Simultaneous access point and WDS support
The V-M200 can be configured to simultaneously support wireless communities and one or 
more WDS links. Although this offers flexibility, it does have the following limitations:
The total available bandwidth on the radio is shared between all WDS links and wireless 
users. This can result in reduced throughput if lots of traffic is being sent by both wireless 
users and the WDS links. You can use the QoS feature to prioritize...

Key concepts
8-4
Traffic on a WDS link is assigned to a queue based on the selected priority mechanism. Traffic 
delivery is based on strict priority (per the WMM standard). Therefore, if excessive traffic is 
present on queues 1 or 2, it will reduce the flow of traffic on queues 3 and 4. 
Regardless of the priority mechanism that is selected, traffic that cannot be classified by a 
priority mechanism is assigned to queue 3.
NoteWhen traffic is forwarded onto a WDS link from a wireless...

Diffserv (Differentiated Services)
This mechanism classifies traffic based on the value of the Differentiated Services (DS) 
codepoint field in IPv4 and IPv6 packet headers (as defined in RFC2474). The codepoint is 
composed of the six most significant bits of the DS field. 
Spanning-tree protocol
The Spanning-Tree Protocol (STP) can be used to prevent undesirable loops from occurring 
in the network that may result in decreased throughput. To enable STP for wireless...

WDS configuration settings
To view or add a WDS link, select Wireless > WDS. 
To configure a WDS link, select its name in the list. Or to add a WDS link, select Add WDS 
Link. In either case, the WDS link page opens. 
Settings 
Enabled/Disabled
Specify if the WDS link is enabled or disabled. Once a link is enabled, it actively attempts to 
establish the WDS connection to the remote V-M200. To view the status of the WDS 
connection, select Status > WDS.

Name
Name of the WDS link.
Speed
Sets the speed the link will operate at. For load balancing you may want to limit the speed of 
a link when connecting to multiple destinations. 
Select the Auto option to have the V-M200 automatically choose the speed that provides the 
best throughput (least number of errors).
Security
AES/CCMP security
Enables AES with CCMP encryption to secure traffic on the link. The V-M200 uses the key 
you specify in the Key field to...

D.Test the link and make performance adjustments
The WDS link should now be active. 
1.Select To o l s  >  P i n g on V-M200 #1 and ping the address of V-M200 #2 (192.168.5.20). If the 
ping succeeds, it means that the WDS link is working.
2.Select Status > WDS. The WDS status page...
