Why inpath0_0 bandwidth is 10Mbps?

Since Riverbed Steelhead CX1555 was added to my NMS/SolarWinds, noticed over 200% receive/transmit traffic on inpath0_0 interface ?? Wow~

We know inpath0_0 is a virtual interface. Both physical interfaces, WAN0_0 and LAN0_0, report 1Gbps.
Googling a few minutes, I got some answer from Riverbed support team said "it always has been 10Mbps…." They recommended that monitoring physical ports instead the inpath0_0 or inpath0_1.

In sort, instead of removing the port from SolarWinds NMS, I just edited interface properlty with "custom Bandwidth" to 1000Mbps.
 

Finally, no more RED alerts.

I hope Riverbed would fix it in near future and I hope it is informative for you.
