Chapter 1: Configuration Configuring radio parameters Dedicated Multicast Virtual Circuit (VC) A Multicast VC allows to configure multicast packets to be transmitted over a dedicated channel at a configurable rate of 1X, 2X, 4X or 8X. This feature is available only for the PMP 450 and PMP 450i and is not backward compatible with PMP 430 series of radios. To configure Multicast VC, the AP must have this enabled. This can be enabled in the “Multicast Data Control” section (under Configuration > Radio page).

Chapter 1: Configuration Configuring radio parameters DFS for 5 GHz Radios Dynamic Frequency Selection (DFS) is a requirement in several countries and regions for 5 GHz unlicensed systems to detect radar systems and avoid co-channel operation.
Chapter 1: Configuration Configuring radio parameters Contention slots Contention slots are symbols at the end of the uplink subframe that are reserved for random access (network entry and bandwidth requests) and cannot be used for data transmission. These symbols form the contention space. The frame is 2.5 ms or 5 ms long, and it is divided into a downlink subframe (data transmitted from the AP to the SM) and an uplink subframe (data transmitted from the SM to the AP).
Chapter 1: Configuration Configuring radio parameters Table 69 Throughput penalty per modulation Modulation mode Throughput penalty for each additional contention slot 2.5 ms frame 5 ms frame QPSK SISO (1X) 204 kbps 102 kbps QPSK MIMO (2X) 409 kbps 204 kbps 16-QAM MIMO (4X) 819 kbps 409 kbps 64-QAM MIMO (6X) 1.22 Mbps 614 kbps 256-QAM MIMO (8X) 1.63 Mbps 819 kbps Table 69 shows that the throughput penalty for each additional contention slot increases with modulation mode.
Chapter 1: Configuration Configuring radio parameters Type of traffic in a sector Besides the number of SMs, the other main factor in contention slots selection is the type of traffic. If the sector experiences a lot of uplink traffic composed of small packets, for example in a sector that serves several VoIP streams, the average number of bandwidth requests transmitted by each SM is high.
Chapter 1: Configuration Configuring radio parameters Cluster of APs It is recommended to use care when changing the contention slots configuration of only some APs in a cluster, because changes affect the effective downlink/uplink ratio and can cause co-location issues. In a typical cluster, each AP should be configured with the same number of contention slots to assure proper timing in the send and receive cycles.
Chapter 1: Configuration 6. Configuring radio parameters Input the configuration parameters for this AP (same duty cycle and max distance as the other APs, different contention slots) 7. Click “Calculate” 8. Note the following values from the results: AP Antenna Transmit End: ____________________ AP Antenna Receive Start: ____________________ 9. Check that the two following equations are both true: AP1 Receive Start > AP2 Transmit End AP2 Receive Start > AP1 Transmit End 10.
Chapter 1: Configuration Configuring radio parameters To avoid this interference scenario, the duty cycle of AP2 can be further adjusted slightly. For example, changing the duty cycle of AP2 from 80% to 79% changes the AP2 Antenna Transmit End and Antenna Receive start times as follows: • AP2 Antenna Transmit End = 1.7168 ms • AP2 Antenna Receive Start = 1.8700 ms The two equations have to be checked again for co-location: • AP1 Antenna Receive Start > AP2 Transmit End 1.7243 ms >1.

Chapter 1: Configuration Configuring radio parameters Through hardware and software enhancements, the PPS performance of the PMP 450i Series AP and PMP 450b SM has been improved to 40k packets/second, measured through a standard RFC2544 test using 64 bytes packets. With this enhancement, operators are able to provide higher bandwidth including better VoIP and video services to end customers using existing SM deployments. PMP 450m is capable of supporting more than 100k PPS (packets per second).
Chapter 1: Configuration Setting up SNMP agent Setting up SNMP agent Operators may use SNMP commands to set configuration parameters and retrieve data from the AP and SM modules. Also, if enabled, when an event occurs, the SNMP agent on the 450 Platform Family sends a trap to whatever SNMP trap receivers configured in the management network.

