(Optional) Configuring Address Pool Protection

Configuring address pool protection includes locking an address pool, disabling IP addresses, and reclaiming IP addresses in special scenarios.

Address pool protection can be performed using the following methods:

Locking an address pool

An address pool can be locked using a command. IP addresses in a locked address pool cannot be assigned any more.

This method is usually used when an address pool cannot be deleted because an address in the pool is already used by an online user. In this case, lock the address pool so that no address can be assigned from this address pool. After all users go offline and all IP addresses in the address pool are released, delete the address pool.
Disabling IP addresses

In complex network planning, some IP addresses may need to be disabled.
IP Address Reclaiming

When an IP address in an address pool is abnormal, that is, the IP address is in use but actually no user is using it, this IP address cannot be used any more. In this case, you can run a command to forcibly reclaim the IP address.

Run system-view
The system view is displayed.
Run ip pool pool-name [ bas { local | remote } | server ]
An address pool is created and its view is displayed.
Run lock
The address pool is locked.

Alternatively, run the excluded-ip-address start-ip-address [ end-ip-address ] command to exclude an IP address or an address segment.

This command is required when you configure static IP addresses.

Alternatively, run the recycle start-ip-address [ end-ip-address ] command to reclaim an IP address or an address segment.
Run commit
The configuration is committed.
