Chapter 19 AP Profile
NXC Series User’s Guide
269
Stop
Threshold
This field is available when you enable Band Select.
Select this option and set the threshold number of the connected wireless clients at which the
NXC disables the band select feature.
Balance Ratio This field is available when you enable Band Select.
Select this option and set a ratio of the wireless clients using the 5 GHz band to the wireless
clients using the 2.4 GHz band.
Forwarding Mode Select a forwarding mode for traffic from this SSID.
VLAN ID If you selected the Local Bridge forwarding mode, enter the VLAN ID that will be used to tag all
traffic originating from this SSID if the VLAN is different from the native VLAN. All the station’s
traffic goes through the AP’s gateway.
VLAN
Interface
If you selected the Tunnel forwarding mode, select a VLAN interface. All the station’s traffic is
forwarded to the NXC first.
Controller
offline policy
This field is available only when the forwarding mode is Local Bridge.
When the AP cannot connect to the NXC and Radius Server Type is set to Internal in the
applied security profile, 802.1x authentication will fail. Select this to turn on the controller offline
policy and specify the action the AP takes when the AP controller (the NXC) is not reachable.
Mode This field is available when you enable Controller offline policy.
If you select Standard, the AP hides the SSID when the AP fails to connect to the NXC. The SSID
stays up when the NXC is reachable.
If you select Fallback, the SSID appears only when the NXC is not reachable and is hidden
when the AP can connect to the NXC.
Note: It is highly recommended that you associate this SSID with a security profile
using WPA2-Personal when the mode is set to Fallback. This way wireless clients
can still connect to the SSID without 802.1x authentication when the NXC is not
reachable.
Hidden SSID Select this if you want to “hide” your SSID from wireless clients. This tells any wireless clients in the
vicinity of the AP using this SSID profile not to display its SSID name as a potential connection.
Not all wireless clients respect this flag and display it anyway.
When an SSID is “hidden” and a wireless client cannot see it, the only way you can connect to
the SSID is by manually entering the SSID name in your wireless connection setup screen(s)
(these vary by client, client connectivity software, and operating system).
Enable Intra-BSS
Traffic Blocking
Select this option to prevent crossover traffic from within the same SSID on an AP.
Note: If you associate a layer-2 isolation profile with the SSID, this option will be
selected automatically and cannot be configured.
Enable U-APSD Select this option to enable Automatic Power Save Delivery. This helps increase battery life for
battery-powered wireless clients connected to the AP using this SSID profile.
Enable ARP Proxy The Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a MAC
address. An ARP broadcast is sent to all devices in the same Ethernet network to request the
MAC address of a target IP address.
Select this option to allow the AP to answer ARP requests for an IP address on behalf of a client
associated with this SSID. This can reduce broadcast traffic and improve network performance.
802.11k/v Assisted
Roaming
Select this option to enable IEEE 802.11k/v assisted roaming on the AP.
When the connected clients request 802.11k neighbor lists, the AP will response with a list of
neighbor APs that can be candidates for roaming. When the 802.11v capable clients are using
the 2.4 GHz band, the AP can send 802.11v messages to steer clients to the 5 GHz band.
