AT-WL2411 Installation and User’s Guide An ARP request is a multicast packet, which means the packet is sent to all devices on the network. If the access point is acting as an ARP server, it translates the multicast packet into a unicast packet, which means that the packet is only sent to the destination end device. Thus, all wireless end devices do not need to wake up to listen to the ARP request, which saves battery life. To configure the access point as an ARP server: 1.
AT-WL2411 Installation and User’s Guide Configuring the Access Point to Send ARP Requests ARP requests are multicast packets, which means they are sent to all devices on the network. The access point periodically sends an unsolicited ARP request to the default IP router so that all routers can update their routing tables. This ARP request enables a network management program to learn about the access point on the network by querying routers.

AT-WL2411 Installation and User’s Guide The root priority can be a value from 0 to 7. If you set the root priority to 0, the access point can never become the root access point. You should always set a WAPs root priority to 0. For more information, see “About the Root Access Point” later in this section. IAPP Frame Type Controls the encapsulation of Inner Access Point Protocol (IAPP) frames sent by this access point. You can select either DIX (Ethernet 2.0) or SNAP encapsulation.
AT-WL2411 Installation and User’s Guide For more information, see “About Secondary LANs and Designated Bridges” later in this section. Secondary LAN Flooding When an access point is the designated bridge in a secondary LAN, this parameter specifies the types of frames it passes from the primary LAN to the secondary LAN. Disabled No flooding occurs unless the root access point (in the Global Flooding screen) enables the Multicast or Unicast Outbound to Secondary LANs parameter.
AT-WL2411 Installation and User’s Guide attached to the network. Each hello message contains the LAN ID of the access point that originated the message. The protocol does not allow wireless links to exist between access points that do not have matching LAN IDs. About Bridging Wireless end devices operate similarly to other Ethernet products; therefore, all of your existing Ethernet applications will work with the wireless network without any special networking software.
AT-WL2411 Installation and User’s Guide If you enable bridging on a remote subnet, a single access point functions as the designated bridge for the secondary LAN. In this case, only the designated bridge can establish an IP tunnel. Any other access point on the remote subnet must attach to the network through the designated bridge. End device MAC/IP addresses are fully visible on the remote subnet.
AT-WL2411 Installation and User’s Guide wireless end devices roam. The database also includes the power management status of each end device, which allows the access point to support the pending message feature of the network. The forwarding database allows the bridging software to make efficient forwarding decisions. Switch Support Ethernet switches that do not comply with the 802.1D standard have difficulty handling wireless end devices that roam between different switched segments.
AT-WL2411 Installation and User’s Guide The access point that is responsible for bridging data between the secondary LAN and the primary LAN is called the designated bridge. In both types of secondary LANs, the designated bridge acts the same. The designated bridge must be an access point that has at least one radio set to Station mode or is the endpoint of an IP tunnel.
AT-WL2411 Installation and User’s Guide Configuring Global Parameters Global parameters are configured on the root access point and on any other access point that is a root candidate (does not have a root priority of 0). The root access point sends these settings to all other access points on the network. You should set the same global parameters for the root access point and its backup candidates.

