LAG should work fine b/w SX1036 and the SN2700 switch. Only for MLAG we have the limitations of the cpu which should match for both the switches.
Can you please verify your configs?
Is this a regular LACP port channel b/w both the switches.
What is the status of the second port which you are bundling in a LACP? Is it up/down/suspended?
Please share me the details.
We're not using LACP. We actually got it working by changing the port mode to "hybrid" instead of "trunk". All of our other LAG links work fine in trunk mode. We figure there's a misconfiguration somewhere in our system causing this, but we have a bunch of switches running at this point. The hybrid workaround has bumped this pretty low on the priority queue, particularly as any debugging would likely bring down a link critical to production work. But I'm all ears if somebody has an idea why we have this issue. Thanks.
