NOTE Chapter 2 DLPI Primitives Local Management Primitives The provider responds to the request with a DL_PHYS_ADDR_ACK if the request is supported. Otherwise, a DL_ERROR_ACK is returned. Reasons for Failure DL_NOTSUPPORTED The primitive is known, but not supported by the DLS provider. DL_OUTSTATE The primitive was issued from an invalid state. The HP Auto Port Aggregation (HP APA) product allows grouping of networking links to form a single high bandwidth, highly available and scalable networking link, called an aggregate interface. HP APA also allows formation of a failover group of networking links connected across switches for an highly available link configuration on the server. For information on HP APA performance and scalability, see http://docs.hp.com/en/7662/new-apa-white-paper.pdf. HP APA exposes logical PPAs (Physical Points of Attachment) corresponding to the 'aggregate' or failover group. PPA is a unique integer identifier for each network physical port installed on the server. In HP-UX 11i v3, the APA PPA values are in the range 900 - 949. DL_PHYS_ADDR_ACK This primitive returns the value for the physical address to the link user in response to a DL_PHYS_ADDR_REQ. Format The message consists one M_PROTO message block containing the structure shown below. typedef struct { ulong dl_primitive; ulong dl_addr_length; ulong dl_addr_offset; } dl_phys_addr_ack_t; Parameters dl_primitive 95
