yes, there's no reason for connected mode to behave differently wrt to QoS/SL assignment from the SM, as both modes get their SL from the path record provided by the SM and both mode use the same code for the path query... > Have you checked that in this mode you do get the right > SL for each child interface by shutting off the relevant > SL (mapping it to VL15)? seeing what SL is provided by the SM in return to the path query is trivial, either through the opensm logs or the ipoib ones, e.g here you see that ib1 got SL 0 on its Path to GID fe80:0000:0000:0000:0008:f104:0399:3c92 LID 0x0006 which is 10.10.0.91 > ifdown ib1 > echo 1 > /sys/module/ib_ipoib/parameters/debug_level > ifup ib1 > ping 10.10.0.91 > dmesg | grep ib1 > ib1: Start path record lookup for fe80:0000:0000:0000:0008:f104:0399:3c92 MTU > > 0 > ib1: PathRec LID 0x0006 for GID fe80:0000:0000:0000:0008:f104:0399:3c92 > ib1: Created ah ffff81021ddda180 > ib1: created address handle ffff81021ddda500 for LID 0x0006, SL 0 > # ip neigh show dev ib1 > 10.10.0.91 lladdr 80:00:00:49:fe:80:00:00:00:00:00:00:00:08:f1:04:03:99:3c:92 > REACHABLE -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
