DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide Figure 3-6 Basic Setup SSID - Edit window The fields that can be configured or displayed are described below: Parameter Description SSID Hide SSID Deny Broadcast VLAN MAC Authentication Redirect Redirect URL Wireless ARP Suppression Mode L2 Distributed Tunneling Mode Enter Service Set Identifier (SSID) of the network, which is an alphanumeric key that uniquely identifies a wireless local area network. Tick the check box to hide the SSID broadcast to discourage stations from automatically discovering the access point. Tick the check box to prohibit the AP from responding to client probe requests Enter a VLAN ID. Click Local or RADIUS to enable MAC Authentication. The MAC address of the client must be configured at the local switch or the external RADIUS server. Select the HTTP radio button to redirect wireless clients to a custom Web page. Enter the URL where all initial HTTP accesses should be redirected to. This text box is accessible only when HTTP is selected as the redirect type. Use the drop-down menu to enable or disable the APs to reduce the number of broadcasted ARP requests on the wireless interfaces. Reducing broadcasts helps conserve power on the wireless clients. The wireless clients that use power-save mode must wake up and use more power when they detect broadcast frames. NOTE: Enabling this feature slightly degrades AP packet forwarding performance due to extra packet filtering to find DHCP packets and extra processing for ARP request and reply packets. Networks that do not use IPv4 should not enable this feature. The distributed L2 tunneling mode supports L3 roaming for wireless clients without forwarding any data traffic to the Unified Switch. Use the drop-down menu to enable or disable the mode. L2 tunneling is recommended when the Unified Switch does not support hardware forwarding acceleration or hardware-based L2 tunnels. NOTE: 1. When there is only one switch managing all APs and that switch goes down, all APs shut down their radios and the tunnel is terminated. After the switch recovers and the AP becomes managed again, the client that was previously tunneling traffic will re-associate and obtain an IP address on the network where its currently located. This IP address will be different from the IP address it was using when it was tunneling, and the traffic will not be tunneled. 395

Figure 3-6 Basic Setup SSID – Edit window

The fields that can be configured or displayed are described below:

Parameter

Description

SSID

Enter Service Set Identifier (SSID) of the network, which is an alphanumeric key

that uniquely identifies a wireless local area network.

Hide SSID

Tick the check box to hide the SSID broadcast to discourage stations from

automatically discovering the access point.

Deny Broadcast

Tick the check box to prohibit the AP from responding to client probe requests

VLAN

Enter a VLAN ID.

MAC Authentication

Click

Local

RADIUS

to enable MAC Authentication. The MAC address of the

client must be configured at the local switch or the external RADIUS server.

Redirect

Select the

HTTP

radio button to redirect wireless clients to a custom Web page.

Redirect URL

Enter the URL where all initial HTTP accesses should be redirected to. This text

box is accessible only when HTTP is selected as the redirect type.

Wireless ARP

Suppression Mode

Use the drop-down menu to enable or disable the APs to reduce the number of

broadcasted ARP requests on the wireless interfaces. Reducing broadcasts helps

conserve power on the wireless clients. The wireless clients that use power-save

mode must wake up and use more power when they detect broadcast frames.

NOTE:

Enabling this feature slightly degrades AP packet forwarding performance

due to extra packet filtering to find DHCP packets and extra processing for

ARP request and reply packets. Networks that do not use IPv4 should not

enable this feature.

L2 Distributed

Tunneling Mode

The distributed L2 tunneling mode supports L3 roaming for wireless clients without

forwarding any data traffic to the Unified Switch. Use the drop-down menu to

enable or disable the mode. L2 tunneling is recommended when the Unified Switch

does not support hardware forwarding acceleration or hardware-based L2 tunnels.

NOTE:

When there is only one switch managing all APs and that switch goes

down, all APs shut down their radios and the tunnel is terminated. After

the switch recovers and the AP becomes managed again, the client that

was previously tunneling traffic will re-associate and obtain an IP

address on the network where its currently located. This IP address will

be different from the IP address it was using when it was tunneling, and

the traffic will not be tunneled.
