Thanks for quick response. I have tried changing it to single '=' and from cli my config looks like
admin(config)# xyz_configs xyz_name sample1 xyz 3 aaa [ 1 2 3 ] status enabled
Aborted: xyz_configs xyz_name sample1 aaa' (value "1"): Number of elements in aaa must be equal to number of xyz
what am I doing wrong here. I was expecting it to take since aaa list has 3 elements which is equal to xyz value '3' ?
