SNMP Quick Sets

Monitor > Assign SNMP > SNMP Info link

The SNMP Info link page displays a list of MIB objects provided by the specific SNMP device you selected. These MIB objects are discovered by performing a limited SNMP "walk" on all discovered SNMP devices each time a LAN Watch is performed. You can use the list of discover MIB objects to instantly create a device-specific SNMP set—called a quick set—and apply it to the device. Once created, quick sets are the same as any standard set. They display in your private folder in Monitor > SNMP Sets and in the drop-down list in Monitor > Assign SNMP. A (QS)prefix reminds you how the quick set was created. Like any other standard set, quick sets can be individualized for a single device, used with Auto Learn, shared with other users, and applied to similar devices throughout the VSA.

  1. Discover SNMP devices using Monitor > LAN Watch.
  2. Assign SNMP sets to discovered devices using Monitor > Assign SNMP.
  3. Click the hyperlink underneath the name of the device, called the SNMP info link, in the Assign SNMP page to display a dialog.
    • Click Discovered MIB Objects and select one or more of the MIB objects that were discovered on the SNMP device you just selected.
    • Click Quick Set Items and, if necessary, edit the alarm thresholds for selected MIB objects.
    • Enter a name after the (QS) prefix in the header of the dialog.
    • Click the Apply button to apply the quickset to the device.
  4. Display SNMP monitoring data returned by the quick set using Monitor > SNMP Log, the same as you would for any other standard SNMP set.
  5. Optionally maintain your new quick set using Monitor > SNMP Sets.

Use the following tabs on the SNMP Info link page to configure an SNMP quick set.

Discovered MIB Objects tab

The Discovered MIB Objects tab lists all objects sets discovered by the last SNMP "walk" that apply to the selected SNMP device. You can use this tab to add objects and instances to an SNMP quick set for this device.

  • Add Instance - Click to add this instance of this object to an SNMP "quick set" displays in the SNMP Set tab of this same window.
  • Add All Instances - Click to add all instances of this object to an SNMP "quick set" displays in the SNMP Set tab of this same window.
  • SNMP Object - The name of the SNMP object. If no name is provided for the object, the OID numerical designation displays.
  • Instance - The instance of the object. Many objects have multiple instances, each of which have a different value. For example, the different instances could be ports on a router, or paper trays on a printer. The field is blank if the last number of an OID is zero, which indicates there can only be one member of this object. If an instance is not blank, or any number other than 0, than more than one "instance" of this same object exists for the device. You can specify monitoring of multiple instances of an object by entering a range of numbers, such as 1-5,6 or 1,3,7. You can also enter All.
  • Current SNMP Value - The value returned by the object/instance combination by the latest SNMP "walk".

Quick Set Items tab

The Quick Set Items tab configures the objects and instances selected to be included in your SNMP quick set. Click the edit icon to define SNMP monitoring attributes for the selected objects. You can also use the Add button to add a new object and set these same attributes.

  • SNMP Object - The SNMP object name or OID number.
  • SNMP Instance - The last number of an object ID may be expressed as a table of values instead of as a single value. If the instance is a single value, enter 0. If the instance is a table of values, enter a range of numbers, such as 1-5,6 or 1,3,7. You can also enter All.
  • Alarm Operator - For character string return values, the options are Changed, Equal or NotEqual. For numeric return values, the options are Equal, NotEqual, Over, or Under.
  • Alarm Threshold - Set a fixed value that the returned value is compared to, using the selected Alarm Operator, to determine when an alarm is triggered.
  • Value Returned as - If the MIB object returns a numeric value, you can choose to return this value as a Total or a Rate Per Second.
  • Current SNMP Value - The value returned by the object/instance combination by the latest SNMP "walk".
  • SNMP Sets tab

SNMP Icons tab

  • Customize the alarm icons for this specific SNMP quick set. See SNMP Icons for a general explanation of how to use this page.
