 Switch(dhcp-1-config)#domain-name test.com.cn

2.10 excluded-address

 Command: excluded-address <ipv6-address>

 no excluded-address <ipv6-address>

 Function: To configure the specified IPv6 address to be excluded from the address pool,

the excluded address will not be allocated to any hosts; the no form of this command

will remove the configuration.

 Parameter: <ipv6-address> is the IPv6 address to be excluded from being allocated to

hosts in the address pool.

 Default: Disabled

 Command Mode: DHCPv6 address pool configuration mode.

 Usage Guide: This command is used to preserve the specified address from DHCPv6

address allocation.

 Example: To configure to exclude 2001:da8:123::1 from DHCPv6 address allocation.

 Switch(config)#excluded-address 2001:da8:123::1

2.11 ipv6 address

 Command: ipv6 address <prefix-name> <ipv6-prefix/prefix-length>

 no ipv6 address <prefix-name> <ipv6-prefix/prefix-length>

 Function: To configure the specified interface to use prefix delegation for address

allocation. The no form of this command will disable the using of prefix delegation for

address allocation.

 Parameters: <prefix-name> is a string with its length no more than 32, designating or

manual configuring the name of the address prefix defined in the prefix pool. <ipv6-

prefix/prefix-length> is latter part of the IPv6 address excluding the address prefix, as

well as its length.

 Command Mode: Interface Configuration Mode.

 Default: No global address is configured for interfaces by default.

 Usage Guide: The IPv6 address of an interface falls into two parts: <prefix-name> and

<ipv6-prefix>/<prefix-length>. If routing advertisement has been enabled, the first 64

bits of the addresses will be advertised. The address generated by <prefix-name> and

<ipv6-prefix/prefix-length> combination will be removed, and the advertising of the

prefix will be 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
