Can we explain the following counter..FCP_SW_CNTR_RX_WT_AVG_B2B_ZERO

We see it when looking for dropped packets on the ds-9248-256k9 port blades.

Hi,

FCP_SW_CNTR_RX_WT_AVG_B2B_ZERO is the average amount of times the RX buffer to buffer credits went to 0 on that interface.  If you are seeing the counter increasing it could be because of a slow drain device in the fabric.
