Hello Every body
I'm going to post my issue here
when I upgrade my virtual chassis from version 21.4R3-S3.4 to 21.4R3-S4.13, I lost part of the conf of member 1's em0.0 logical interface, as you can see in the diagram below.

Could someone please tell me how to reconfigure the interface?
thanks in advance
