www.qtech.ru

 Parameters: <valid-time> and <preferred-time> are the valid life time and preferred

life time respectively for the allocated IPv6 addresses in the local address pool. Its value

is allowed to be between 1 and 31536000 in seconds, and <preferred-time> should

never be bigger than <valid-time>. The infinity parameter designates the maximum life

time.

 Command Mode: DHCPv6 Address Pool Configuration Mode.

 Default: The default valid life time and preferred life time are 2592000 seconds (30

days) and 604800 seconds (7 days) respectively.

 Example: To configure the valid life time as 1000 seconds, and the preferred life time as

600 seconds.

 Switch(config)#lifetime 1000 600

2.20 network-address

 Command: network-address <ipv6-pool-start-address> {<ipv6-pool-end-address> |

<prefix-length>} [eui-64]

 no network-address

 Function: To configure the DHCPv6 address pool; the no form of this command will

remove the address pool configuration.

 Parameters: <ipv6-pool-start-adderss> is the start of the address pool; <ipv6-pool-end-

address> is the end of the address pool; <prefix-length> is the length of the address

prefix, which is allowed to be between 3 and 128, and 64 by default, the size of the pool

will be determined by <prefix-length> if it has been specified. <ipv6-pool-end-address>

and <prefix-length> alternative options to determine the size of the IPv6 address pool.

If <prefix-length> is 64 and the eui-64 option has been configured, the DHCPv6 server

will allocate IPv6 addresses according to the EUI-64 standard, or the DHCPv6 server will

be allocating addresses sequentially.

 Default: No address pool is configured by default.

 Command Mode: DHCPv6 Address Pool Configuration Mode.

 Usage Guide: This command configures the address pool for the DHCPv6 server to

allocate addresses, only one address range can be configured for each address pool. To

be noticed, if the DHCPv6 server has been enabled, and the length of the IPv6 address

prefix has been configured, the length of the prefix in the address pool should be no

less than the length of the prefix of the IPv6 address of the respective layer three

interfaces in the switch. If <ipv6-pool-end-address> is bigger than <ipv6-pool-start-

address>, this command returns at once.

 Example: To configure the address range for address pool as 2001:da8:123::100-

2001:da8:123::200.

 Switch(dhcp-1-config)#network-address 2001:da8:123::100 2001:da8:123::200

 Relative Command: excluded-address
