Description
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.
