Enabling and Disabling Public Secure Packet Forwarding
Public Secure Packet Forwarding (PSPF) prevents client devices that are associated to an access point
from inadvertently sharing files or communicating with other client devices that are associated to the
access point. PSPF provides Internet access to client devices without providing other capabilities of a
LAN. This feature is useful for public wireless networks like those installed in airports or on college
campuses.
To prevent communication between clients associated to different access points, you must set up
Note
protected ports on the switch to which the wireless devices are connected. See the
Protected Ports" section on page 287
To enable and disable PSPF using command-line interface (CLI) commands on the wireless device, you
use bridge groups. You can find a detailed explanation of bridge groups and instructions for
implementing them in this document:
•
PSPF is disabled by default. To enable PSPF, follow these steps, beginning in privileged EXEC mode.