Chapter 1: Configuration Configuring syslog Configuring syslog 450 Platform Family includes: • Syslog event logging • Configuring system logging Syslog event logging Following events are logged in syslog as explained in Table 76. Table 76 Syslog parameters Attribute Meaning Timestamp All syslog messages captured from the radio have a timestamp. Configuration This includes any device setting that has changed and includes the old or Changes new parameter value, including the device reboots.
Chapter 1: Configuration Configuring syslog Syslog page of AP/BHM The Syslog Configuration page for AP/BHM is shown in Table 77. Table 77 Syslog Configuration attributes - AP Attribute Syslog DNS Server Usage Meaning To configure the AP/BHM to append or not append the DNS server name to the syslog server name. Syslog Server The dotted decimal or DNS name of the syslog server address. Syslog Server Port The syslog server port (default 514) to which syslog messaging is sent.
Chapter 1: Configuration Configuring syslog Table 78 Syslog Configuration attributes - SM Attribute Meaning Syslog Configuration This control determines whether the SM will attempt to use the syslog server Source definition from the AP, or whether it will use a local server definition. When set to AP preferred, use local when AP configuration unavailable, and if the SM can register with an AP, then it uses the syslog server defined on that AP.
Chapter 1: Configuration Configuring syslog This provides a selection for the minimum syslog message severity that is sent to the syslog server. Values range from fatal (highest severity and least Syslog Minimum Level verbose) to info (lowest severity, maximum verbosity). For example: If the Syslog Minimum Level is set to notice, then only messages with severity notice and above are sent. Syslog page of BHS The Syslog Configuration page is shown in Table 79.
Chapter 1: Configuration Configuring syslog control whether it sends syslog messages. This allows an operator to override the BHM settings for individual BHSs in a sector. This control determines whether the BHS attempts to use the minimum syslog level defined by the BHM, or whether it uses a local defined value using the Syslog Minimum Level parameter.
Chapter 1: Configuration Configuring remote access Configuring remote access Accessing SM/BHS over-the-air by Web Proxy The SM/BHS may be accessed via the AP/BHM management GUI by navigating to Home > Session Status (or Home > Remote Subscribers for AP only) and clicking on the SM’s hyperlink. For example, to access one of the SMs, click LUID: 002 – [0a-00-3e-37-b9-fd], as shown in Figure 30. Figure 30 AP Session Status page The SessionStatus.
Chapter 1: Configuration Monitoring the Link Monitoring the Link Link monitoring procedure After configuring the link, either an operator in the network office or the SM/BHS INSTALLER user in the field (if read access to the AP/BHM is available to the INSTALLER) must perform the following procedure. Who is authorized and able to do this depends on local operator password policy, management VLAN setup and operational practices.
Chapter 1: Configuration 5 Monitoring the Link Click Session Count tab of Session Status List to display values for Session Count, Reg Count, and Re-Reg Count. • Session Count: This field displays how many sessions the SM/BHS has had with the AP/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.
Chapter 1: Configuration Monitoring the Link Exporting Session Status page of AP/BHM The SessionStatus.xml hyper link allows user to export all displayed SMs or BHS data in Session Status table into an xml file. Figure 33 Exporting Session Status page of PMP 450m AP In case of PMP, if the session status page does not list any SM, the SessionStatus.xml will still be visible but the file would be empty. The file will contain data from all of the 5 different tables.
Chapter 1: Configuration Configuring quality of service Configuring quality of service Maximum Information Rate (MIR) Parameters Point-to-multipoint links use the following MIR parameters for bandwidth management: • Sustained Uplink Data Rate (kbps) • Uplink Burst Allocation (kb) • Sustained Downlink Data Rate (kbps) • Downlink Burst Allocation (kb) • Max Burst Downlink Data Rate (kbps) • Max Burst Uplink Data Rate (kbps) Set each of these parameters per AP or per SM independently.
