    Hi,
    How can I make Ring topology?
    I can't make Ring topology on 6300m vsf.
    Only Chin topology  is made.
    How can I make Ring topology?

    VSF information is as below.

    ----------Cable connect-------
    Connected DAC 1/1/27 to 2/1/28

    A VSF made by only two members admits only a Chain topology (Ring is not admitted with just two members only): on each VSF member you're free to aggregate physical links dedicated to logical VSF Link - respectively 1/1/27+1/1/28 on VSF Member 1 and 2/1/27+2/1/28 on VSF Member 2 - to enhance resiliency of the VSF interconnection between VSF members (sort of Link Aggregation).

    Thank you so much.

    I thought that even if there were two devices, making two vsf ports would make a ring.
    I'll use a lacp.
