Cisco IOS Release 12.2(20)S5
PXF Logical Interface Options
Feature History
This document describes the PXF Logical Interface Options feature introduced in Cisco IOS 
Release 12.2(20)S5. It contains the following sections:
Feature Overview
On the Cisco 7304 router using an NSE-100, the PXF processing path was enhanced in Cisco IOS 
Release 12.2(20)S5 to support up to 63 classes per QoS policy (previous Cisco IOS releases supported 
up to 23 classes per QoS policy). This enhancement, however, is only usable if the maximum number of 
PXF logical interfaces on the router is no more than 4,096. 
By default, the Cisco 7304 router using an NSE-100 supports up to 16,384 PXF logical interfaces and 
up to 23 classes per QoS policy. The enhancement introduced in Cisco IOS Release 12.2(20)S5 allows 
the router to support more traffic classes per QoS policy if desired.
The pxf max-logical-interfaces command was introduced in Cisco IOS Release 12.2(20)S5 to allow 
users to choose the number of PXF logical interfaces they would like to support on their router, thereby 
allowing them to choose the number of QoS classes they would like to support in PXF per QoS policy 
on their router.
