ICX7250 Stack Lag group to a 7750 MCT LAG

andy_gee_kvap1c — Tue, 29 May 2018 12:23:30 GMT

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.

Your post got flagged as possible SPAM Andy, maybe you can share only the interfaces/config pertinent to your question (next time pls)?

Yes sorry about that. I got it working though, I had to change the lags on both sides to dynamic instead of static. We are good to go now.
