-prefix <prefix-name>
Function: To define an IPv6 general prefix. The no form of this command will delete the
configuration.
Parameter: <prefix-name> is a character string less than 32 characters, to use as IPv6
general prefix name. <ipv6-prefix/prefix-length> is defined as IPv6 general prefix.
Command Mode: Global Mode.
Default: IPv6 general prefix is not configured by default.
Usage Guide: If IPv6 general prefix is configured, the interface will use the configured
prefix for IPv6 address generating. Commonly, the general prefix is used for enterprise
IPv6 prefix, and when entering an IPv6 address, users can simply add the address suffix
of to the name of the general prefix. The configured address prefix will be reserved in the
general address prefix pool. At most 8 general prefix can be configured at the same time.
When trying to remove a configured general prefix name, the operation will fail if any
interfaces used the configured prefix. Only one general prefix for a prefix name. The
general prefix can not use the same prefix definition with prefixes learnt from prefix
delegation.
Example: To set the prefix of 2001:da8:221::/48 to general prefix my-prefix.
Switch(config)# ipv6 general-prefix my-prefix 2001:da8:221::/48
16.17 ipv6 local pool
Command: ipv6 local pool <poolname> <prefix/prefix-length> <assigned-length>
no ipv6 local pool <poolname>
Function: To configure the address pool for prefix delegation. The no form of this
command will remove the IPv6 prefix delegation configuration.
