Reviewing the Configuration for NIC Realms

NIC realms organize resolvers that perform a series of resolution tasks. Typically, you do not need to change the configuration for NIC realms.

To use SDX Configuration Editor to review the configuration for NIC realms:

1. In the navigation pane, select a configuration file for NIC.
2. Select the Realms tab, and expand the Realm section.
3. Review the transitions (sequential resolutions) in the Meta Graph Transitions section.

The transition has the format property=value.

If you want to qualify a property or value in a transition:

1. Select a transition.
2. Edit the entry.
3. Click Modify.

See NIC Resolution Transition Fields.

4. Expand the Resolvers section.
5. Review the configuration for resolvers to the realm.

See NIC Resolvers Fields.

NIC Resolution Transition Fields

In the Realm section of the Realms pane in SDX Configuration Editor, you can view the transitions (sequential resolutions) that occur in the resolution process. The following fields define the transitions.

Property

• Sequential number of the transition
• Value—Integer
• Example—2
• Property name—<number>

Value

• Transitions that define the resolution process.
• Value—List of transitions, each of which has the format <key> ':' <value> ':' <role> ':' ('[<'constraint'>]' (,'['<constraint>']')*)* ':' '*'

• ''—Literal value, for example ':' means a colon
• <key>—Data type that is the key for the resolution process
• <value>—Data type that is the value for the resolution process
• <role>—Name of the resolver that handles this resolution process
• ( )—Optional elements
• <constraint>—Mandatory or optional condition that must or may be satisfied before the next stage of the resolution process can proceed. For dynamic constraints, <constraint> is the data type for the constraint (for example: IpPool). For static constraints, <constraint> has the format <type>=<value>.

• type—Data type for the constraint.
• value—Value to check against. Must be in the proper format expected by the data type (for example: Domain=virneo.com).
• Append a '?' to the constraint if the constraint is optional.
• *—Operator that specifies that the resolver should accept the first response if it obtains information from multiple resolvers

• Example—2=IpPool:Vr:L3:[IpPool][Domain?]

NIC Resolvers Fields

In SDX Configuration Editor, you can modify the following fields in the Resolvers section of the Realms pane in a NIC configuration file.

Resolver Role

• Role that this resolver executes.
• Value—Name of the role defined in the Meta Graph Transitions table at the top of the Realm section.
• Example—RoleA

Resolvers List

• Names of NIC resolvers to which this resolver forwards events.
• Value—List of paths to NIC resolvers; paths are relative to the Static Configuration object and are separated by commas

Roles List

• Names of NIC roles to which this resolver forwards events.
• Value—List of roles separated by commas
• Example—RoleA
