I have two switches in stack.
The switches are X250e-24t and X440-48p.
The version is 184.108.40.206.
This stack has two ports in trunk configured in sharing to the switch core.
The spanning tree is not configured in this network.
One week ago I had a problem because there were a l2 loop.
I think it was a stack problem, causing the misconfiguration of the two ports in sharing and lease two trunk actived.
What do you think?
Are there problems if I do a stack with two platform different?
If I upgrade the version, Can I resolve this problem?
