Configuring Capabilities Manager

Capabilities Manager discovers only whether a capability is supported on the local system. It does not discover whether the capability is configured or enabled, nor does it discover any other information about the capability for other devices in the network.

Capabilities information will be installed into the local Network Information Base (NIB) as Service Routing data and will be made available for advertisement by any SAF forwarder to the Service Routing network. Capabilities information is passed to the Service Routing infrastructure in XML format and is stored in the local NIB.

Capabilities Manager does not advertise capabilities information to the Service Routing network. A SAF forwarder distributes capabilities information. However, a SAF forwarder is not required in order for Capabilities Manager to function. If a SAF forwarder is not configured, the capabilities information is bound to the local device and is not distributed to other devices in the network. When a SAF forwarder is configured, it will distribute all capabilities information by default.

Capabilities information is installed in the Network Information Base (NIB) as Service Routing data. It is identified by a SAF address in the form of:

• Service ID--Capabilities Manager uses service ID 100.
• Subservice ID--Capability group ID. The subservice ID indicates the group ID of the capabilities data type.
• Instance number--Unique identifier for the local device. It is assigned in order of the hardware serial number, default MAC address, IPv4 device ID, or IPv6 device ID.

Capabilities Manager classifies capabilities by group to facilitate query and retrieval, and assigns each group a unique ID. Capabilities Manager provides the following capability groups:

• 1 (HARDWARE)
• 2 (SOFTWARE)

• Hardware Group Information
• Software Group Information

If you have an Extensible Messaging Client Protocol (XMCP) client (external client) connected to a SAF forwarder, you can subscribe to the Capabilities Manager, which is service ID 100. The data can be interpreted using the following XML schema:
