SNMP Quick Sets

Monitor > Assign SNMP > SNMP Info link

The SNMP Info link page displays a list of SNMP objects provided by the specific SNMP device you selected. These objects are discovered by performing a limited SNMP "walk" on all discovered SNMP devices each time a LAN Watch is performed. You can subsequently define device-specific SNMP sets called quick sets and associate alerts with these quick sets. Quick sets can be individualized for a single device. The standard version of the quick set can be shared with other administrators and applied to similar devices throughout the VSA. The prefix (QS) is used to distinguish quick set names from other kinds of SNMP sets.

  1. Discover SNMP devices using Monitor > LAN Watch.
  2. Assign SNMP sets to discovered devices using Monitor > Assign SNMP.
  3. Click the SNMP info link in the Assign SNMP page to display a list SNMP objects that apply to the specific SNMP device you selected.
  4. Display SNMP alarms using Monitor > SNMP Log or Dashboard List.

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

Discovered Objects Sets tab

The Discovered Object Sets 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".

SNMP Sets tab

The SNMP Sets 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 - Select the MIB object. Click Add Object to add a MIB object that currently does not exist on the Monitor Lists page.
  • Current SNMP Value - The value returned by the object/instance combination by the latest SNMP "walk".
  • 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.
  • 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.
  • 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.
  • 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.