Syntax fd Use the fd command to ensure that the correct version of the file is in the active boot segment. Typing fd ab: shows only the files loaded in the active boot segment.
fe Purpose Erases the files in a particular segment. To recover the files after they have been erased, you must reload them from another source. Syntax fe segment where segment is the name or number of the segment to be erased. Example To erase the contents of segment 1, enter: fe 1 You can enter ALL instead of a segment name or number if you want to erase segments 1 through 4. Fe ib: erases the contents of the inactive boot segment. Note You must execute the fe command before you execute a TFTP transfer.
AT-WL2411 Wireless Access Point Installation Guide Using Sdvars Commands Use sdvars commands in Console Command mode to manipulate certain software download variables. Sdvars commands support both GET and SET arguments. You can enter sdvars commands to GET a software download object, and then issue the sdvars command using the SET argument to assign the object a specified value. The sdvars commands are described in this section using the SET argument.
sdvars set starttime Purpose Sets the internal variable starttime. Starttime is a countdown time such that when zero is reached, the software download process begins. You set this variable to reflect how long into the future the access point is to begin downloading and executing the script file from the TFTP server. When the timer reaches 0, the access point uses the values in serveripaddress and scriptfilename to get the script file that is to be executed.
AT-WL2411 Wireless Access Point Installation Guide Example Consider the following script file commands: sdvars set fe ab sdvars set TFTP get * sdvars set reboot checkpoint 1 checkpoint 2 access point.prg ab checkpoint 3 When the software download is started, you can use SNMP to query its progress by reading the checkpoint variable. If the variable has a value of 2, you know that the access point is trying to execute the TFTP get statement.
where: none does not change the active segments. The default is none. Also, when the reboot is completed, the access point resets this value to none. boot changes the inactive boot segment to the active boot segment. data changes the inactive data segment to the active data segment. both changes both the boot and data inactive segments to the active segments.
AT-WL2411 Wireless Access Point Installation Guide Using TFTP Commands TFTP commands are file transfer commands that you execute when you are in Console Command mode. A access point can act as either a client or server in the TFTP environment. As a server, the access point can service read and write requests from a access point client. As a client, the access point can read files from and write files to any TFTP server on the network. Both the client and server must operate in octet, or 8-bit, mode.
local filename is the name you wish to call the file on the access point. The name must include a segment number or name followed by a colon. An actual filename is optional. If only the segment name is supplied, the filename is set equal to the filename that is embedded in the file header on the server. Example The following command gets file access point.DNL from a directory on a PC server with IP address 1.2.3.4 and stores it in the inactive boot segment on the access point. tftp get 1.2.3.
AT-WL2411 Wireless Access Point Installation Guide tftp put Purpose Copies a file from a client to the server or to another access point. Syntax tftp put IP address foreign filename local filename where: IP address is the IP address of the server. You can use an asterisk (*) here if you want to use the value in the serveripaddress. foreign filename is the name of the file as it will appear on the server.
tftp server log Purpose Your access point can function as a TFTP server. You can use the TFTP server log command to save a history of TFTP client requests. Syntax tftp server log The TFTP server log contains useful TFTP server status information. The log begins when you set up the server. You must reboot the access point to clear the log. tftp server start Purpose A access point can obtain files from a TFTP server.
AT-WL2411 Wireless Access Point Installation Guide The following table lists error messages that can be issued from the TFTP server. These messages are sent to the client and are meant to be read from the client perspective. Error Message Explanation TFTP server only supports octet mode The client is attempting to transfer a file in ASCII mode. The access point TFTP server only supports octet mode, which includes binary and image.

Glossary ARP (Address Resolution Protocol) The protocol used by TCP/IP networks to relate IP addresses with the physical network addresses of network interfaces. BFSK (Binary Frequency Shift Key) A broadcasting method that lengthens the range but halves the throughput as compared to the QFSK method. bridge A device that expands a local area network by forwarding frames between data link layers associated with two separate physical media types, usually carrying a common protocol.
AT-WL2411 Wireless Access Point Installation Guide data link tunneling An access point encapsulates an Ethernet frame in a data frame and forwards the frame to the next access point on the path to the final destination. Data link tunneling is used to make mobility transparent to the underlying network or to isolate the radio traffic from terminals on an Ethernet segment. Data link tunneling occurs automatically when Ethernet bridging is disabled on the root access point.
flooding A frame is flooded when the destination location is unknown. The destination location of a multicast frame is never known. Unicast and multicast flooding parameters determine how a flooded frame is forwarded. home IP subnet The IP subnet that contains the wired primary LAN and any wireless extensions of the subnet. IGMP (Internet Group Management Protocol) IGMP is a protocol that allows the access point to have more than eight IP tunnels.
AT-WL2411 Wireless Access Point Installation Guide multicast address A form of broadcast address through which copies of the frame are delivered to a subset of all possible destinations that have a common multicast address. non-bridging secondary LAN A secondary LAN that does not have a designated bridge. A nonbridging secondary LAN is used to connect access points without using wireless hops. outbound frames Frames moving away from the primary LAN.
remote IP subnet A secondary LAN attached to the network through an IP tunnel. root The access point with the highest root priority becomes the root of the network spanning tree. If the root becomes inactive, the remaining root candidates negotiate to determine which access point becomes the new root. The root can be used to set system-wide flooding and RF parameters. The root is also the only node in the network that can originate IP tunnels.
AT-WL2411 Wireless Access Point Installation Guide SNMP (Simple Network Management Protocol) SNMP is a popular network management protocol in the TCP/IP and SPX/IPX protocol suite. SNMP allows TCP/IP and SPX/IPX sites to exchange configuration and status information. It uses management programs called "agents" to monitor network traffic. SNMP stores the information it collects in the Management Information Base (MIB).
WEP Wired Equivalent Privacy, a feature that can be enabled in the IEEE 802.11b HR radio that allows data encryption for wireless communications. wireless bridging A wireless link that connects two wired Ethernet segments. Two access points can be used to provide a point-to-point or wireless bridge between two buildings, so that wired and wireless devices in each building can communicate with devices in the other building.
