Layer-2 Isolation
Profile
Select a layer-2 isolation profile from the list to associate with this SSID. If none exist, you can use
the Create new Object menu to create one.
Layer-2 isolation allows you to prevent wireless clients associated with your NWA1000 Series
from communicating with other wireless clients, APs, computers or routers in a network.
The disable setting means no layer-2 isolation is used.
QoS Select a Quality of Service (QoS) access category to associate with this SSID. Access categories
minimize the delay of data packets across a wireless network. Certain categories, such as
video or voice, are given a higher priority due to the time sensitive nature of their data packets.
QoS access categories are as follows:
disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged with
access categories.
WMM: Enables automatic tagging of data packets. The NWA1000 Series assigns access
categories to the SSID by examining data as it passes through it and making a best guess effort.
If something looks like video traffic, for instance, it is tagged as such.
WMM_VOICE: All wireless traffic to the SSID is tagged as voice data. This is recommended if an
SSID is used for activities like placing and receiving VoIP phone calls.
WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is recommended for
activities like video conferencing.
WMM_BEST_EFFORT: All wireless traffic to the SSID is tagged as “best effort,” meaning the data
travels the best route it can without displacing higher priority traffic. This is good for activities
that do not require the best bandwidth throughput, such as surfing the Internet.
WMM_BACKGROUND: All wireless traffic to the SSID is tagged as low priority or “background
traffic”, meaning all other access categories take precedence over this one. If traffic from an
SSID does not have strict throughput requirements, then this access category is recommended.
For example, an SSID that only has network printers connected to it.
Rate Limiting
Downlink Define the maximum incoming transmission data rate (either in mbps or kbps) on a perstation
basis.
Uplink Define the maximum outgoing transmission data rate (either in mbps or kbps) on a perstation
basis.
VLAN ID Enter a VLAN ID for the NWA1000 Series to use to tag traffic originating from this SSID.
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 a 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 the NWA1000 Series.
Enable U-APSD Select this option to enable Unscheduled Automatic Power Save Delivery (U-APSD), which is
also known as WMM-Power Save. This helps increase battery life for battery-powered wireless
clients connected to the NWA1000 Series using this SSID profile.
Enable Proxy ARP 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 NWA1000 Series 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.
