I have deployed some 2011's now. My standard setup is a 2011 at the top with a run of fiber coming down plugged into another 2011. I am trunking some VLANs across the SFPs. I have created VLANs on the 2011 by bridging the VLANs together. I have a VLAN on the SFP and one on the physical ethernet port. I then bridge these 2 vlans together.
I experience packet loss between the routerboards. Going through the routerboard to an ethernet device I experience packet loss as well. It does not matter what device so I can pretty much rule out it being specific to a certain device. I have tried turning auto negotiate off, on, duplex, etc.
This is happening on several locations so I can rule out something site specific.
Any ideas? Any notes in the 5.21 about 2011s? I am going to put files together and email support, but figured I would ask here 1st.
