SNMP Attributes (Interfaces or Scalars)
This panel appears if you are creating an SNMP monitor. The application stores not absolute
numbers from counters but the counter’s change since its last measurement.
Figure 32-21. SNMP Attribute Management
Columns include the SNMP Attribute Name, OID, Syntax, and Meta Syntax.
NOTE:
If you check the Collect from ifXTable checkbox, then OpenManage Network Manager attempts to fetch
attributes from the ifXTable. These attributes are ifHighSpeed, ifHCInOctets, ifHCInUcastPkts,
ifHCOutOctets and ifHCOutUcastPkts. If any of these attributes are not available, then it fetches from
ifTable.
Clicking the buttons to the right opens either an editor at the bottom of the screen, or a MIB
browser where you can retrieve these attributes. See the following sections for details.
•MIB Browser
• Add / Edit SNMP Attributes
CAUTION:
If you receive the following message: Device fault: Return packet too big. in the Monitor Status Summary,
then you have selected too many SNMP attributes to poll in a single request. Please modify your monitor
to request smaller numbers of attributes
