PXF Information
The PXF processor is turned on by default. If it is ever disabled, you must enable it to take advantage of
IP packet switching and feature acceleration.
Note The VPN Acceleration Module (VAM) is not compatible with the PXF processor.
Note Before enabling the PXF processor, you must have IP routing and IP CEF switching turned on.
To manually disable or enable the PXF processor, use the global commands:
hostname (config)# [no] ip pxf
The following features are supported by the PXF processor and are enabled using standard IOS
procedures:
• CEF—Cisco Express Forwarding
• NetFlow

• WFQ—weighted fair queuing
• WRED—weighted random early detection
• ACL—access control list
• CBWRED—class-based weighted random early detection

See the “Related Documentation” section on page xvii to find documents about enabling these features.
