Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual
Rev Version 2.14
WPA Enterprise - Supplicant
(Client) Configuration
Figure 30 WPA Enterprise Supplicant
Username /
Password
User credentials that match a valid user on the RADIUS server.
Enable Debug
Disabled for normal operation. Enables debug mode for use during commissioning.
To be used only if requested by ELPRO technical support.
Trusted CA
certificate upload
Upload the certificate of the issuer of the RADIUS server’s certificate. This enables
the Supplicant to verify the identity of the RADIUS server during the authentication
process. Supported EAP method is PEAP / MSCHAPv2.
Certificate
Verification result
Once a certificate has been loaded, this field will contain validation information for
the certificate. If this field is blank or contains errors, the certificate is invalid.
Trusted CA

Displays the contents of the loaded certificate.
3.7 Normal Operation
After addresses are configured the units are ready for operation. Refer to “1.0 Network Topology” for an explanation
on the operation of a bridge and router.
Bridge Operation (Transparent Network)
A bridge connects several Ethernet networks together, and makes them appear as a single Ethernet network to
higher protocol layers. By default, the 945U-E is configured as a transparent bridge. When a transparent bridge
is started, it learns the location of other devices by monitoring the source address of all incoming traffic. Initially
it forwards all traffic between the wired Ethernet port and the wireless port. However, by keeping a list of devices
heard on each port the transparent bridge can decide which traffic must be forwarded between ports and will only
transfer a message from the wired port to the wireless port if it is required.
A bridge will forward all broadcast traffic between the wired and wireless ports. If the wired network is busy with
broadcast traffic, the radio network on the 945U-E can be unnecessarily overburdened. Use filtering to reduce
broadcast traffic sent over the radio. Refer to “3.18 Filtering” for information on how to configure a filter.
By default, a transparent bridge does not handle loops within the network. There must be a single path to each
device on the network. Loops in the network will cause the same data to be continually passed around that loop.
Redundant wireless links may be set up by enabling the bridge Spanning Tree Protocol (see “3.5 Spanning Tree
Algorithm” for details).
