Interface Configuration Attributes
You set the value for a set of model type interface configuration attributes in the Interface Configuration grouping. Some of the attributes available include the following:
  •  
    Admin Status
    This attribute sets the administrative status for an interface.
  •  
    Create Sub-Interfaces
    Set this attribute to Yes, and if a device supports RFC1573, 
    DX NetOps Spectrum
     will model the device’s sub-interfaces.
  •  
    Interface Name Primary Suffix
    DX NetOps Spectrum
     uses the value of this required attribute to name interfaces for the model or models for the Rename Interface Models action. Choose from a set of available suffixes in the drop-down list when editing this attribute.
  •  
    Interface Name Secondary Suffix
    DX NetOps Spectrum
     uses the value of this optional secondary attribute to name interfaces for the model or models for the Rename Interface Models action. It is prefixed by an underscore (_) and follows the value of the primary suffix. This secondary attribute is optional.
Stale Interfaces
 
DX NetOps Spectrum
 handles interface definitions that are temporarily removed from their corresponding MIB tables using its Stale Interface functionality. These types of situations can include:
  • A module is temporarily removed from a device
  • A configured tunnel temporarily goes down on a device
In these situations, it is advantageous for 
DX NetOps Spectrum
 to retain the interface modeling information rather than immediately destroying them. This prevents useful model-specific attributes and resolved connections from being lost.
 
DX NetOps Spectrum
 determines that an interface model is stale when no corresponding entry exists in the MIB where the interface is defined. Once the stale interface ‘ages out’ 
DX NetOps Spectrum
 removes it from the model. The age out period for an interface is defined by the Stale Interface Age Out attribute (in minutes) on the device model.
An event is generated when 
DX NetOps Spectrum
 determines an interface is stale. If the stale interface has resolved connections, a minor alarm is generated on the interface model. If 
DX NetOps Spectrum
 determines that the interface is no longer stale before the age out period expires, and prior to a reconfiguration which causes the interface model to be destroyed, an event is generated and any stale interface alarm is cleared.
  •  
    Enable Stale Interface Alarms
    Set this attribute to Yes to enable 
    DX NetOps Spectrum
     to generate a minor alarm on an interface model when the interface becomes stale and it has resolved connections. Set this attribute to No if you do not want this condition to generate an alarm.
  •  
    Stale Interface Age Out (min)
    This attribute specifies the amount of time in minutes that 
    DX NetOps Spectrum
     waits for the stale interface to ‘age out’ before removing the model. To disable the stale interface functionality, set this attribute to 0.
    Default:
     120
