Locking an IPv6 Address Pool

Locking an IPv6 Address Pool


When a DHCPv6 server needs to be migrated, you simply need to migrate address pools on the DHCPv6 server to another DHCPv6 server on the live network. To retain the addresses that have been assigned to clients from an address pool, you can lock the address pool. When new users go online, they apply for IPv6 addresses from the DHCPv6 server to which address pools have been migrated.


  1. Run system-view

    The system view is displayed.

  2. Run dhcpv6 pool pool-name

    An IPv6 address pool is created and the IPv6 address pool view is displayed.

    By default, no IPv6 address pool is created.

  3. Run lock

    The IPv6 address pool is locked.

    By default, no IPv6 address pool is locked.

  4. Run commit

    The configuration is committed.

Follow-up Procedure

After IPv6 address pools are migrated to another server, run the undo lock command to unlock the address pools.
