Attributes for OSPFInterface lists some key attributes for OSPFInterface. Network Protocol Manager for OSPF uses these and other attributes to diagnose OSPF interface problems and to detect OSPF interface events.

Table 1. Attributes for OSPFInterface

Attribute

Description

Allowed values

AdminStatus

Administrative status of this OSPF interface.

String:

  • UNKNOWN

  • ENABLED

  • DISABLED

AuthKey

Authentication key for simplePassword authentication for this OSPF interface.

Octet String

AuthType

Type of authentication used by this OSPF interface.

String:

  • NONE

  • SIMPLE_PASSWORD

  • MD5

  • OTHER

DeadInterval

For the device for this OSPF interface, number of seconds during which the router’s Hello packets have not been received before the router’s neighbors declare the device down.

Integer

Should be some multiple of the Hello interval and must be the same for all devices attached to a common network.

HelloInterval

Length of time, in seconds, between the Hello packets that the device sends on this OSPF interface.

Integer

Must be the same for all devices attached to a common network.

IfEventCount

Number of state changes or error events on this OSPF interface.

Integer

IfState

Current state of this OSPF interface.

String:

  • UNKNOWN

  • DOWN

  • LOOPBACK

  • WAITING

  • POINT_TO_POINT

  • DESIGNATED_ROUTER

  • BACKUP_DESIGNATED_ROUTER

  • OTHER_DESIGNATED_ROUTER

IfType

Type of this OSPF interface.

String:

  • BROADCAST

  • NBMA

  • POINT_TO_POINT

  • POINT_TO_MULTIPOINT

IPAddress

IP address of this OSPF interface.

String: IpAddress, an application-wide type that represents a 32-bit value

IsBDR

True if the device for this OSPF interface is a Backup Designated Router (BDR).

Boolean: true or false

IsDR

True if the device for this OSPF interface is a DR.

Boolean: true or false

IsPassive

True if this OSPF interface is passive—not in use.

Boolean: true or false

MulticastForwarding

Way in which multicasts are forwarded on this OSPF interface. Data link multicasting is not meaningful on NBMA or point-to-point interfaces.

String:

  • DISABLED

  • BLOCKED

  • MULTICAST

  • UNICAST

PollInterval

For this OSPF interface, the larger time interval, in seconds, between the Hello packets sent to an inactive NBMA neighbor.

Integer

RouterID

A 32-bit integer that uniquely identifies the device on which this OSPF service is running.

String: IpAddress, an application-wide type that represents a 32-bit value

RouterPriority

Priority assigned to the device of this OSPF interface, used in multi-access networks for the DR election algorithm.

Integer

0 signifies that the device is not eligible to become the DR on this particular network segment. If the devices on a network segment have the same priority, the devices use their router ID to determine the DR.

TransitDelay

Estimated number of seconds to transmit a link-state update packet over this OSPF interface.

Integer