Chapter 1: Configuration Configuring quality of service MIR Data Entry Checking Uplink and downlink MIR is enforced as shown in Figure 34. Note In these figures, entry refers to the setting in the data rate parameter, not the burst allocation parameter.
Chapter 1: Configuration Configuring quality of service Note CIR settings only apply to the Legacy scheduler. Starting in release 16.1 a new Proportional scheduler can optionally be enabled via Configuration -> Quality of Service -> Scheduler setting. If Proportional Scheduler is set, CIR's are not used.
Chapter 1: Configuration Configuring quality of service Figure 36 SM Prioritization on SM The feature does not take effect, however, until SM Prioritization is enabled on the AP, because the scheduler runs on the AP. Prioritization Allocation percentages per group are configured on the AP to determine how many timeslot resources are dedicated to each priority group.
Chapter 1: Configuration Configuring quality of service SM Prioritization with CIR When the SM Prioritization feature is used with CIR, Cambium’s scheduler will first prioritize scheduling of data channels configured with a CIR, but only within the limits of that SMs Prioritization Group allocation. In the example configuration shown in Figure 37, there are 6 SMs in the Low Prioritization group.
Chapter 1: Configuration Configuring quality of service Weighted Fair Queuing (WFQ) Note This feature is not supported on PMP 450m. This feature lets the user assign a percentage of air interface resources to each of the Data Channel levels. The WFQ apply both to the DL and the UL. Note that there is no BC/MC traffic in the UL direction. One of the benefits of WFQ is that the configuration can be accomplished at the AP rather than at each individual SMs.
Chapter 1: Configuration Configuring quality of service For example, if, during peak traffic hours, the Ultra High, High, and Low priority Data channels were experiencing heavy traffic loads, but the medium priority aggregate traffic load was light and only used 10% of the scheduling slots in a particular direction, the remaining unused 12% of the slots would be allocated first to the Ultra High priority traffic in queue.
Chapter 1: Configuration Configuring quality of service WFQ with SM Prioritization Note This feature is not supported on PMP 450m. Figure 39 shows a WFQ configuration with the SM Prioritization feature also enabled. Figure 39 WFQ with SM Prioritization In the example shown in Figure 39, 2 of the 8 SMs have been configured for the High Priority Group. The other 6 are in the Low Priority group. 45% of air interface timeslot resources have been allocated to the Low priority group.
Chapter 1: Configuration Configuring quality of service Proportional Scheduler This feature, also known as the Rate Plan feature, allows a user to set Plans per SM in units of Kbps. The proportional scheduler maintains the proportions of the SMs’ plans when the sector is congested. A default plan setting per direction also exists on the AP and is used in case an SM is not configured with a Plan (for example, the SM is not upgraded to system release 16.1 yet).
Chapter 1: Configuration Configuring quality of service The number of data channels available on the AP is still limited to 238 in release 15.2 This could be 238 SM’s each configured with a single Low Priority channel, or, for example, 59 SMs with 4 data channels configured and 1 SM with 2 data channels configured. A module prioritizes traffic by: • reading the 802.1p field of the 802.1Q header in a received packet, where VLAN is enabled on the module.
Chapter 1: Configuration Configuring quality of service Traffic Scheduling The characteristics of traffic scheduling in a sector are summarized in Table 80. Table 80 Characteristics of traffic scheduling Category Factor Throughput Latency Treatment Aggregate throughput, less additional overhead 132 Mbps for 20 MHz Higher for 30 MHz or 40 MHz and lower for smaller bandwidths.
Chapter 1: Configuration Configuring quality of service Setting the Configuration Source The AP includes a Configuration Source parameter, which sets where SMs that register to the AP are controlled for MIR, CIR, VLAN, and the high-priority channel as follows.

