We have 2 ICX7250 units stacked and we have 2 7750’s in a multi-chassis trunk. We are trying to connect 2 10GB ports from each 7250 to a 7750 so that we have a full ring. Currently I can only get a lag group on the 7250’s to come up if they are set to static, even then I’m only able to enable the lag from one of the 7250’s, if I do enable the ports on both then it appears as if a loop occurs. If I change the lag to dynamic then it looks like it’s up on the 7750 side but it is blocking on the 7250 side. Below I have posted the 7250 config and one of the 7750 configs (they are identical) to see if anyone has some suggestions.7250:ver 08.0.61aT213!stack unit 3 module 1
