Description
Use this command to test the backplane routing and VC allocation. This test
applies to single blade as well as multi-blade systems.
The following items are tested:
■
Proper back-end port domain routing setup such that every user port has a
valid path to every other user port. If a valid path does not exist between any
two user ports then that path will fail to transmit the first frame between the
two ports.
■
Proper VC mapping such that an arbitrarily large number of frames may be
transmitted without running out of credit. If the VC credit mapping is not
correct then the test will fail after enough frames have been sent to exhaust the
initial credit. VC mapping is not tested if the
extonly
operand is enabled.
■
Proper Trunking of backend ports. The frames are sent in bursts. If the
trunking is not set up properly the burst of frames will not arrive in order.
Note: Since the frames are received without “spinning” first, this test is not as
exhaustive as
spinFab
.
