Unicast IP relies on ARP and IPoIB ARPs use the broadcast multicast group, so IB multicast does work on your setup... to see what IB multicast groups are being joined by your IPoIB devices, you can use the ipoib debugfs entries $ mount -t debugfs none /sys/kernel/debug $ cat /sys/kernel/debug/ipoib/ibxxx_mcg see Documentation/infiniband/ipoib.txt for more info Or. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
