The value the switching system is using to represent itself as this node. This object may only be written when pnniNodeAdminStatus has the value down.

This attribute determines the setting of the nodal representation bit in the nodal information group originated by this node.

Indicates whether the node is able to support additional point-to-multipoint branches. A value of 'false' indicates that additional branches can be supported, and a value of 'true' indicates that additional branches cannot be supported.

The pnniIfTable contains the attributes necessary to configure a physical interface on a switching system which is capable of being used for PNNI routing. Interfaces may represent physical connection points (i.e. copper/fiber connection points) or VPCs which have been configured for PNNI's use. Each interface is attached to a specific lowest-level node within the switching system. An ifIndex is used as the instance ID to uniquely identify the interface on the local switching system.
