CRS317-1g-16s+

Hiya

I have a CRS switch. It is not doing any routing. The only IP it has is for the management port.

We have a few ports bridged.

1 of which is our incoming 10G fibre. 3141 VLAN tagged on this port

That VLAN 3141 is in a BRIDGE with 2 other ports, SFP1 and SFP2.

HW Offload is enabled on the bridge.

It is absolutely killing the CPU at 500mbps.

Any recommendations?
