lock drain(IPv6 address pool view)
Function
The lock drain command locks an IP address pool so that the renew packets sent by online users in the address pool and the rebind packets sent at 7/8 of the lease periods. In the through packet phase, the device discards the solicit and request packets of online users.
The undo lock drain command unlocks an IP address pool.
By default, no address pool is locked.
This command is supported only on the NetEngine 8000 F1A.
Usage Guidelines
Usage Scenario
This command is supported only on the admin VS.
The lock drain command does not take effect for PPPoE users or ND users in remote address pool scenarios. For a remote BAS address pool, if the undo dhcp-proxy enable command is run in the BAS interface view, the device directly sends Renew or Rebind messages from clients to the DHCPv6 server instead of processing the messages. In this case, the lock drain command does not take effect for the remote BAS address pool. The lock drain and lock commands are mutually exclusive. Users whose IP addresses are delivered by the RADIUS server from a locked address pool are not allowed to go online or renew the lease.Configuration Impact
