Parameters: <poolname> is the name for the IPv6 address pool of the prefix delegation,
the length name string should be less than 32. <prefix/prefix-length> is the address
prefix and its length of the prefix delegation. <assigned-length> is the length of the prefix
in the address pool which can be retrieved by the client, the assigned prefix length should
be no less than the value of <prefix-length>
Command Mode: Global Mode.
Default: No IPv6 prefix delegation address pool is configured by default.
Usage Guide: This command should be used with the ―prefix delegation pool‖
command to allocate address prefixes to the clients. If IPv6 prefix delegation is removed,
the associated ―prefix delegation‖ command will be in-effective either.
16.18 lifetime
Command: lifetime {<valid-time> | infinity} {<preferred-time> | infinity}
no lifetime
Function: To configure the life time for the addresses or the address prefixes allocated by
DHCPv6. The no form of this command will restore the default setting.
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
16.19 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