Chapter 1: Configuration Attribute Configuring quality of service Meaning Sustained Downlink Specify the rate at which the AP is replenished with credits (tokens) for Data Rate transmission to each of the SMs in its sector. This default imposes no restriction on the uplink.
Chapter 1: Configuration Configuring quality of service • Configuration Source on page 1-73 Max Burst Downlink These parameters allow operators to specify the data rate at which an SM is Data Rate allowed to transmit (until burst allocation limit is reached) before being recharged at the Sustained Downlink Data Rate with credits to transit more. When set to 0 (default), the burst rate is unlimited.
Chapter 1: Configuration Configuring quality of service Low: Management data uses low priority VC. High: Management data uses highest priority VC SM Prioritization Low This parameter displays the number and percentage of SMs allocated with Group Count low prioritization. SM Prioritization High This parameter displays the number and percentage of SMs allocated with Group Count high prioritization.
Chapter 1: Configuration Configuring quality of service Data Channel This parameter allows to configure the percentage of frame space allocated Allocation - for broadcast/multicast. Broadcast/Multicast Data Channel This parameter allows to configure the percentage of frame space allocated Allocation - Low for low priority QoS level. Priority Data Channel This parameter allows to configure the percentage of frame space allocated Allocation - Medium for medium priority QoS level.

Chapter 1: Configuration Configuring quality of service Sustained Uplink Data Specify the rate that this SM is replenished with credits for transmission. This Rate default imposes no restriction on the uplink.
Chapter 1: Configuration Configuring quality of service • 2: Select 2 to enable Low and High Priority channels. • 3: Select 3 to enable Low, Medium, and High Priority channels. • 4: Select 4 to enable all channels. For each enabled channel, configure the respective Downlink CIR and Uplink CIR. Low Priority Channel This parameter shows whether low priority data channel is enabled or not. Its value is derived based on the number of data channels selected. This parameter is enabled by default.
Chapter 1: Configuration Configuring quality of service Note: CIR values are not applicable for proportional scheduler. High Priority Uplink This field indicates the minimum rate at which high priority traffic is sent CIR over the uplink (unless CIR is oversubscribed or RF link quality is degraded). • Committed Information Rate (CIR) on page 1-237 • Setting the Configuration Source on page 1-246 Note: CIR values are not applicable for proportional scheduler.
Chapter 1: Configuration Threshold Modulation Configuring quality of service Using Threshold Modulation, if one SM’s modulation degrades, then all other SMs’ throughputs are affected as long as the degraded modulation is above the threshold. Once the modulation goes below the threshold, the reaources are no longer increased for that SM, effectively capping the effect to other SMs. Priority Precedence Allows operator to decide if 802.
Chapter 1: Configuration Prioritize TCP ACK Configuring quality of service To reduce the likelihood of TCP acknowledgement packets being dropped, set this parameter to Enabled. This can improve throughput that the end user perceives during transient periods of congestion on the link that is carrying acknowledgements. This parameter, when enabled, can be particularly useful when running bi-direction FTP sessions over the link.
Chapter 1: Configuration Installation Color Code Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. While the SM is accessible for configuration from above the AP (for remote provisioning) and below the SM (for local site provisioning), no user data is passed over the radio link.
Chapter 1: Configuration Zero Touch Configuration Using DHCP Option 66 Zero Touch Configuration Using DHCP Option 66 This feature allows an SM to get its configuration via DHCP option 66. This can be used for the initial configuration of an SM as well as managing the configuration of SMs on an ongoing basis. Here is how it works in brief: • When the SM boots up, if it is set to use DHCP client, it will send out a DHCP Discover packet which includes a request for DHCP Option 66.
Chapter 1: Configuration Zero Touch Configuration Using DHCP Option 66 Creating a Golden config file The easiest way to create the golden config file is to configure an SM, export its configuration and edit it. To export the configuration file from the GUI of the SM, go to “Configuration > Unit Settings” tab, go to the “Download Configuration File” section and click on the “.cfg” link. This will give you a text file in JSON format.
