Chapter 15 Configuring Access Control
We recommend that you use the default MAC address that is provided by the MAC address PROM. When
you specify your own MAC address using the set pbf mac command, if the MAC address is a duplicate
of a MAC address that is already in use, some packets might get dropped.
To display the PBF status and the MAC address, perform this task in privileged mode:
Task
Display the PBF status and the MAC address.
To enable PBF, perform one of these tasks in privileged mode:
Task
Enable PBF with a default MAC address.
Enable PBF with a specific MAC address.
This example shows how to check the PBF status and the MAC address, enable PBF with a default MAC
address, and verify the change:
Console> (enable) show pbf
Pbf status
-----------

Console> (enable)
Console> (enable) set pbf
PBF committed successfully.
Operation successful.
Console> (enable)
Console> (enable) show pbf

This example shows how to enable PBF with a specific MAC address:
Console> (enable) set pbf mac 00-11-11-11-11-11
PBF committed successfully.
Operation successful.
Console> (enable)
Console> (enable) show pbf
