Configuring WLAN interfaces
NOTE:
The terms AP and fat AP in this document refer to MSR800, MSR 900, MSR900-E, MSR 930, and
MSR 20-1X routers with IEEE 802.11b/g and MSR series routers installed with a SIC WLAN module.
• Wireless routers support WLAN radio interfaces, which are physical interfaces that provide
wireless network access.
• Wireless routers support WLAN BSS and WLAN Ethernet virtual interfaces. WLAN radio
interfaces on routers can be used as common physical access interfaces. They can be bound to
WLAN BSS interfaces and WLAN Ethernet interfaces.
Hardware compatibility with WLAN
WLAN is not available on the following routers:
• MSR 2600.
• MSR 30-11.
• MSR 30-11E.
• MSR 30-11F.
• MSR3600-51F.

If the WLAN BSS interface does
not exist, this command creates
the WLAN BSS interface first.
When you bind a service with a
WLAN-BSS interface in IMC,
make sure the interface number of
the WLAN BSS interface is no
greater than 31. For more
information about IMC, see H3C
Intelligent Management Center
Getting Started Guide.
3. Set the description string for
the interface.

Configuring WLAN access
The terms AP and fat AP in this document refer to MSR800, MSR 900, MSR900-E, MSR 930, and
MSR 20-1X routers with IEEE 802.11b/g and MSR series routers installed with a SIC WLAN module.
WLAN access overview
A WLAN can provide the following services:
• WLAN client connectivity to conventional 802.3 LANs
• Secured WLAN access with different authentication and encryption methods
• Seamless roaming of WLAN clients in the mobility domain
Terminology
• Client—A handheld computer or laptop with a wireless NIC or a terminal that supports WiFi.
• Access point—An AP bridges frames between wireless and wired networks.
• Fat AP—A fat AP controls and manages all associated wireless stations and bridges frames
between wired and wireless networks.
• Service set identifier—A client scans all networks at first, and then selects a specific SSID to
connect to a specific wireless network.
• Wireless medium—A medium used for transmitting frames between wireless clients. Radio
frequency is used as the wireless medium in the WLAN system.
Client access
A wireless client access process involves three steps: active/passive scanning surrounding wireless
services, authentication, and association, as shown in Figure 1.
Figure 1
Establishing a client access
Scanning
When a wireless client is operating, it usually uses both passive scanning and active scanning to get
information about surrounding wireless networks.
1. Active scanning
10
When a wireless client operates, it periodically searches for (scans) surrounding wireless
networks. During active scanning, the wireless client actively sends probe request frames and
obtains network signals from received probe response frames. Active scanning includes two
modes according to whether a specified SSID is carried in a probe request.
{ A client sends a probe request (with the SSID null, or, the SSID IE length is 0)—The
client periodically sends a probe request frame on each of its supported channels to scan
wireless networks. APs that receive the probe request send a probe response, which
carries the available wireless network information. The client associates with the AP with
the strongest signal. The active scanning mode enables a client to actively get acquainted
with the available wireless services and to access the proper wireless network as needed.
The active scanning process of a wireless client is as shown in Figure 2.
Figure 2
Active scanning (the SSID of the probe request is null or no SSID
information is carried)
{ A client sends a probe request (with a specified SSID)—When the wireless client is
configured to access a specific wireless network or has already successfully accessed a
wireless network, the client periodically sends a probe request carrying the specified SSID
of the configured or connected wireless network. When an AP that can provide the wireless
service with the specified SSID receives the probe request, it sends a probe response. This
active scanning mode enables a client to access a specified wireless network. The active
scanning process is as shown in Figure 3.
Figure 3
Active scanning (the probe request carries the specified SSID AP 1)
2. Passive scanning
Passive scanning is used by clients to discover surrounding wireless networks through listening
to the beacon frames periodically sent by an AP. All APs providing wireless services
periodically send beacons frames, so that wireless clients can periodically listen to beacon
frames on the supported channels to get information about surrounding wireless networks and
connect to an AP. Passive scanning is used by a client when it wants to save battery power.
Typically, VoIP clients adopt the passive scanning mode. The passive scanning process is as
shown in Figure 4.

Authentication
To secure wireless links, the wireless clients must be authenticated before accessing the AP, and
only wireless clients passing the authentication can be associated with the AP. 802.11 links define
two authentication mechanisms: open system authentication and shared key authentication.
For more information about the two authentication mechanisms, see "Configuring WLAN security."
Association
A client that wants to access a wireless network through an AP must be associated with that AP.
Once the client chooses a compatible network with a specified SSID and passes the link
authentication to an AP, it sends an association request frame to the AP. The AP detects the
capability information carried in the association request frame, determines the capability supported
by the wireless client, and sends an association response to the client to notify the client of the
association result. Usually, a client can associate with only one AP at a time, and an association
process is always initiated by the client.
Hardware compatibility with WLAN
WLAN is not available on the following routers:
• MSR 2600.
• MSR 30-11.
• MSR 30-11E.
• MSR 30-11F.
• MSR3600-51F.
Workgroup bridge mode overview
The workgroup bridge mode enables an AP to associate with another AP as a wireless client.
As shown in Figure 5, to provide wirele
ss connectivity for the PCs and printer, you can connect them
to an AP through a hub or a switch and configure the AP as a workgroup bridge. The PCs and printer
access the network through the workgroup bridge.
12
Figure 5 Network diagram
For an AP with two radios, you can configure one radio as a workgroup bridge and configure the
other radio to provide normal access services.
As shown in Figure 6, Rad
io 1 operates as a workgroup bridge, and Radio 2 provides normal access
services. Clients associated with Radio 2 can access the network through the workgroup bridge
Radio 1.
