Chassis Form

The name of the chassis. Sometimes it’s the descriptive string used by the network administrator to name the chassis. For example, C2950T, H3C S7503E, and Unit #2 S9505E.

If the Name value is null, NNMi uses the Component Identifier value (see Chassis Form: General Tab).

The node using this chassis or the node assigned to the Agent that is managing this chassis. This is the current value in NNMi’s database for the Name attribute of the host node. The value could be a DNS name, a MIB-II sysName, or an address (depending on how your NNMi administrator configured the discovery process).

Click the  Lookup icon and select Show Analysis or  Open to display more information about the node.

Overall status for the current chassis. NNMi follows the ISO standard for status classification. See the Chassis Form: Status Tab for more information. Possible values are:

  Normal

  Warning

  Minor

  Major

  Critical

  Unknown

  No Status

Chassis status is derived from polling results for Administrative State, Operational State, and the most serious outstanding conclusion. See the Chassis Form: Conclusions Tab for information about how the current status was determined. See Watch Status Colors for more information about possible status values.

The icons are displayed only in table views.

The calculated Management Mode for the chassis according to the Management Mode Hierarchy. This value reflects the current management mode of this chassis's parent object (either the Parent Component chassis or the Managed By node). See How NNMi Assigns the Management Mode to an Object.

(NNMi Advanced - Global Network Management feature) Any change to this Management Mode setting is sent from a Regional Manager to the Global Manager during the next Spiral Discovery cycle on the Regional Manager.

Indicates whether or not NNMi is currently monitoring the chassis. Possible values are:

Inherited – Used to indicate that the chassis should inherit the Management Mode from the chassis's parent object (either the Parent Component chassis or the Managed By node).

  Not Managed – Used to indicate that NNMi does not discover or monitor the chassis.

Out of Service – Used to indicate the chassis is unavailable because it is out of service or participating in a Scheduled Node Outage. NNMi does not discover or monitor this Chassis.

NNMi administrators and Level 2 Operators can use the drop-down selection list to change the current setting.

If you change the Direct Management Mode using Actions → Management Mode, NNMi updates the calculated Management Mode on the form. If you manually set the Direct Management Mode and then Save your changes, the Management Mode value is not updated until you refresh the form.

Either the current chassis Administrative State value. The NNMi State Poller interprets and normalizes the State value returned for the monitored attribute to handle the differences between vendors. The current Administrative State contributes towards the status calculation for this chassis. See the Chassis Form: Status Tab for more information.

Possible values are:

  Up – The SNMP agent responded with a chassis administrative status value of Up.

  Down – The SNMP agent responded with a chassis administrative status value of Down.

  Other – The SNMP agent responded with a value for chassis administrative status that is not recognized.

The following values indicate NNMi could not gather the required data:

  Agent Error – Indicates an error was returned in response to the query.

  No Polling Policy - No polling policy exists for this monitored attribute.

  Not Polled - Indicates that this attribute is intentionally not polled, based on current Monitoring Configuration settings, current Communication Configuration settings, or because the parent Node is set to Not Managed or Out of Service. This object attribute might or might not have an associated polling policy.

  Not Provided — The device does not support providing information for this monitored attribute.

 Unavailable - The agent responded with a value outside the range of possible values or returned a null value.

  Unset – Currently not used by NNMi.

The current chassis Operational State value.  The NNMi State Poller interprets and normalizes the State value returned for the monitored attribute to handle the differences between vendors. The current Operational State contributes towards the status calculation for this chassis. See the Chassis Form: Status Tab for more information.

Possible values are:

 Up – The SNMP agent responded that the chassis is operationally up, ready to receive and send network traffic.

 Disabled – The chassis's Administrative State is set to  Down.

  Down – The SNMP agent responded that the chassis is operationally down.

  Dormant – Indicates the chassis is in a "pending” state, waiting for some external event.

  Minor Fault – Indicates that the chassis or one of its hardware components is experiencing a partial failure.

  Not Present – Indicates that the chassis module is not installed or is missing.

  Other – The SNMP agent responded with a value for chassis operational status that is not recognized.

  Testing – The SNMP agent responded that the chassis is in test mode.

  Transient – Indicates the chassis is in a transient state. For example, rebooting.

  Unknown – The SNMP agent responded with a chassis operational status value of unknown.

The following values indicate NNMi could not gather the required data:

  Agent Error – Indicates an SNMP error was returned in response to an SNMP query to this agent.

  No Polling Policy - No polling policy exists in Monitoring Configuration settings for this monitored attribute.

  Not Polled - Indicates that this attribute is intentionally not polled, based on current Monitoring Configuration settings, current Communication Configuration settings, current polling policies, or because the parent Node is set to Not Managed or Out of Service

 Unavailable - The SNMP agent responded with a value for chassis operational status of Not-Specified, so NNMi is unable to determine the State. Other possibilities: the SNMP agent returned a value outside the range of possible values or returned a null value.

  Unset – Currently not used by NNMi.

Either the current MIB-II Standby State value or a value the NNMi State Poller interprets and normalizes to handle differences between vendors. The current Standby State contributes towards the status calculation for this chassis. See the Chassis Form: Status Tab for more information.

Possible values are:

  Active - Indicates the chassis is the active chassis in the Chassis Redundancy Group.

  Cold-Standby - Indicates the chassis is not in use, but is available to take over the role of the active chassis after it is initialized.

  Hot-Standby - Indicates the chassis is not in use, but can immediately take over the role of the active chassis.

  Standby - Indicates the chassis is a candidate to become the next active chassis.

  Error - Indicates the chassis cannot take over the role of active or standby chassis in the Chassis Redundancy Group.

  Other – The SNMP agent on the chassis responded with a value for Standby State of Other or one that is not recognized. 

  Transient – Indicates the chassis is in a transient state. For example, rebooting.

  Unknown - Indicates the chassis is unable to report Standby State.

The following values indicate NNMi could not gather the required data:

  Agent Error – Indicates an error was returned in response to the query.

  No Polling Policy - No polling policy exists for this monitored attribute.

  Not Polled - Indicates that this attribute is intentionally not polled, based on current Monitoring Configuration settings, current Communication Configuration settings, or because the parent Node is set to Not Managed or Out of Service. This object attribute might or might not have an associated polling policy.

  Not Provided — The device does not support providing information for this monitored attribute.

 Unavailable - The agent responded with a value outside the range of possible values or returned a null value.

  Unset – Currently not used by NNMi.

Minor Status Conclusions

Warning Status Conclusions

Unknown Status Conclusions

Normal Status Conclusions

Status is derived from the most serious outstanding Conclusion and SNMP polling results for Administrative State and Operational State.

The time of the last change in Status.

For more information about each conclusion, see the following:

• Chassis Form: Conclusions Tab

Created

Date and time the selected object instance was created. NNMi uses the locale of the client and the date and time from the NNMi management server.

This value does not change when a node is rediscovered. This is because the Node object is modified, but not created.

Last Modified

Date the selected object instance was last modified. NNMi uses the locale of the client and the date and time from the NNMi management server.

Note the following:

• When a node is rediscovered, the Last Modified time is the same as the Discovery Completed time. This is because the node’s Discovery State changes from Started to Completed.
• When a Node is initially discovered, the Last Modified time is slightly later than the Created time. This is because node discovery does not complete until after the Node is created.

ID

The Unique Object Identifier, which is unique within the NNMi database.

UUID

The Universally Unique Object Identifier, which is unique across all databases.
