Chapter 4 COMMANDS FOR DHCPV6 OPTION37, 38

4.1 Commands for DHCPv6 option37, 38

4.1.1 address range

 Command: address range <start-ip> <end-ip>

 no address range <start-ip> <end-ip>

 Function: This command is used to set address range for a DHCPv6 class in DHCPv6

address pool configuration mode, the no command is used to remove the address

range. The prefix/plen form is not supported.

 Parameters: start-ip, defines the start address of the address pool

 end-ip, defines the end address of the address pool

 Default: None.

 Command Mode: DHCPv6 address pool class configuration mode

 Usage Guide: It is necessary to check the address range assigned to class in order to

make sure that it doesn’t exceed the address range of relevant address pool. A class is

assigned a single address range and the address range assigned to different class in the

same address pool can overlap. If you do not use this command to assign address range

for a DHCPv6 class, then the range for it will be the whole subnet of the address pool by

default.

 Example: Associate a DHCPv6 class named CLASS1 to dhcpv6 pool 1 and assign the

address range from 2001:da8:100:1::2 to 2001:da8:100:1::30 for CLASS1.

 Switch(Config)#ipv6 dhcp pool 1

 Switch(dhcp-1-config)#class CLASS1

 Switch(dhcp-1-class-CLASS1-config)#address range 2001:da8:100:1::2

2001:da8:100:1::30

 Command: class <class-name>

 no class <class-name>

 Function: This command associates class to address pool in DHCPv6 address pool

configuration mode and enters class configuration mode in address pool. Use the no

command to remove the link.

 Parameters: class-name, the name of DHCPv6 class.