Chapter 1: Configuration Zero Touch Configuration Using DHCP Option 66 { “colorCode”: 42, “priority”: 1 } ] }, “networkConfig”: { “lanDhcpState”: 1 } }, “cfgFileVersion”: “1.0”, “cfgFileString”: “Canopy configuration file”, “configFileParameters”: { “rebootIfRequired”: true } } When configuration is imported, only the items that exist in the configuration file are modified. Parameters that are not in the imported file are not changed.
Chapter 1: Configuration 2 Zero Touch Configuration Using DHCP Option 66 If you have multiple “Scopes” defined, identify the correct “Scope” that will serve IP addresses for the SMs 3 Right click on “Scope Option” under the correct “Scope” and select “Configure Options” Page 1-265
Chapter 1: Configuration 4 Zero Touch Configuration Using DHCP Option 66 In the “Scope Options” dialog, scroll down to “066 Boot Server Host Name”, select the checkbox and enter the full URL to the golden config file as the “String value”. Then click “OK”. 5 In the DHCP snap-in window, right click and “Refresh” to see the DHCP option 66 in the list of DHCP options Supported URL Formats FTP, TFTP, HTTP and HTTPS URLs are supported. Some examples are given below. • ftp://10.120.163.253/canopy.
Chapter 1: Configuration Zero Touch Configuration Using DHCP Option 66 In this case, the SM will append “.cfg” to the path and try to get that file. For example, if the SM’s MAC address is 0a-00-3e-a2-c2-74, it will request for ftp://10.120.163.253/smconfig/0a003ea2c274.cfg. This mechanism can be used to serve individual config file for each SM. Troubleshooting 1 Ensure that the___14 SM is running 13.3 or newer version of software.
Chapter 1: Configuration Configuring Radio via config file Configuring Radio via config file The 450 Platform Family supports export and import of a configuration file from the AP or SM as a text file. The configuration file is in JSON format. To export or import the configuration file, the logged in user needs to be an ADMINISTRATOR and it must not be a “read-only” account. The exported configuration file contains the complete configuration including all the default values.
Chapter 1: Configuration 2 Configuring Radio via config file Click on “Browse” button under “Upload and Apply Configuration File” tab and select the configuration file from disk. 3 Click “Upload” followed by “Apply Configuration File” button click. 4 The “Status of Configuration File” section will show the results of the upload. 5 Review it to make sure there are no errors.

Chapter 1: Configuration Configuring a RADIUS server Configuring a RADIUS server Configuring a RADIUS server in a PMP 450 Platform network is optional, but can provide added security, increase ease of network management and provide usage-based billing data. Understanding RADIUS for PMP 450 Platform Family PMP 450 Platform modules include support for the RADIUS (Remote Authentication Dial In User Service) protocol supporting Authentication and Accounting.
Chapter 1: Configuration Configuring a RADIUS server Note Aradial 5.3 has a bug that prevents “remote device login”, so doesn’t support the user name and password management feature. Choosing Authentication Mode and Configuring for Authentication Servers - AP On the AP’s Configuration > Security tab, select the RADIUS AAA Authentication Mode. The following describes the other Authentication Mode options for reference, and then the RADIUS AAA option. • Disabled: Requires no authentication.
Chapter 1: Configuration Configuring a RADIUS server Table 89 Security tab attributes Page 1-277
Chapter 1: Configuration Configuring a RADIUS server Attribute Meaning Authentication Mode Operators may use this field to select the following authentication modes: Disabled—the AP requires no SMs to authenticate. Authentication Server —the AP requires any SM that attempts registration to be authenticated in Wireless Manager before registration. AP PreShared Key - The AP acts as the authentication server to its SMs and will make use of a user-configurable pre-shared authentication key.
Chapter 1: Configuration Selection Key Configuring a RADIUS server This option allows operators to choose which authentication key is used: Use Key above means that the key specified in Authentication Key is used for authentication Use Default Key means that a default key (based off of the SM’s MAC address) is used for authentication Encryption Key Specify the type of airlink security to apply to this AP. The encryption setting must match the encryption setting of the SMs.
