PHN-5337 002V000 – DECEMBER 2021 PAGE 2 OF 21 1 Introduction This User Guide provides details of the operation and usage of the SNMP Configuration Mode of the Cambium Networks PTP 670 Wireless Ethernet Bridge. This Guide consists of: • Description: A general description of the SNMP Configuration Mode. • Transactional model: Details of the procedure to enter or exit the configuration mode, to validate a proposed configuration and to commit configuration changes. Use this description of the transactional model to create effective management applications in SNMP managers using the configuration mode. • Validation and relevance: A guide to the rules that are applied by the ODU when a proposed configuration is submitted, together with information about the selection of attributes that are relevant in any particular configuration. Use this information to understand and create valid configurations. The SNMP Configuration Mode is supported from System Release 03-40. This User Guide is updated for System Release 03-60. 2 Description The SNMP Configuration Mode allows an operator to modify the wireless and quality of service (QoS) configuration of a PTP 670 outdoor unit (ODU) using the SNMP management interface. The SNMP interface is the normal choice for integrating PTP 670 with a Network Management System (NMS) or for automating batch processing of configuration changes to multiple ODUs. Note The web-based (HTTP or HTTPS) management interface provides an interactive user experience, optimized for a human operator rather than integration with an NMS. Refer to the PTP 670 User Guide for details of the web interface. The essential steps in using the SNMP Configuration Mode are as follows: • Enable the SNMP Configuration Mode • Update the attribute values to create the proposed configuration • Apply the validate action • Check the validation status • If the proposed configuration is valid, commit the changes, or commit and reboot, otherwise modify the proposed configuration and re-validate • If the commit is successful, the ODU exits the SNMP Configuration Mode automatically. The context-sensitive validation rules applied by the PTP 670 are identical to those used in the web interface. The validation prevents the PTP 670 from being configured with an incorrect or unsupported configuration. The commit action applies all of the changes made in the Configuration Mode in a single transaction. Refer to the PTP 670 User Guide for general information about the planning, installation, configuration and operation of PTP 670. PHN-5337 002V000 – DECEMBER 2021 PAGE 3 OF 21 3 Transactional model The SNMP Configuration Mode is managed using the following SNMP objects: Table 1 SNMP Configuration Mode control objects Attribute Access Description sNMPConfigurationMode read-write disabled(0) | enabled(1) Set to enabled(1) to enter the configuration mode. The system resets to disabled(0) when changes have been committed. Set to disabled(0) to exit the configuration mode without committing changes. sNMPValidateConfiguration read-write disabled(0) | enabled(1) Set to enabled(1) to validate the configuration. The system resets to disabled(0). sNMPValidationStatus read-only Indicates the result of the validation notStarted(0) | inProgress(1) | noErrorPleaseCommit(2) noErrorPleaseCommitandReboot (3) | error(4) sNMPCommitConfiguration read-write idle(0) | commit(1) | commitandReboot(2) Set to commit(1) to commit changes. Set to commitandReboot(2) to commit changes and restart the ODU. The system resets to idle(0). sNMPCommitStatus read-only Indicates the status of the current commit action notStarted(0) | inProgress(1) | successful(2) | failedConfigurationwasnotvalidated(3) | failedConfigurationisvalidbutCommitandRebootwasrequired(4) sNMPValidationErrorAttribute read-only Text string containing the name of the attribute associated with the first validation error detected. sNMPValidationErrorInstance read-only Instance number of the attribute associated with the first validation error detected. sNMPValidationErrorReason read-only Text string containing a description of the first validation error detected. The necessary steps in making configuration changes using the Configuration Mode are shown in Figure 1. To abandon changes at any point without committing, SET SNMP Configuration Mode = Disabled. Note Attributes accessed using SNMP Configuration Mode can only be changed using the configuration mode; any attempt to change these attributes using SNMP will be rejected if the configuration mode is disabled. Read-write attributes that are not accessed using SNMP Configuration Mode can only be changed when SNMP Configuration Mode is disabled. PHN-5337 002V000 – DECEMBER 2021 PAGE 4 OF 21 Note Attribute values that have been changed using SET messages while SNMP Configuration Mode is Enabled will not be apparent in a GET response for that attribute until after changes have been committed. Figure 1 Flow chart for SNMP Configuration Mode SNMP Configuration Mode Wait for another SNMP user to relinquish configuration mode Enabled Disabled SET SNMP Configuration Mode = Enabled SNMP Configuration Mode Wait for web-user to log out Disabled Enabled Change the configuration to avoid the validation error SET configuration attributes SET SNMP Validate Configuration = Enabled No Error. Please Commit. SNMP Validation Status Error No Error. Please Commit and Reboot. SET SNMP Commit Configuration = Commit SET SNMP Commit Configuration = Commit and Reboot GET SNMP Validation Error Attribute GET SNMP Validation Error Instance GET SNMP Validation Error Reason PHN-5337 002V000 – DECEMBER 2021 PAGE 5 OF 21 Interaction with web-based management PTP 670 ODUs do not allow the SNMP Configuration Mode to be enabled at the same time that a user is logged in to the web-based management interface. SNMP Configuration Mode has a privilege greater than the System Administrator role in the web-based interface, but lower than the Security Officer role. Enabling SNMP Configuration Mode will automatically log out any web user except for a web user with the Security Officer role. If a Security Officer user is logged in at the web-based interface, an attempt to set sNMPConfigurationMode will be rejected. When Identity-Based User Accounts is Disabled, the single role-based user has the same privileges as the Security Officer role. 4 Validation and relevance The sections below contain a series of directed graphs and associated notes specifying the rules for validity and relevance of configuration attributes that can be set using SNMP Configuration Mode. Validity is determined for an individual attribute by checking the requested value against a range of permitted values. In general, the range of permitted values for individual attributes is specified in the SNMP MIB. Validity is also determined across a group of related attributes by checking combinations of attribute values. For example, two or more attributes might be individually valid, but the value of one attribute might be inconsistent with the selected values of the remaining attributes; in this case the overall configuration is invalid. Attributes are determined to be “relevant” if their value affects the operation of the ODU. If an attribute is not included in a particular path through the directed graphs below then the attribute is not relevant, its value is not checked for validity and the attribute value is not saved when configuration is committed using the SNMP Configuration Mode. For example, a change to iPv6Address is applied if iPVersion is set to iPv6, but ignored if iPVersion is set to iPv4. Notation The notation used is as follows: • The direction of the graphs indicates precedent and dependent attributes. For each attribute, the direction is left to right. • • Attribute names are in bold typeface. A selection is indicated by a grey rectangle, where the attribute name is in bold typeface at the top of the rectangle, and attribute value choices are shown in blue normal typeface. • A physical property of the ODU that cannot be changed by management action is indicated by a grey rectangle, where the property name is in normal typeface, and the possible values are in blue normal typeface. • If a choice is allowed by the SNMP MIB, but not shown in a selection, then that choice is not valid at the point in the graph. • Some precedent attributes appear in multiple graphs. In this case, assume the same selection each time the attribute occurs. • The graphical representation does not specify all of the rules that define validity, and in some places additional rules are added in a table below the associated graphs. A requested configuration is valid if it corresponds to a route through each of the graphs below, and complies with the additional validation rules provided below the associated graph. All attributes included in the route through the graph are relevant.
