Configuring a VA pool
A VA pool contains a group of VA interfaces. You can configure a VA pool to improve the performance of establishing or terminating L2TP connections. The LNS selects a VA interface from the pool for a requesting user and releases the VA interface when the user goes offline. When a VA pool is exhausted, the system creates a VA interface for an L2TP connection and deletes it when the user goes offline.
Configuration guidelines
When you configure a VA pool, follow these guidelines:
A VT interface can be associated with only one VA pool. To change the capacity of a VA pool, delete the previous configuration and reconfigure the VA pool.
Creating or deleting a VA pool takes time. During the process of creating or deleting a VA pool, users can come online or go offline, but the VA pool does not take effect.
The system might create a VA pool that contains VA interfaces less than the specified number because of insufficient resources. To view the number of available VA interfaces and the current state of the VA pool, use the display l2tp va-pool command.
Create a VA pool with an appropriate capacity, because a VA pool occupies much system memory.
Deleting a VA pool does not log off the users who are using VA interfaces in the VA pool.
