A fault delegate object can be defined on IFC (for example, for an endpoint group) and when the fault is raised (for example, under an endpoint policy on a switch), a fault delegate object is created on IFC under the specified object. A fault delegate object follows the lifecycle of the original fault instance object, being created, modified, or deleted based on the changes of the original fault.

Properties Summary
Defined in: ospf:IfPol
ospf:IfCost
          scalar:Uint16
cost  (ospf:IfPol:cost)
           The OSPF cost for the interface. The cost (also called metric) of an interface in OSPF is an indication of the overhead required to send packets across a certain interface. The cost of an interface is inversely proportional to the bandwidth of that interface. A higher bandwidth indicates a lower cost. There is more overhead (higher cost) and time delays involved in crossing a 56k serial line than crossing a 10M ethernet line. The formula used to calculate the cost is: cost= 10000 0000/bandwith in bps For example, it will cost 10 EXP8/10 EXP7 = 10 to cross a 10M Ethernet line and will cost 10 EXP8/1544000 = 64 to cross a T1 line. By default, the cost of an interface is calculated based on the bandwidth; you can force the cost of an interface with the ip ospf cost value interface subconfiguration mode command.
ospf:IfControl
          scalar:Bitmask8
ctrl  (ospf:IfPol:ctrl)
           The interface policy controls.
ospf:DeadIntvl
          scalar:Uint16
deadIntvl  (ospf:IfPol:deadIntvl)
           The interval between hello packets from a neighbor before the router declares the neighbor as down. This value must be the same for all networking devices on a specific network. Specifying a smaller dead interval (seconds) will give faster detection of a neighbor being down and improve convergence, but might cause more routing instability.
ospf:HelloIntvl
          scalar:Uint16
helloIntvl  (ospf:IfPol:helloIntvl)
           The interval between hello packets that OSPF sends on the interface. Note that the smaller the hello interval, the faster topological changes will be detected, but more routing traffic will ensue. This value must be the same for all routers and access servers on a specific network.
naming:Name
          string:Basic
name  (ospf:IfPol:name)
           Overrides:pol:Obj:name | naming:NamedObject:name
           The OSPF interface policy name. This name can be between 1 and 64 alphanumeric characters. Note that you cannot change this name after the object has been saved.
ospf:NwT
          scalar:Enum8
nwT  (ospf:IfPol:nwT)
           The OSPF interface policy network type. OSPF supports point-to-point and broadcast.
ospf:IfPfxSuppress
          scalar:Enum8
pfxSuppress  (ospf:IfPol:pfxSuppress)
           prefix suppression
ospf:DesigPrio
          scalar:UByte
prio  (ospf:IfPol:prio)
           The OSPF interface priority used to determine the designated router (DR) on a specific network. The router with the highest OSPF priority on a segment will become the DR for that segment. The same process is repeated for the backup designated router (BDR). In the case of a tie, the router with the highest RID will win. The default for the interface OSPF priority is one. Remember that the DR and BDR concepts are per multiaccess segment.
ospf:RexmitIntvl
          scalar:Uint16
rexmitIntvl  (ospf:IfPol:rexmitIntvl)
           The interval between LSA retransmissions. The retransmit interval occurs while the router is waiting for an acknowledgement from the neighbor router that it received the LSA. If no acknowlegment is received at the end of the interval, then the LSA is resent.
ospf:XmitDelay
          scalar:Uint16
xmitDelay  (ospf:IfPol:xmitDelay)
           The delay time needed to send an LSA update packet. OSPF increments the LSA age time by the transmit delay amount before transmitting the LSA update. You should take into account the transmission and propagation delays for the interface when you set this value.
Defined in: pol:Def
naming:Descr
          string:Basic
descr  (pol:Def:descr)
           Specifies a description of the policy definition.
naming:Descr
          string:Basic
ownerKey  (pol:Def:ownerKey)
           The key for enabling clients to own their data for entity correlation.
naming:Descr
          string:Basic
ownerTag  (pol:Def:ownerTag)
           A tag for enabling clients to add their own data. For example, to indicate who created this object.

Constants
created 2u created In a setter method: specifies that an object should be created. An error is returned if the object already exists.
In the return value of a setter method: indicates that an object has been created.
modified 4u modified In a setter method: specifies that an object should be modified
In the return value of a setter method: indicates that an object has been modified.
deleted 8u deleted In a setter method: specifies that an object should be deleted.
In the return value of a setter method: indicates that an object has been deleted.
DEFAULT 0 --- This type controls the life cycle of objects passed in the XML API.

When used in a setter method (such as configConfMo), the ModificationStatus specifies whether an object should be created, modified, deleted or removed.
In the return value of a setter method, the ModificationStatus indicates the actual operation that was performed. For example, the ModificationStatus is set to "created" if the object was created. The ModificationStatus is not set if the object was neither created, modified, deleted or removed.

When invoking a setter method, the ModificationStatus is optional:
If a setter method such as configConfMo is invoked and the ModificationStatus is not set, the system automatically determines if the object should be created or modified.
