Click the Reboot button. end of procedure 22.4 REQUIRING SM AUTHENTICATION Through the use of Prizm Release 2.0 or later, or BAM Release 2.1, you can enhance network security by requiring SMs to authenticate when they register. Three keys and a random number are involved in authentication as follows: • factory-set key in each SM. Neither the subscriber nor the network operator can view or change this key.
Release 8 22.5.2 Operations Guide Protocol and Port Filtering with NAT Disabled Where NAT is disabled, you can filter both protocols and the three user-defined ports. Using the check boxes on the interface, you can either • allow all protocols except those that you wish to block. • block all protocols except those that you wish to allow.
Release 8 Operations Guide The following are example situations in which you can configure protocol filtering where NAT is disabled: • If you block a subscriber from only PPoE and SNMP, then the subscriber retains access to all other protocols and all ports. • If you block PPoE, IPv4, and Uplink Broadcast, and you also check the All others selection, then only Address Resolution Protocol is not filtered.
Release 8 Operations Guide ◦ Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise would have been handled SM to SM, through the Ethernet port of the AP. In the CMMmicro, SM isolation treatment is the result of how you choose to manage the port-based VLAN feature of the embedded switch, where you can switch all traffic from any AP or BH to an uplink port that you specify.
Release 8 Operations Guide 23 MANAGING BANDWIDTH AND AUTHENTICATION This section provides a high-level description of bandwidth and authentication management in a Cyclone network. For more specific information, see Cyclone Bandwidth and Authentication Manager (BAM) User Guide or the Last Mile Gear Cyclone Prizm User Guide. 23.
Release 8 Operations Guide When BAM is enabled in the AP Configuration page, bandwidth management is expanded to apply uniquely specified sustained data rate and burst allocation values to each registered SM. Thus, you can define differently priced tiers of subscriber service. Designing Tiered Subscriber Service Levels Examples of levels of service that vary by bandwidth capability are provided in Table 55 and Table 56.

Release 8 Operations Guide 24 MANAGING THE NETWORK FROM A MANAGEMENT STATION (NMS) SNMPv2 (Simple Network Management Protocol Version 2) can be used to manage and monitor the Cyclone modules under SMI (Structure of Management Information) specifications. SMI specifies management information definitions in ASN.1 (Abstract Syntax Notation One) language. SNMPv2 supports both 32-bit and 64-bit counters. The SMI for SNMPv2 is defined in RFC 1902 at http://www.faqs.org/rfcs/rfc1902.html. 24.
Release 8 Operations Guide To monitor a network element (Cyclone module), SNMPv2 supports • the get command, which instructs the agent to send information about the module to the manager in the NMS. • traversal operations, which the manager uses to identify supported objects and to format information about those objects into relational tables. In a typical Cyclone network, the manager issues these commands to the agents of more than one module (to all SMs in the operator network, for example). 24.1.
Release 8 Operations Guide • • • under dod (6) above: • internet (1) • other branches under internet (1) above: • mgmt (2) • private (4) • other branches under mgmt (2) above: mib-2 (1) and other branches. (See MIB-II below.) under private (4) above: enterprise (1) and other branches. (See Cyclone Enterprise MIB below.) Beneath this level are non-standard branches that the enterprise may define. Thus, the path to an object that is managed under MIB-II begins with the decimal string 1.3.6.1.

Release 8 Operations Guide IMPORTANT! Do not edit these MIB files in ASN.1. These files are intended for manipulation by only the NMS. However, you can view these files through a commercially available MIB viewer. Such viewers are listed under MIB Viewers on Page 411. 5. Download a selected MIB viewer into directory mibviewer. 6. As instructed by the user documentation that supports your NMS, import the eight MIB files that are listed above. end of procedure 24.

Release 8 Operations Guide • Interface 2 represents the RF interface of the module. To monitor the status of Interface 2 is to monitor the traffic on the RF interface. These interfaces can be viewed on the NMS through definitions that are provided in the standard MIB files. 24.9 TRAPS PROVIDED IN THE CYCLONE ENTERPRISE MIB Cyclone modules provide the following SNMP traps for automatic notifications to the NMS: • whispGPSInSync, which signals a transition from not synchronized to synchronized.
Release 8 Operations Guide • dfsChannelChange, which signals that the channel has changed. • dfsImpulsiveInterferenceDetected, which signals that impulsive interference has been detected. 24.12 MIB VIEWERS Any of several commercially available MIB viewers can facilitate management of these objects through SNMP. Some are available as open source software. The Cyclone division does not endorse, support, or discourage the use of any these viewers.
Release 8 Operations Guide 25 USING THE CYCLONE NETWORK UPDATER TOOL (CNUT) The Cyclone Network Updater Tool manages and automates the software and firmware upgrade process for Cyclone radio and CMMmicro modules across the network. This eliminates the need for an administrator to visit each radio in the network (or each AP while using the Autoupdate feature) to upgrade the modules. 25.
Release 8 Operations Guide IMPORTANT! Correct layer information ensures that Network Updater does not command an AP that is behind another AP/SM pair (such as in a remote AP installation) to perform an upgrade at the same time as the SM that is feeding the AP. If this occurs, then the remote AP loses network connection during the upgrade (when the SM in front of the AP completes its upgrade and reboots). 25.

Release 8 Operations Guide 26.8 INTERPRETING DATA IN THE BRIDGING TABLE (ALL) An example of the Bridging Table tab is displayed in Figure 148. Figure 148: Bridging Table tab of AP, example If NAT (network address translation) is not active on the SM, then the Bridging Table tab provides the MAC address of all devices that are attached to registered SMs (identified by LUIDs). The bridging table allows data to be sent to the correct module as follows: ◦ For the AP, the uplink is from RF to Ethernet.
Release 8 Operations Guide 26.9 TRANSLATION TABLE (SM) When Translation Bridging is enabled in the AP, each SM keeps a table mapping MAC addresses of devices attached to the AP to IP addresses, as otherwise the mapping of end-user MAC addresses to IP addresses is lost. (When Translation Bridging is enabled, an AP modifies all uplink traffic originating from registered SM’s such that the source MAC address of every packet will be changed to that of the SM which bridged the packet in the uplink direction.

Frequency This field displays the frequency that the AP or BHM transmits.
Release 8 Operations Guide Jitter, RSSI, and Power Level The AP Evaluation tab shows the received Power Level in dBm and Jitter. Proper alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you should favor lower jitter over higher dBm.
Release 8 Operations Guide TxBER A 1 in this field indicates the AP or BHM is sending Radio BER. EBcast A 1 in this field indicates the AP or BHM is encrypting broadcasst packets. A 0 indicates it is not. Session Count This field displays how many sessions the SM (or BHS) has had with the AP (or BHM). Typically, this is the sum of Reg Count and Re-Reg Count. However, the result of internal calculation may display here as a value that slightly differs from the sum.
Release 8 Operations Guide NumDLHalfSlots This is the number of downlink half slots in this AP or BHM’s frame. To get slots, just divide by 2. NumULContSlots This field displays how many control slots are being used in the uplink portion of the frame. The AP Evaluation tab also provides the following buttons. Rescan APs You can click this button to force the SM or BHS to rescan the frequencies that are selected in the Radio tab of the Configuration page.
