DETAILED STEPS
Use the no form of the bridge group command to disable PSPF.
Configuring Protected Ports
To prevent communication between client devices that are associated to different access points on your
wireless LAN, you must set up protected ports on the switch to which the wireless devices are connected.
To define a port on your switch as a protected port, follow these steps, beginning in privileged EXEC
mode.
SUMMARY STEPS
1. configure terminal
2. interface interface-id
3. switchport protected
4. end
5. show interfaces interface-id switchport
6. copy running-config startup-config
DETAILED STEPS
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
interface dot11radio {0| 1} Enters interface configuration mode for the radio interface. The
802.11g/n 2.4-GHz radio is radio 0.
The 802.11n 5-GHz radio is radio 1.
Step 3
bridge-group group port-protected Enables PSPF.
Step 4
end Returns to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Saves your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
interface interface-id Enters interface configuration mode. Enter the type and number
of the switch port interface to configure, such as
wlan-gigabitethernet0.
Step 3
switchport protected Configures the interface to be a protected port.
Step 4
end Returns to privileged EXEC mode.
Step 5
show interfaces interface-id
switchport
Verifies your entries.
Step 6
copy running-config startup-config (Optional) Saves your entries in the configuration file.
