Enabling and Disabling Public Secure Packet Forwarding
A Cisco Aironet Workgroup Bridge provides a wireless LAN connection for up to eight
Ethernet-enabled devices.
Beginning in privileged EXEC mode, follow these steps to configure the encapsulation transformation
method:
Use the no form of the command to disable reliable multicast messages to workgroup bridges.
Enabling and Disabling Public Secure Packet Forwarding
Public Secure Packet Forwarding (PSPF) prevents client devices associated to an access point from
inadvertently sharing files with other client devices on the wireless network. It provides Internet access
to client devices without providing other capabilities of a LAN. With PSPF enabled, client devices
cannot communicate with other client devices on the wireless network. This feature is useful for public
wireless networks like those installed in airports or on college campuses.
To enable and disable PSPF using IOS commands, you use bridge groups. You can find a detailed
explanation of bridge groups and instructions for implementing them in this document:
