Portchannel fails on stacked 2960-s switch to UCS 200
I converted a set of switches last night (3650-lan base 12.2) to a new stack of qty 2 - 2960s (IOS 15 latest) with flexstack on them. They are connecting to a UCS 200 running CUCM and Unity, managed by VMWare w/o Virtualcenter. For whatever reason I had issues when I had the ports on different switches that were connected with flexstack (meaning when I had one port on 1/0/30 and another on 2/0/30 it would fail). When I put the ports onto one physical switch it worked fine.
Reading through the documentation I see that there are some issues with pagp and possibly lacp on multiple switches in a stack.
Can someone recommend a channel-mode for the port channels' configuration that will make it work across two physical switches? Seems dumb to use a flexstack if I can't break the load between both switches in case something happens.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
