Interface Form

The Interface form provides details about the physical or virtual network interface selected. From this form you can access more details about the parent node, addresses, current network connection, and incidents associated with this interface.

If your role permits, you can use this form to modify the Management Mode for an interface (for example to indicate it will be temporarily out of service) or add notes to communicate information about this interface. This topic includes the following sections:

If you see several blank columns for an interface in a table view, note the following:

  • The interface might be in a non-SNMP node.

    For interfaces on non-SNMP nodes, note the following: 

    • The interface index (ifIndex) value is always set to 0 (zero).
    • The interface type (ifType) is set to Other.
    • The interface Name (ifName), if none is available, is set to Pseudo Interface.

      For Pseudo Interface, NNMi attempts to obtain additional information using a variety of discovery protocols (see the list of Topology Source protocols in Layer 2 Connection Form).

    • If the interface hosts an IP address, the interface Alias (ifAlias) is set to the IP address. Otherwise, the interface Alias (ifAlias) is set with information from neighboring SNMP devices.
    • NNMi obtains the MAC address if the IP address can be resolved using ARP cache.
  • The interface might be a Nortel private interface.

    For Nortel SNMP interfaces, note the following: 

    • The interface index (ifIndex) value is set according the Nortel private MIB.
    • NNMi tries to collect the MAC address and interface name using Nortel's private MIBs.
  • (NNMi Advanced) The interface might be an IPv-6 interface.

    A small number of IPv6 devices do not support the standard RFC 2863 IF-MIB for IPv6 interfaces. In this case, NNMi uses the RFC 2465 IPv6-MIB. When this happens, note the following:

    • Interface index (ifIndex) and description (ifDescr) are set according to the RFC 2465 IPv6 MIB.
    • Interface type (ifType) is set to Other (no specific type is available).
    • Interface Name (ifName), Alias (ifAlias), and Speed (ifSpeed) are blank (not available).
    • NNMi monitors the Status of this interface, but Performance metrics are not available.

    When an IP Address has the Interface Name (ifName) attribute set to blank, NNMi constructs an alternate string for the IP Address's In Interface attribute (Other[<ifIndex_value>]).

Basic Attributes
Attribute Description
Name The most accurate interface name available to the initial discovery process. First choice is the IF MIB ifName value. Second choice is the ifAlias value. Third choice is a combination of the ifType[ifIndex] value (for example, ethernetCsmacd[17]).
Status

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

  No Status

  Normal

  Disabled

  Unknown

  Warning

  Minor

  Major

  Critical

Interface status is derived from SNMP polling results for ifAdminStatus and IfOperStatus, as well as from any conclusions. Status reflects the most serious outstanding conclusion. See the Interface 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.

Management Mode

The calculated Management Mode for the interface according to the Management Mode Hierarchy. This value reflects the current management mode of this interface's parent object (the Hosted On 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.

If the NNMi Security configuration permits, you can change this setting using ActionsManagement Mode.You can also right-click any object in a table or map view to access the items available within the Actions menu.
Direct Management Mode

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

 Inherited – Used to indicate that the interface should inherit the Management Mode from this interface's parent object (the Hosted On Node).

  Not Managed – Used to indicate that NNMi does not discover or monitor the interface. For example, the interface might not be accessible because it is in a private network.

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

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 ActionsManagement 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.
Hosted On Node

The node in which the interface resides. This is the current value in the NNMi database for the Name attribute of the host device. 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.

Physical Address

The interface address at the physical layer, also known as the MAC address. This is the globally unique serial number assigned to each interface at the factory.

Layer 2 Connection

Used to indicate whether the selected interface is part of a Layer 2 Connection. If the interface is part of a connection, use this attribute to access information about its Layer 2 Connection and the neighboring device. Click here for instructions.

  1. Navigate to the Layer 2 Connection attribute. Click the Lookup icon, and select  Open.
  2. In the Layer 2 Connection form, locate the Interfaces tab.
  3. Double-click the row representing the other interface participating in this connection.

[This is the Context-Sensitive Help topic for the Interface form, General tab.]

The Interface Form provides details about the selected network interface.

For information about each tabConcept Link IconSee Also

General SNMP Values
Attribute Description
ifName

Optional Interface MIB variable for ifName () assigned to the interface by the vendor. If no IfName value is provided, SNMP uses the ifType+ifIndex which is dynamically configured and can change. This name is not guaranteed to be unique or consistent across reboots.

iIfAlias

Optional Interface MIB variable for ifAlias assigned to the interface. This value is set by the device administrator. An ifAlias could be useful if the interface vendor did not provide an ifName value.

ifDescr

Optional Interface MIB variable for ifDescr (1.3.6.1.2.1.2.2.1.2) for the interface. This attribute is set by the device administrator. 

ifIndex

Interface MIB variable for the row number in the interface table (ifTable) for this interface. The row number can change. If you are an Administrator, see Accurately Detect Interface Changes for more information.

Interfaces on non-SNMP nodes have an ifIndex value of 0 (zero).
ifSpeed

Interface MIB variable for the interface’s bandwidth in bits per second. Depending on the device vendor, this value might indicate current speed or potential speed.

ifType

Interface MIB variable for the physical link protocol type of the interface. Possible values include: Ethernet and frameRelay.

Interfaces on non-SNMP nodes have an ifType value of other.

