VSF links: can some links be rearranged without issues?

     Cheers,

     

    I have a (silly) doubt...actually our Aruba 5400R zl2 VSF is deployed with this VSF Links configuration (4 DAC Cables = 4x10Gbps = 40 Gbps):

     

    VSF# show vsf link detail

VSF Member: 1 Link: 1

Port State
-------- ------------
1/C7 Up: Connected to port 2/C7
1/C8 Up: Connected to port 2/C8
1/D7 Up: Connected to port 2/D7
1/D8 Up: Connected to port 2/D8


VSF Member: 2 Link: 1

Port State
-------- ------------
2/C7 Up: Connected to port 1/C7
2/C8 Up: Connected to port 1/C8
2/D7 Up: Connected to port 1/D7
2/D8 Up: Connected to port 1/D8

    We realized that crossing some of the links (at least two - C8 and D8 on each VSF Member - of the total four each VSF Port has) would be better from the resiliency standpoint (in case one or two VSF Member's module(s) would hit a serious issue) leaving us - at worst - with one 10Gbps VSF Links between VSF Members:

Port State
-------- ------------
1/C7 Up: Connected to port 2/C7
1/C8 Up: Connected to port 2/D8
1/D7 Up: Connected to port 2/D7
1/D8 Up: Connected to port 2/C8


VSF Member: 2 Link: 1

Port State
-------- ------------
2/C7 Up: Connected to port 1/C7
2/C8 Up: Connected to port 1/D8
2/D7 Up: Connected to port 1/D7
2/D8 Up: Connected to port 1/C8

    So...can I rearrange /C8 and /D8 physical links (reseating related DAC Cables) leaving untouched /C7 and /D7 ones without any particular issue from the VSF Ports standpoint?

     

    The answer should be a sound "Yes"...but it worths a double check.

    Greetings!

     

    In the case of the 5400R, because there can only be one other member, you can connect any physical VSF port on one member to any other VSF port on the other member. You can even swap VSF ports while the stack is operating without causing an interruption in operation as long as at least one VSF link interface remains active at all times.

    Hello Matthew! thanks for confirming my very same toughts banishing my doubt...considering the special Aruba 5400R zl2 VSF deployment case...that was what I expected too. Great.
