Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual
So, in this example,Site B has a total of three IP addresses: 192.168.5.3 for the default interface; 169.254.0.3 for the WDS link to Site A; and
169.254.5.3 for the WDS link to Site C.Note: We choose to always use the same host address of 3 for unit B on all of its interfaces regardless of
the network address.
• The first routing rule specifies 192.168.0.0 as the destination address (the network address of Site A) – because the last byte is zero, this
refers to a route to the network (192.168.0.1 – 192.168.0.254 as opposed to a route to an individual host IP).The same rule specifies the
address 169.254.0.2 as the gateway address (this is the WDS Router IP address that Site A has been configured with for its WDS link to Site
B). So,this routing rule effectively tells the BU-245U-E that any traffic destined for the network 192.168.0.X should be forwarded to Site A via
WDS link address 169.254.0.2.
• The second routing rule will be similar except the Destinations IP address will be 192.168.6.0 with a Netmask of 255.255.255.0, indicating all
traffic for the 192.168.6.X network will be routed through the WDS link address 169.254.5.4.This is the WDS Router IP address that Site C
has been configured with for its WDS link to Site B).
Units A and C would also require similar pairs of routing rules to direct traffic to the network addresses at the end points of their respective WDS
links. Refer to section 3.14 “Routing Rules”for further information on routing rules.
The WDS Configuration page (as seen above) is accessible from the “Repeaters”link on any of the configuration web pages. The configurable
WDS parameters are summarized below.
Add Entry Button Add an entry to the WDS Connections table. This adds a virtual station to the device.
Delete Entry Button Delete the currently selected entry in the WDS Connections table. To select a row,click anywhere in the
row with the mouse, to highlight the entire row.
WDS Connections:
Connection Mode Specify the connection mode for this link.AP (Downlink) configures the connection as a virtual access point.
Sta (Uplink) configures the connection as a virtual client. Point-to-point configures the connection as a fixed link.
SSID / MAC Address AP Mode: Specify the SSID that this virtual access point will use. Stations connecting to this virtual access
point use this SSID.
Sta Mode: Specify the SSID that this virtual station will use when connecting to other access points.
Point-to-Point Mode: Specify the MAC address of an Access Point to establish a Fixed link with.Usually only
required for third-party devices.
Encryption Select the required Encryption (if any) for this WDS link.
Encryption Key Enter the Encryption key (for WEP encryption) or the passphrase (for WPA encryption).For WEP encryption, the
encryption key is set as WEP Key 1. For Sta Mode,this must match WEP Key 1 on the Access point this virtual
client will connect to. For AP mode,clients must configure their WEP Key 1 to the same value as this key and
select the Default WEP Key to be WEP Key 1.
Router IP Leave this field blank if this WDS interface is to be bridged with the default wireless interface. Otherwise enter
the IP address for this connection that specifies the IP network to which messages are routed.
Router Subnet Leave this field blank if this WDS interface is to be bridged with the default wireless interface.
Otherwise enter the subnet mask of the network to which messages are routed.
STP Applicable to WDS bridged connections only. Select the STP option if you wish to enable the bridge
Spanning Tree Protocol on this connection.
