NOTE
When operating bridging in the 802.11n 2.4 GHz band, set the Channel
Bandwidth to 20 MHz, rather than the default 20/40 MHz. In the 2.4 GHz
20/40 MHz band, the operating bandwidth can change from 40 MHz to 20 MHz if any
20 MHz WAP devices are detected in the area. The mismatched channel bandwidth can
cause the link to disconnect.
See
Radio
(Basic Settings) for information on configuring these settings.
•
When using WDS, be sure to configure WDS on both WAP devices participating in the
WDS link.
•
You can have only one WDS link between any pair of WAP devices. That is, a remote
MAC address may appear only once on the WDS page for a particular WAP device.
To configure a WDS bridge:
STEP 1
Select Wireless > WDS Bridge in the navigation pane.
STEP 2
Select Enable for Spanning Tree Mode. When enabled, STP helps prevent switching loops.
STP is recommended if you configure WDS links. Select Radio 1 or Radio 2 for each WDS
link that you configure.
STEP 3
Select Enable for WDS Interface.
STEP 4
Configure the remaining parameters:
•
Remote MAC Address—Specifies the MAC address of the destination WAP device;
that is, the WAP device on the other end of the WDS link to which data is sent or
handed-off and from which data is received.
TIP
You can find the MAC address on the Status and Statistics > Network Interface page.
•
Encryption—The type of encryption to use on the WDS link; it does not have to match
the VAP you are bridging. The WDS Encryption settings are unique to the WDS bridge.
The options are none, WEP, and WPA Personal. The WPA2-PSK is an option for the
WDS link encryption and VAP security. The administrator needs to choose those
options to enforce them.
If you are unconcerned about security issues on the WDS link, you may decide not to
set any type of encryption. Alternatively, if you have security concerns you can choose
between Static WEP and WPA Personal. In WPA Personal mode, the WAP device uses
WPA2-PSK with CCMP (AES) encryption over the WDS link. See WEP on WDS
Links or WPA/PSK on WDS Links following this procedure for more information about
encryption options.
NOTE
Static WEP is applicable only when the radio is operating in legacy mode: 802.11a for 5 GHz
radio and 802.11b/g for 2.4 GHz radio.
