CHAPTER 7 REPEATING FEATURES Revised: 1 Oct 13 7-4 EST P/N AA107-195CM determine routing and which paths will be blocked. On a wired Ethernet network, the location of the Root Bridge is not really important, but in a wireless network selection of the Root Bridge is critical to the wireless network routing. Let’s use one of the Example network diagrams from Chapter 3 to continue the discussion (Figure 4). STP Phases The following sections describe the process of the STP in the ESTeem Model 195C/M as how it would happen in the above example. Learning Phase - Once properly configured, each Model 195C/M will begin to search out the other Model 195C/M units in radio range that are programmed in the AP Repeater Peer table. All Model 195C/M’s will calculate their routes to every Model 195C/M in the network based upon the lowest “path length” to the Root Bridge. Path length is the total number of wireless links (repeater peer links) to transmit a packet through the wireless network to the Root Bridge. Note: The Root Bridge in a network should be the Model 195C/M where the majority of the data flow is processed. In every wireless network of two or more radios, the Root Bridge should be user defined. If not defined, the ESTeem 195C/M with the lowest MAC address will be designated as the Root Bridge. In Figure 4, the Plant network (Example 1) is the most logical location for the Root Bridge based upon the amount of data flow. Setting this site as the root bridge is discussed below in Root Bridge. Blocking and Forwarding Phase – To ensure you do not have a network loop situation due to redundant paths in your wireless network, the Model 195C/M will recognize and disable (block) one or more redundant links and provide back up links should the primary link fail. This establishes a wireless mesh network with a series of forwarding links, based upon the shortest path length to the Root Bridge. For example, looking at Figure 4, the Remote Building has two routes to the Root Bridge (Plant Network – Example #1); directly to the site and through the repeater. The direct link between the two sites is the shortest route (lowest Path Length) and will be selected as the primary route unless overridden by manually changing the Path Length in the configuration. Path Length If more than one communication path to the Root Bridge is found, the 195C/M must determine which route to take based upon the lowest Path Length. The default path length to all links in the 195C/M network is 1. If the Path Lengths are equal then the lowest MAC address will determine the priority route. In the ESTeem Mesh Network we want to directly control all data flow so do not want the routes to be automatically determined. Looking again at our Example in Figure 4, if we made no changes to the default path length of 1 (note values in Figure 3) the lowest path cost would be direct from the Remote Building to the Root Bridge (Plant Network). Link Description Total Path Length Direct from Remote Building 1 Remote Build to Root Bridge Through Repeater 2 (Length 1 to repeater + Length 1 to Master = 2) To configure the 195C/M to select the repeater as the primary radio path, set the path length value for the direct link greater than 2 (such as a value of 3) to make this the primary radio path. The lowest path length will identify the highest priority. The Model 195C/M will use this routing, but also switch to direct communication if the repeater were to disappear. Root Bridge In any Access Point Repeater network consisting of more than two sites, one Model 195C/M should be designated as the Root Bridge. Only one Model 195C/M can be designated as the Root Bridge in a given network and should be located where the majority of the Ethernet data flow is processed. This site may be the Master location in a SCADA network or could be configured CHAPTER 7 REPEATING FEATURES Revised: 1 Oct 13 7-5 EST P/N AA107-195CM at a repeater site. Selection is important because all Model 195C/M’s NOT configured as the Root Bridge will choose routing based upon the Path Length to the Root Bridge. If you have any question as to which site in your AP Repeater application should be the Root Bridge, contact ESTeem Customer Support at 509-735-9092 or e-mail your application to [email protected]. The Root Bridge will be selected in one of two ways: the Root Bridge can be manually set (recommended) during the configuration of the Repeater Peer table (Figure 3) or the Root Bridge designation will default to the lowest MAC address of all the Model 195C/M’s in the network. The manual Root Bridge configuration is located in the “Advanced Settings” section. Redundant Backup Figure 4: Redundant Backup Diagram The ESTeem Model 195C/M configured in Access Point Repeater mode will automatically function as a redundant backup if two Model 195C/M’s are installed at the same location (Figure 4). If two Model 195C/M’s are connected to the same switch, one of the Model 195C/M’s will be Blocked when the Spanning Tree Protocol is completed. The network will continue to use this route until any problem with the original Model 195C/M is detected and the second Model 195C/M will begin operation at that site. Redundant Master Configuration The configuration in Figure 4 will also provide a redundant backup for the Master Site (Root Bridge). Configure both Model 195C/M’s as Root Bridges (see above) giving the primary Root Bridge a value of 1 and the secondary Root Bridge a value of 2. CHAPTER 8 ANTENNA SETUPS Revised: 1 Oct 13 8-1 EST P/N AA107-195CM ESTeem offers different types of antennas ranging from ¼ wave to 5/8 wave in physical size. The user choice is dependent on the application. Communications in the VHF and UHF bands are normally over "Line of Sight (LOS)". Looking from the antenna of one wireless modem you must be able to see the antenna of the wireless modem you wish to communicate with. If a large object obstructs the line of sight view it is unlikely that satisfactory communications…
