PXF Information

---

Cisco Parallel eXpress Forwarding (PXF) is used to accelerate forwarding performance on the Cisco 7304 router. PXF is available on the NSE-100 and NSE-150 only; the NPE-G100 does not support PXF.

This appendix provides some basic information about using PXF. For more detailed information about PXF on the Cisco 7304 router, including which features are supported in PXF, restrictions, and configuration examples, see the PXF Information for Cisco 7304 Routers document.

The PXF processors are turned on by default. If they are ever disabled, you must enable them to take advantage of IP packet switching and feature acceleration.

---

Note Before enabling the PXF processors, you must have IP routing and IP CEF switching turned on.

---

To manually disable or enable the PXF processors, use the global commands:

Hostname (config)# [no] ip pxf

The following features are supported by the PXF processors and are enabled using standard IOS procedures:

•CEF—Cisco Express Forwarding

•NetFlow

•Turbo ACL—Turbo access control list

See the "Related Documentation" section to find documents about enabling these features.

PXF Troubleshooting

For PXF troubleshooting information, see the Cisco 7304 Troubleshooting module, the "PXF Feature Support" section at /en/US/docs/routers/7300/troubleshooting/7304_troubleshooting_guides/1270TSA.html#xtocid0.

Using show Commands

Use the global show version or show c7300 commands to obtain information about the hardware and software installed on your router. Examples of each follow.

Using the show version Command

Use the show version command to display the configuration of the system hardware and the software version.

The following example of the show version command identifies an NSE-100 installed in a Cisco 7304 router:

Router# show version

Using the show c7300 Command

Use the show c7300 subcommands to obtain information about the router.

•show c7300 info	Show system information
•show pxf or show c7300 pxf	Show PXF information (This command was modified to show pxf for the Cisco 7304 router. The Cisco IOS releases prior to 12.2(14)SZ that support the Cisco 7304 still require that show c7300 pxf be entered to gather PXF interface information.)
•show c7300	Show slots information
