• Select a SNMP set in a folder.

The Define SNMP Set page maintains a collection of MIB objects included in a SNMP set.

A SNMP set is a set of MIB objects used to monitor the performance of SNMP enabled network devices. The SNMP protocol is used because an agent cannot be installed on the device. You can assign alarm thresholds to any performance object in a SNMP set. If you apply the SNMP set to a device, you can be notified if the alarm threshold is exceeded. The following methods can be used to configure and assign SNMP sets to machine IDs.

• SNMP quick sets - Creates and assigns a device-specific SNMP set based on the objects discovered on that device during a network scan. SNMP quick sets are the easiest method of implementing SNMP monitoring on a device.
• SNMP standard sets - These are usually generic SNMP sets that are maintained and applied to multiple devices. A quick set, once created, can be maintained as a standard set.
• SNMP individualized sets - This is a standard SNMP set that is applied to an individual device and then customized manually.
• SNMP auto learn - This is a standard SNMP set that is applied to an individual device and then adjusted automatically using auto learn.
• SNMP types - This is a method of assigning standard SNMP sets to devices automatically, based on the SNMP type determined during a network scan.

Typically the following procedure is used to configure and apply SNMP sets to devices.

1. Discover SNMP devices using Discovery > By Network or By Agent.
2. Assign SNMP sets to discovered devices using Monitor > Assign SNMP. This can include quick, standard, individualized or auto learn SNMP sets.
3. Display SNMP alarms using Monitor > SNMP Log or Dashboard List.

The following additional SNMP functions are available and can be used in any order.

• Optionally review the list of all imported SNMP objects using Monitor > Monitor Lists.
• Optionally maintain SNMP sets using Monitor > SNMP Sets.
• Optionally add an SNMP object using Monitor > Add SNMP Object.
• Optionally assign a SNMP type to an SNMP device manually using Monitor > Set SNMP Type.
• Optionally write values to SNMP devices using Monitor > Set SNMP Values.

Note: Certain command line functions from the Net-SNMP suite of applications are used to implement SNMP v1 and SNMP v2c retrieval of information from SNMP capable devices in accordance with all pertinent copyright requirements.

Click the following tabs to define SNMP set details.

• SNMP Sets
• SNMP Icons

SNMP Monitor Set Name

Enter a descriptive name for the SNMP set that helps you identify it in SNMP set lists.

SNMP Monitor Set Description

Describe the SNMP set in more detail. The rationale for the creation of the set is meaningful here; the reason for the creation of the set is sometimes lost over time.

Automatic Deployment to

Selecting a type automatically assigns a newly discovered SNMP device to a Set SNMP Type when performing a network scan function.

Group Alarm Column Name

Assign this SNMP set to a Group Alarm Column Name. If a SNMP set alarm is triggered, the group alarm it belongs to is triggered as well. Group alarms display in the Group Alarm Status pane of the Dashboard List page.

Save

Saves changes to a record.

Save As

Saves a record using a new name.

Export SNMP Set...

Click the Export SNMP Set... link to display the procedure in XML format in the Export Monitor Sets popup window. You can copy it to the clipboard or download it to a text file. SNMP sets can be imported using the SNMP Sets page.
