PAGE 27
Chapter 4: Access Point Configuration General Configuration 4.4.1 General Configuration Access Point Mode Enabled When this 9150 is used only as an 802.IQ base station and not as an access point, this parameter should be disabled to reduce CPU time. Only broadcast and multicast frames will be passed through. Enable ( √ ) this parameter for the 9150 functioning as an access point. The default value is enabled.
PAGE 28
Chapter 4: Access Point Configuration General Configuration For example, the Address Filters Default Action may be to discard all frames destined for addresses not matched in the configuration database. Therefore if the address type field is not matched, the frame will be discarded. But if an address type field is matched in the database, the frame will be forwarded for that address.
PAGE 29
Chapter 4: Access Point Configuration General Configuration 4.4.1.1 Bridge Spanning Tree Algorithm The Spanning Tree Algorithm and its Bridge Protocol work to support and maintain MAC Bridge performance. Important: These parameters are set with optimum default values. Do not adjust these values without discussing the effects with your Psion Teklogix representative.
PAGE 30
Chapter 4: Access Point Configuration General Configuration Bridge Max Age The value of the Maximum Age parameter sent in a Configuration BPDU (Bridge Protocol Data Unit) when the 9150 is the Root or is attempting to become the Root. The Maximum Age is the message age at which a received configuration message is judged “too old” and is discarded.
PAGE 31
Chapter 4: Access Point Configuration Address Filters: MAC Address Root Port Priority The Root Port Priority parameter sets the initial priority value assumed by the Root Port. The default value is 128. Set Port Priority The Set Port Priority parameter sets the prioritization of each enabled port. A lower numerical value for the port priority makes the port more likely to become the designated port. Port Number 1 corresponds to the wired interface; Port Numbers 2 to 7 correspond to WDSLinks 1 to 6.
PAGE 32
Chapter 4: Access Point Configuration Address Filters: MAC Address Name This is any name you wish to use to describe this terminal. Address This parameter provides the corresponding MAC address for the terminal. Address Type This parameter defines whether the source or destination address of the frame should be used to determine the filter action. The destination address has priority over the sources address.
PAGE 33
Chapter 4: Access Point Configuration Protocol Filters 4.4.3 Protocol Filters When the 9150 receives frames, it can forward or discard the messages by filtering the protocol Type fields encapsulated in the frame. The filtering is done on three types of Ethernet headers: Ethernet II, LLC and SNAP. Figure 4.7 on page 84 illustrates the Ethernet header formats. The parameters to configure these filters are described in the sections which follow.
PAGE 34
Chapter 4: Access Point Configuration Protocol Filters If the DSAP and SSAP are both “0xAA”, and the Control field has a value of “0x03”, the LLC header will be followed by an extension which is a SNAP header. The SNAP header includes the Organizational Unit Identifier (OUI) and the protocol type (see “SNAP Filters” on page 88). Figure 4.7 Ethernet Frame Types The listboxes in the Protocol Filters option show the protocol filters already set in the configuration database.
PAGE 35
Chapter 4: Access Point Configuration Protocol Filters Figure 4.8 Protocol Filters Main Menu And Sub-menus New filters can be added by selecting “[#] Create New” in the listbox before entering the “Configure” dialog box. Once a filter is created, the option to delete it can be found on its configuration page (for example, see “Ethernet II Filters” on page 86). When choosing to delete a filter, you will be prompted for confirmation of the deletion, which will give you the opportunity to cancel the action.
PAGE 36
Chapter 4: Access Point Configuration Protocol Filters If a hexadecimal number is entered that is outside the minimum or maximum allowable value for these parameters, you will receive an alert that the Type value is invalid for the specified protocol. 4.4.3.1 Ethernet II Filters Name This is any name you wish to use to describe this Ethernet II filter. Action This parameter can be set to either forward or discard frames with protocol types that match this filter.
PAGE 37
Chapter 4: Access Point Configuration Protocol Filters 4.4.3.2 LLC Filters Name This is any name you wish to use to describe this LLC filter. Action This parameter can be set to either forward or discard frames with protocol types that match this filter. DSAP/SSAP The value entered in the Destination Service/Source Service Access Point (DSAP/SSAP) parameter must be a four-digit hexadecimal number ranging from 0 to 0xFFFF, where the first pair of digits is the DSAP and the last pair is the SSAP.
PAGE 38
Chapter 4: Access Point Configuration Protocol Filters 4.4.3.3 SNAP Filters Name This is any name you wish to use to describe this SNAP (SubNet Access Protocol) filter. Action This parameter can be set to either forward or discard frames with protocol types that match this filter. OUI The value entered in this parameter must be a six-digit hexadecimal number ranging from 0 to 0xFFFFFF, which is the Organization Unique Identifier. When this parameter is enabled ( √ ), the OUI will be filtered.
PAGE 39
Chapter 4: Access Point Configuration Protocol Filters 4.4.3.4 Storm Detection This filter parameter can prevent broadcast/multicast storms from spreading throughout the network. Network storms can burden radio traffic with unnecessary data transmissions. Enabled This parameter enables ( √ ) or disables the Storm Detection filters. Threshold The maximum number of broadcast/multicast frames that should be received in one second is defined in this parameter.

Chapter 4: Access Point Configuration Mobility Configuration 4.5 Mobility Configuration The Mobility Configuration page is entered from the Access Point Configuration menu on the first page. Going to the Mobility Configuration page opens the IAPP Parameters options. The Inter-Access Point Protocol (IAPP) is an extension to the IEEE 802.11b protocol.
PAGE 41
Chapter 4: Access Point Configuration IAPP Parameters In IAPP Announce procedures, when the 9150 is initialized, it sends an IP multicast message to inform the other 9150s in the network that it has become active. It also informs the other 9150s of its continued operation (‘alive’ status) by periodically multicasting the Announce beacon.
PAGE 42
Chapter 4: Access Point Configuration Mobile IP Parameters 4.6 Mobile IP Parameters Mobile IP is used to allow mobile nodes (i.e. terminals) to roam seamlessly between different TCP/IP subnets (10.16.xxx.xxx -> 10.128.xxx.xxx), through foreign and home “agents” (9150s), which act as proxies. When the terminal roams away from its home network, the home agent will take all packets destined for the mobile node, and send them on to the foreign agent, which relays the packets to the “node” (terminal).
PAGE 43
Chapter 4: Access Point Configuration Mobile IP Configuration 4.6.1 Mobile IP Configuration Enable Mobile IP This parameter enables ( √ ) or disables the Mobile IP feature. The default is disabled. 4.6.1.1 Mobile Agent Parameters Advertisement Lifetime This parameter is the maximum length of time (in seconds) that the advertisement is considered valid in the absence of further advertisements.
PAGE 44
Chapter 4: Access Point Configuration Mobile IP Configuration 4.6.1.2 Mobile Node Parameters Registration Lifetime This parameter is the maximum registration lifetime that a terminal will register for, in seconds. This value depends on the dynamics of your system. A few tenths of seconds to a few minutes seem appropriate. The value 65535 is equivalent to “infinite” for the parameter using it.
