  • Hot Standby Router Protocol (HSRP) States: click here.

      Active - Indicates the router is forwarding packets that are sent to the router redundancy group.

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

      Initial - Indicates HSRPHot Standby Router Protocol is not running. This state occurs when an interface first comes up.

      Learn - Indicates the router has not yet determined the virtual IP address. This state occurs when the router is waiting to hear from the active router.

      Listen - Indicates the router knows the virtual IP address, but it is neither the active nor standby router. In this state, the router is waiting for a message from the active and standby routers.

      Speak - Indicates the router knows the virtual IP address. In this state, the router sends periodic messages and is ready to become an active or standby router.

  • Virtual Router Redundancy Protocol (VRRP) States: click here.

      Master - Indicates the router is forwarding packets that are sent to the router redundancy group.

      Backup - Indicates the router is a candidate to become the next master router.

      Initialize - Indicates the router is not running VRRP protocol. This state occurs when an interface first comes up.

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.

  Other – The SNMP agent responded with a value for the MIB variable used to determine the Router Redundancy Member State that is not recognized. 

Previous State The previous State of the Router Redundancy Member. State values are protocol-specific. For examples, see Current State.
State Last Modified Date and time the Router Redundancy State was last modified.

Tracked Objects Tab (NNMi Advanced)

[This is the Context-Sensitive Help topic for the Router Redundancy Member form, Tracked Objects tab.] 

A tracked object is the outbound interface responsible for delivering the outbound information packet that was originally sent to a selected inbound interface on a router that is part of the Router Redundancy Group. A Router Redundancy Member can have one or more associated tracked objects

The Router Redundancy Member Form provides details about the selected Router Redundancy Member. Each Router Redundancy Member is a router in the Router Redundancy Group.

For information about each tabConcept Link IconSee Also

See Tracked Objects Form (NNMi Advanced) for more information about tracked objects.

Tracked Objects Table

Attribute

Description

Name

Name of the selected router and its associated interface that is a member of the current Router Redundancy Group.

NNMi determines this Name value.

The name includes the fully-qualified DNS hostname assigned to the router and the Name attribute value that NNMi assigned to the interface.

This name appears in the following format:

<fully qualified hostname assigned to the router>[Interface Name]

For example:  HSRPRouter1.abc.example.com[Se1/1]

NNMi determines this Name value. See Node Form for more information about node names. See Interface Form for more information about interface names.
Track Priority

Number NNMi uses to rank the tracked object whenever a Current State change occurs. NNMi uses this number indirectly in the calculation to determine the next Primary member of the Router Redundancy Group.

When a tracked object goes down, the priority of the tracked object (Track Priority) is subtracted from its Router Redundancy Member Priority value to produce a smaller member Priority number. If this new Priority number is smaller than one of the other member Priority numbers, the member with the highest Priority value becomes the new Primary router in the Router Redundancy Group.

For example, if an interface that has a Track Priority of 20 goes down on a Router Redundancy Member that has a member Priority of 250:

  • The Track Priority (20) is subtracted from its member Priority (250-20=230).
  • The new member Priority (230) is then compared to the Priority value of the other members in the Router Redundancy Group.
  • If one of the members in the Router Redundancy Group has a higher member Priority, for example, 240, that member becomes the Primary router in the group (for example, HSRP Active or VRRP Master).
State Last Modified The date and time when the State value was last modified.

Tracked Objects Form (NNMi Advanced)

[This is the Context-Sensitive Help topic for the Tracked Object form.] 

Your network administrator might have set up groups of redundant routers to help ensure that information packets reach their intended destination. A tracked object is the outbound interface responsible for delivering the outbound information packet that was originally sent to a selected inbound interface on a router that is part of the Router Redundancy Group. A Router Redundancy Member can have one or more associated tracked objects.

Basics Attributes
Attribute Description
Name

Name used to identify the selected Tracked Object. The name includes the fully-qualified DNS name assigned to the Router and the name assigned to its associated Tracked Object .

NNMi determines this Name value.

The name includes the fully-qualified DNS hostname assigned to the router and the Name attribute value that NNMi assigned to the interface.

This name appears in the following format:

<fully qualified hostname assigned to the router>[Interface Name]

For example:  HSRPRouter1.abc.example.com[Se1/1]

See Node Form for more information about node names. See Interface Form for more information about interface names.

To find out more information about this interface: 

Click the  Lookup icon and choose one of the following options:

  •  Show Analysis to view the Analysis Pane information for the selected Tracked Object. (See Use the Analysis Pane for more information about the Analysis Pane.
  •  Open to open the Interface form.
Track Priority

Number used to rank the tracked object. This number is used indirectly in the calculation that determines the next Active or Master member of the Router Redundancy Group whenever a State change occurs.

When a tracked object goes down, the priority of the tracked object (Track Priority) is subtracted from its Router Redundancy Member Priority value to produce a smaller member Priority number. If this new Priority number is smaller than one of the other member Priority numbers, the member with the highest Priority value becomes the new Master or Active router in the current Router Redundancy Group.

For example, if an interface that has a Track Priority of 20 goes down on a Router Redundancy Member that has a member Priority of 250:

  • The Track Priority (20) is subtracted from its member Priority (250-20=230).
  • The new member Priority (230) is then compared to the Priority value of the other members in the Router Redundancy Group.
  • If one of the members in the Router Redundancy Group has a higher member Priority, for example, 240, that member becomes the Active or Master router in the group.
State Last Modified Date and time the Tracked Object State was last modified.

Registration Tab (NNMi Advanced)

[This is the Context-Sensitive Help topic for the Router Redundancy Group form, Registration tab.]

The Router Redundancy Group Form provides details about a managed connection.

For information about each tabConcept Link IconSee Also

Registration Attributes
Attribute Description

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.
Object Identifiers Attributes
Attribute Description

ID

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

UUID

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