21.19 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
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
21.20 prefix-delegation
Command: prefix-delegation <ipv6-prefix/prefix-length> <client-DUID> [iaid <iaid> ]
[lifetime <valid-time> <preferred-time> ]
no prefix-delegation <ipv6-prefix/prefix-length> <client-DUID> [iaid
<iaid> ]
Function: To configure dedicated prefix delegation for the specified user. The no form of
