Wireless Local Area Networks (WLANs)
Configuring a WLAN
For increased security, you can prevent two wireless stations in a particular
WLAN from communicating with each other. You have three options for
controlling wireless station-to-station traffic in a particular WLAN:
■ allow all inter-station traffic
When a wireless station attempts to communicate with another station in
the WLAN, the Wireless Edge Services xl Module forwards the packet
toward the second station’s RP.
■ drop all inter-station traffic
When a wireless station attempts to communicate with another station in
the WLAN, the Wireless Edge Services xl Module drops the packet.
■ forward inter-station traffic through the switch
This option allows inter-station traffic but ensures that it complies with
your network policies. When a wireless station attempts to communicate
with another station in the WLAN, the Wireless Edge Services xl Module
forwards the traffic into the wired network in the VLAN configured for
that WLAN (or in the user’s dynamic VLAN). The wireless services-
enabled switch enforces any applicable access controls and sends the
packet back to the module to be forwarded to toward the second
station’s RP.
To enable inter-station blocking on a WLAN, complete these steps:
1. Access the Edit screen for the WLAN:
a. Select Network Setup > WLAN Setup and click the Configuration tab.
b. Select the WLAN and click the Edit button. The Edit screen is displayed.
2. In the Inter-station Traffic drop-down menu under Advanced, choose how
the module treats inter-station traffic:
• Drop packets
• Allow Packets
• Forward through switch
The default setting is to allow inter-station traffic.
