We are using Extreme x440 1Gbps switch and Sonicwall for Providing internet to our users. Recently we have been upgraded to 2Gbps of Internet bandwidth. So, we have enabled the Link Aggregation in Port 1 and 2 to receive the 2Gbps Internet from ISP. To share this to our users we have to connect it to Sonicwall. So, we have enabled the Link aggregation in Sonicwall. So, again we have created a link aggregation in Switch ports 9 and 10. We have taken two cables from these two ports and connected it to Sonicwall. While enabling this LAG between Sonicwall and 9 and 10 the entire traffic goes down. Normally our traffic will be around 850 to 970Mbps. After enabling this LAG it goes to 2Mbps. We don't know where the actual problem is? Whether it is in Sonicwall or Extreme Switch side. Need a idea to fix this issue. Thanks in advance.

The SonicWALL's only support static LAG's. How did you build the LAG on the extreme side (what does your sharing command look like)? Also, what SonicWALL model? You'll need a pretty hefty SonicWALL to run at that speed with the security services enabled.
