IBND_DISCOVER_FABRIC(3) OpenIB Programmer's ManualIBND_DISCOVER_FABRIC(3)
ibnd_discover_fabric, ibnd_destroy_fabric, ibnd_debug
ibnd_show_progress - initialize ibnetdiscover library.
#include <infiniband/ibnetdisc.h>
ibnd_fabric_t *ibnd_discover_fabric(struct ibmad_port *ibmad_port, int timeout_ms, ib_portid_t *from, int hops)
void ibnd_destroy_fabric(ibnd_fabric_t *fabric)
void ibnd_debug(int i)
void ibnd_show_progress(int i)
int ibnd_set_max_smps_on_wire(int i)
ibnd_discover_fabric() Discover the fabric connected to the port
specified by ibmad_port, using a timeout specified. The "from"
and "hops" parameters are optional and allow one to scan part of a
fabric by specifying a node "from" and a number of hops away from
that node to scan, "hops". This gives the user a "sub-fabric"
which is "centered" anywhere they chose.
ibmad_port must be opened with at least IB_SMI_CLASS and
IB_SMI_DIRECT_CLASS classes for ibnd_discover_fabric to work.
ibnd_destroy_fabric() free all memory and resources associated
with the fabric.
ibnd_debug() Set the debug level to be printed as library
operations take place.
ibnd_show_progress() Indicate that the library should print debug
output which shows it's progress through the fabric.
ibnd_set_max_smps_on_wire() Set the number of SMP's which will be
issued on the wire simultaneously.
ibnd_discover_fabric() return NULL on failure, otherwise a valid
ibnd_fabric_t object.
ibnd_destory_fabric(), ibnd_debug() NONE
ibnd_set_max_smps_on_wire() The previous value is returned
Discover the entire fabric connected to device mthca0 , port 1.
int mgmt_classes[2] = {IB_SMI_CLASS, IB_SMI_DIRECT_CLASS};
struct ibmad_port *ibmad_port = mad_rpc_open_port(ca,
ca_port, mgmt_classes, 2); ibnd_fabric_t *fabric =
ibnd_discover_fabric(ibmad_port, 100, NULL, 0); ...
ibnd_destroy_fabric(fabric);
mad_rpc_close_port(ibmad_port);
Discover only a single node and those nodes connected to it.
