All transmit and receive statistics shown are totals since the client association started.A TSPEC is a traffic specification that is sent from a QoS-capable wireless client to an AP requesting a certain amount of network access for the traffic stream (TS) it represents. A traffic stream is a collection of data packets identified by the wireless client as belonging to a particular user priority. An example of a voice traffic stream is a Wi-Fi CERTIFIED telephone handset that marks its codec-generated data packets as voice priority traffic. An example of a video traffic stream is a video player application on a wireless laptop that prioritizes a video conference feed from a corporate server.

If a packet exceeds the fragmentation threshold you set, the fragmentation function is activated and the packet is sent as multiple 802.11 frames.If the packet being transmitted is equal to or less than the threshold, fragmentation is not used.
:LUHOHVV6HWWLQJVRadioCisco Small Business WAP121 and WAP321 Wireless-N Access Point with PoE 40REVIEW DRAFT Version 2—CISCO CONFIDENTIALSetting the threshold to the largest value (2,346 bytes) effectively disables fragmentation. Fragmentation plays no role when Aggregation is enabled.Fragmentation involves more overhead both because of the extra work of dividing up and reassembling of frames it requires, and because it increases message traffic on the network. However, fragmentation can help improve network performance and reliability if properly configured.Sending smaller frames (by using lower fragmentation threshold) might help with some interference problems; for example, with microwave ovens.By default, fragmentation is off. We recommend not using fragmentation unless you suspect radio interference. The additional headers applied to each fragment increase the overhead on the network and can greatly reduce throughput.•5767KUHVKROG—The Request to Send (RTS) Threshold value, from 0 to 2347.The RTS threshold indicates the number of octets in an MPDU, below which an RTS/CTS handshake is not performed. Changing the RTS threshold can help control traffic flow through the AP, especially one with a lot of clients. If you specify a low threshold value, RTS packets will be sent more frequently. This will consume more bandwidth and reduce the throughput of the packet. On the other hand, sending more RTS packets can help the network recover from interference or collisions which might occur on a busy network, or on a network experiencing electromagnetic interference.•0D[LPXP$VVRFLDWHG&OLHQWV—The maximum number of stations allowed to access this AP at any one time.You can enter a value between 0 and 200.•7UDQVPLW3RZHU—A percentage value for the transmit power level for this AP.The default value, which is 100%, can be more cost-efficient than a lower percentage since it gives the AP a maximum broadcast range and reduces the number of APs needed.To increase capacity of the network, place APs closer together and reduce the value of the transmit power. This helps reduce overlap and interference among APs. A lower transmit power setting can also keep your network more secure because weaker wireless signals are less likely to propagate outside of the physical location of your network.

It functions as a simple OSI layer 2 network device.In the point-to-multipoint bridge mode, one AP acts as the common link between multiple APs. In this mode, the central AP accepts client associations and communicates with the clients and other repeaters. All other APs associate only with the central AP that forwards the packets to the appropriate wireless bridge for routing purposes.The AP can also act as a repeater. In this mode, the AP serves as a connection between two APs that might be too far apart to be within cell range. When acting as a repeater, the AP does not have a wired connection to the LAN and repeats signals by using the wireless connection. No special configuration is required for the AP to function as a repeater, and there are no repeater mode settings.

