Hi,
Is there a quick way to obtain the performance counter for each VL on each
port? I saw there are optional performance management attributes (such as
PortVLOpPackets, PortVLOpData) from IB spec. Do Mellanox CX2 PMA and
Infiniscale-IV switch support those performance management MAD? Thanks in
advance for your help.
Thanks,
Wei Lin

For IS4 you can query per SL receive/transmit counters, see the man pages of vendstat for the initialization and perfquery for the usage Or. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 3+ messages in thread