Chapter 1: Configuration Configuring a RADIUS server • SNMPv2c and SNMPv3 – It enables both the protocols. Telnet This option allows to Enable and Disable Telnet access to the Radio. FTP This option allows to Enable and Disable FTP access to the Radio. TFTP This option allows to Enable and Disable TFTP access to the Radio. NTP server This option allows to Enable and Disable NTP server access to the Radio.
Chapter 1: Configuration Configuring a RADIUS server Note Having SMs to use RADIUS by enabling Enforce Authentication avoids the security issue of SMs possibly registering to “rogue” APs, which have authentication disabled.
Chapter 1: Configuration Attribute Configuring a RADIUS server Meaning The authentication key is a 32-character hexadecimal string used when Authentication Key Authentication Mode is set to AP PreShared Key. By default, this key is set to 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.
Chapter 1: Configuration Configuring a RADIUS server If Realms are being used, select Enable Realm and configure an outer identity in the Identity field and a Realm in the Realm field. These must match the Phase 1/Outer Identity and Realm configured in the RADIUS server. The default Identity is “anonymous”. The Identity can be up to 128 non-special (no diacritical markings) alphanumeric characters. The default Identity/Realm Realm is “canopy.net”.
Chapter 1: Configuration Configuring a RADIUS server Web, Telnet, FTP Enter the expiry in seconds for remote management sessions via HTTP, Session Timeout telnet or ftp access to the AP. If you want to prevent any device that is connected to the Ethernet port of the SM from accessing the management interface of the SM, select Ethernet Access Disabled. This selection disables access through this port to via HTTP (the GUI), SNMP, telnet, FTP, and TFTP.
Chapter 1: Configuration TFTP Configuring a RADIUS server This option allows to Enable and Disable TFTP access to the Radio. SM - Phase 1 (Outside Identity) parameters and settings The protocols supported for the Phase 1 (Outside Identity) phase of authentication are eapttls (Extensible Authentication Protocol Tunneled Transport Layer Security) and eapMSChapV2 (Extensible Authentication Protocol – Microsoft Challenge-Handshake Authentication Protocol). Configure an outer Identity in the Username field.
Chapter 1: Configuration Configuring a RADIUS server When a certificate is in use, after the SM successfully registers to an AP, an indication of In Use will appear in the description block of the certificate being used. The public certificates installed on the SMs are used with the private certificate on the RADIUS server to provide a public/private key encryption system. Note Root certificates of more than one level (Example - a certificate from someone who received their CA from Verisign) fails.
Chapter 1: Configuration • Configuring a RADIUS server If Enable Realm is selected on the SM’s Configuration > Security tab, then the same Realm appears there (or access to it). • The same Phase 2 (Inner Identity) protocol as configured on the SM’s Configuration > Security tab under Phase 2 options. • The username and password for each SM configured on each SM’s Configuration > Security tab.
Chapter 1: Configuration Configuring a RADIUS server Assigning SM management IP addressing via RADIUS Operators may use a RADIUS AAA server to assign management IP addressing to SM modules (framed IP address). SMs now interpret attributes Framed-IP-Address, Framed-IP-Netmask, and CambiumCanopy-Gateway from RADIUS. The RADIUS dictionary file has been updated to include the CambiumCanopy-Gateway attribute and is available on the Cambium Software Support website.
Chapter 1: Configuration Configuring a RADIUS server Note Beginning with System Release 12.0.2, two RADIUS dictionary files are available on the Cambium website – “RADIUS Dictionary file – Cambium” and “RADIUS Dictionary file – Motorola”. In addition to a renaming of attributes, the Cambium-branded dictionary file contains two new VSAs for controlling uplink and downlink Maximum Burst Data Rate (these VSAs are listed below in Table 91).