Requires Network Node Manager iSPI Performance for Metrics Software (NNM iSPI Performance for Metrics). To populate performance data in the dashboard views or enhance NNM iSPI Performance for Metrics reports by sharing NNMi configuration settings, install the optional Network Performance Server (NPS).

Input Speed

(NNM iSPI Performance for Metrics) If the Network Node Manager iSPI Performance for Metrics Software is installed and configured within your environment, you can type an integer value to override the input speed value returned by the device's SNMP agent. Indicate the speed this interface is capable of receiving data in bits per second.

For example, you might want to override the Input Speed value for the following reason:

Sometimes the value returned by the device's SNMP agent is not accurate or causes problems when NNM iSPI Performance for Metrics calculates performance monitoring. For example, the input speed might be restricted due to circumstances in your environment, or bandwidth controls might limit the connection speed regardless of what the physical connection is capable of (such as within a WAN).

(NNMi Advanced - Global Network Management) If you change this value for an Interface monitored by a Regional Manager, NNMi forwards the updated information to the Global Manager at the next Discovery Interval.

If you are an NNMi administrator, you can set input speeds for multiple interfaces using the nnmsetiospeed.ovpl command. Also see "Maintaining NNMi" in the Network Node Manager i Software Deployment Reference for more information.

Output Speed

(NNM iSPI Performance for Metrics) If the Network Node Manager iSPI Performance for Metrics Software is installed and configured within your environment, you can type an integer value to override the output speed value returned by the device's SNMP agent. Indicate the speed this interface is capable of transmitting data in bits per second.

For example, you might want to override the Output Speed value for the following reason:

Sometimes the value returned by the device's SNMP agent is not accurate or causes problems when NNM iSPI Performance for Metrics calculates performance monitoring. For example, the output speed might be restricted due to circumstances in your environment, or bandwidth controls might limit the connection speed regardless of what the physical connection is capable of (such as within a WAN).

(NNMi Advanced - Global Network Management) If you change this value for an Interface monitored by a Regional Manager, NNMi forwards the updated information to the Global Manager at the next Discovery Interval.

If you are an NNMi administrator, you can set output speeds for multiple interfaces using the nnmsetiospeed.ovpl command. Also see "Maintaining NNMi" in the Network Node Manager i Software Deployment Reference for more information.

  • NNMi administrators can associate custom information with the Interface for their network management team's benefit.

    For example, your NNMi administrator might have added the following:

    • Name: Assignment
    • Value: WAN interface to the London office.
  • External applications that have been integrated with NNMi can associate custom information with the Interface.

    For example, when Network Node Manager iSPI Performance for Metrics Software is installed, your NNMi administrator can provide additional Node or Interface information in NNM iSPI Performance for Metrics reports:

    • Name = NPS Annotation
    • Value = <text to appear in the reports>.

    See the help topic: Annotate NNM iSPI Performance for Metrics Reports.

  • NNMi can associate custom information about an Interface.

    For example, if the NNMi administrator enables the Discovery and Monitoring of unnumbered interfaces, you will see this Custom Attribute associated with each unnumbered interface:

    • Name: UnnumberedNextHop
    • Value: <IP address of the neighboring device>

(NNMi Advanced - Global Network Management feature) Custom Attribute values can be replicated from a Regional Manager (NNMi management server) to the Global Manager. NNMi administrators for the Global Manager configure which Regional Custom Attributes they want (Global Manager: Configure Custom Attribute Replication). NNMi administrators can also configure Custom Attribute values that are unique to the Global Manager's environment (Customize Object Attributes).

Registration Tab

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

The Interface Form provides details about the selected network interface.

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.

Virtual Switch's Interface Form (NNMi Advanced)

Basic Attributes
Attribute Description
Name The most accurate interface name available to the initial discovery process. First choice is the IF MIB ifName value. Second choice is the ifAlias value. Third choice is a combination of the ifType[ifIndex] value (for example, ethernetCsmacd[17]).
Status

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

  No Status

  Normal

  Disabled

  Unknown

  Warning

  Minor

  Major

  Critical

Interface status is derived from SNMP polling results for ifAdminStatus and IfOperStatus, as well as from any conclusions. Status reflects the most serious outstanding conclusion. See the Interface 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.

Management Mode

The calculated Management Mode for the interface according to the Management Mode Hierarchy. This value reflects the current management mode of this interface's parent object (the Hosted On 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.

If the NNMi Security configuration permits, you can change this setting using ActionsManagement Mode.You can also right-click any object in a table or map view to access the items available within the Actions menu.
Direct Management Mode

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

 Inherited – Used to indicate that the interface should inherit the Management Mode from this interface's parent object (the Hosted On Node).

  Not Managed – Used to indicate that NNMi does not discover or monitor the interface. For example, the interface might not be accessible because it is in a private network.

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

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 ActionsManagement 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.
Hosted On Node

The node in which the interface resides. This is the current value in the NNMi database for the Name attribute of the host device. 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.

Physical Address

The interface address at the physical layer, also known as the MAC address. This is the globally unique serial number assigned to each interface at the factory.

Layer 2 Connection

Used to indicate whether the selected interface is part of a Layer 2 Connection. If the interface is part of a connection, use this attribute to access information about its Layer 2 Connection and the neighboring device. Click here for instructions.

  1. Navigate to the Layer 2 Connection attribute. Click the Lookup icon, and select  Open.
