when the user goes offline. When the VA pool is exhausted, the system creates VA interfaces for new 
PPPoE sessions, and removes those VA interfaces when the users go offline. 
On a VT interface, you can create one global VA pool and one regional VA pool per member device 
for interfaces bound with the VT interface.  
•  The global VA pool contains VA interfaces for logical interfaces that might span multiple 
devices, such as Ethernet aggregate interfaces.  
•  The regional VA pool contains VA interfaces for interfaces that do not span multiple devices, 
such as Ethernet interfaces.  
When you configure a VA pool, follow these guidelines: 
•  To change the capacity of a VA pool, you must delete the previous configuration, and 
reconfigure the VA pool. 
•  Creating or removing a VA pool takes time. During the process of creating or removing a VA 
pool, users can come online or go offline, but the VA pool does not take effect. 
•  If the system fails to create a VA pool because of insufficient resources, you can view the 
available resources by using the 
display pppoe-server va-pool command. 
•  VA pools are memory intensive. Set their capacity depending on your network requirements. 
•  Deleting a VA pool does not log off the users who are using VA interfaces in the VA pool. 
Examples 
# Create a VA pool with a capacity of 1000 VA interfaces on Virtual-Template 2. 
<Sysname> system-view 
[Sysname] pppoe-server virtual-template 2 va-pool 1000
