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.