It relieves both the wireless client users and the AP administrators from having to know network names, keys, and various other cryptographic configuration options. WPS facilitates network setup by allowing the administrator to use a push button or PIN mechanism to establish wireless networks, thereby avoiding the manual entry of network names (SSIDs) and wireless security parameters:•3XVKEXWWRQ: The WPS button is either on the product or a clickable button on the user interface.•3HUVRQDO,GHQWLILFDWLRQ1XPEHU3,1: The PIN either is located on a product label or can be viewed on product user interface.WPS maintains network security during these simple steps by requiring both the users of new client devices and WLAN administrators to either have physical access to their respective devices or secure remote access to these devices.8VDJH6FHQDULRVTypical scenarios for using WPS include the following:•A user wishes to enroll a client station on a WPS-enabled WLAN. (The enrolling client device may detect the network, and prompt the user to enroll, although this is not necessary.) The user triggers the enrollment by pushing a button on the device. The AP's administrator then pushes a button on the AP. During a brief exchange of WPS protocol messages, the AP supplies the new client with a new security configuration via the Extensible Authentication Protocol (EAP). The two devices disassociate, and then reassociate and authenticate with the new settings.•A user wishes to enroll a client station on a WPS-enabled WLAN by supplying the AP administrator with the PIN of the client device. The administrator enters this PIN on the UI of the AP and triggers the device enrollment. The new enrollee and the AP exchange WPS messages, including a new security configuration, disassociate, reassociate, and authenticate.•An AP administrator purchases a new AP that has been certified by the Wi-Fi Alliance to be compliant with WPS version 2.0, and wishes to add the AP to an existing (wired or wireless) network. The administrator turns on the AP, and then accesses a network host that supports the WPS registration protocol. The administrator enters the AP device’s pin on the UI of this

(On a wired LAN, the WPS protocol messages are transported via the Universal Plug and Play, or UPnP, protocol.) The host registers the AP as a new network device and configures the AP with new security settings.•An AP administrator has just added a new AP to an existing (wireless or wired) network via WPS, and wishes to grant network access to a new client device. The device is enrolled through either the "PIN" or "push button control (PBC)" methods described above, but this time the device enrolls with the external registrar, with the AP acting solely as a proxy. •A wireless device that does not support WPS must join the WPS-enabled WLAN. The administrator, who cannot use WPS in this case, instead manually configures the device with the SSID, public shared key, and cryptography modes of the WPS-enabled AP. The device joins the network.The PIN is either an eight-digit number that uses its last digit as a checksum value, or a four-digit number with no checksum. Each of these numbers may contain leading zeroes.:365ROHVThe WPS standard assigns specific roles to the various components in its architecture: •(QUROOHH—A device that can join the wireless network.•$3—A device that provides wireless access to the network.•5HJLVWUDU—An entity that issues security credentials to enrollees and configures APs.

If WPA2-PSK encryption mode is enabled, then an valid pre-shared key (PSK) must be configured and CCMP (AES) encryption must be enabled.•The VAP is operationally enabled.WPS is operationally disabled on the VAP if any of these conditions are not met. 127( Disabling WPS on a VAP does not cause disassociation of any clients previously authenticated via WPS on that VAP([WHUQDODQG,QWHUQDO5HJLVWUDWLRQIt is not necessary for the WAP121 itself to handle the registration of clients on the network. The AP can either use its internal registrar, or act as a proxy for an external registrar. The external registrar may be accessed either via the wired or wireless LAN. An external registrar may also configure the SSID, encryption mode, and public shared key of a WPS-enabled BSS. This capability is very useful for "out-of-box" deployments; that is, when an administrator simply attaches a new AP to a LAN for the first time. If the AP is using an internal registrar, it enrolls new clients using the configuration of the VAP associated with the WPS service, whether this configuration was configured directly on the AP or acquired by an external registrar through WPS.&OLHQW(QUROOPHQWPush-button ControlThe AP enrolls 802.11 clients via WPS by one of two methods: the push-button control (PBC) method, or the personal identification number (PIN) method. Using the PBC method, when the user of a prospective client pushes a button on the enrolling device, the administrator of the AP with an enabled internal registrar pushes a similar (hardware or software) button. This sequence begins enrollment process, and the client device joins the network. Although the WAP121 does not support an actual hardware button, it allows the administrator to initiate the enrollment for a particular VAP using a “software button” in the web-based AP configuration utility. 127( There is no defined order in which the buttons on the client device and AP must be pressed. Either device can initiate the enrollment. However, if the software button on the AP is pressed, and no client attempts to enroll after 120 seconds, the AP terminates the pending WPS enrollment transaction.
