Cisco Cisco IOS Software Release 12.4(22)XR Références techniques

To limit the number of Asynchronous High-Level Data Link Control (AHDLC) channel resources 
provided by the AHDLC engine, use the cdma pdsn a10 ahdlc engine command in global configuration 
mode. To reset the number of AHDLC channel resources to the default, use the no form of this command.

cdma pdsn a10 ahdlc engine slot usable-channels usable-channels

no cdma pdsn a10 ahdlc engine slot usable-channels

The default number of usable channels equals the maximum channels supported by the engine; the c-5 
images supports 8000 sessions, and all c-6 image support 20000 sessions. 

In the PDSN 4.0 image, the maximum number of usable channel is increased to 75000. 

In the PDSN 5.0 image, the maximum number of usable channel is increased to 105000 per processor.

Global configuration.

If the value of usable-channels is greater than default maximum channels provided by the engine, the 
command fails.

The command also fails when the engine has any active channels.

The following example shows how to limit the number of service channels provided by the AHDLC 
engine to 1000:

cdma pdsn a10 ahdlc engine 0 usable-channels 1000

Slot number of the AHDLC.

usable-channels

Maximum number of channels that can be opened in the AHDLC engine. 
Valid values range between 0 and 8000 or 20000. Specifying 0 disables the 
engine.
