    connected two X670-G2 via DAC back to back to form a stack, serving as a core for edge switches

    now from edge which are X440-G2 two 10G links (LAG) connected to each X6702 switch

    configured LAG at x670 and x440

    X670 side

    enable sharing 1:1 grouping 1:1,2:1 algo address-based l2

    X440 side

    enable sharing 50 grouping 50-51 algo address-based l2

    connectivity is there but random dropping of ping packets performance is bad.. seems like a loop
    possible solution to control this situation??

    Can you post results from 'show sharing' from the 670 and 440?

    Please provide also :

    #show switch
    #show stacking

    You can look at storm control:
    show ports rate-limit flood

    and possible conectivity errors:
    show ports rxerrors port-number

    and for stacking ports:
    show ports stack-ports rxerrors

    Why dont you try to use lacp and l3_l4 like this:

    x670 -> enable sharing 1:1 grouping 1:1,2:1 lacp algo address-based l3_l4
    x440 -> enable sharing 50 grouping 50-51 lacp algo address-based l3_l4
