SummitStack-V320 Stacking Bandwidth Capacity

[Mrxlazuardin]

Hi,

I'm still confused with SummitStack-V320 stacking bandwidth capacity. Isn't it 320Gbps (4x 80Gbps) full duplex bandwidth? Following is stacking information of two X670V-48T, each with VIM4-40G4X module.

I don't think that I can have 320Gbps full duplex stacking bandwidth because two ports are blocked due to stacking ring topology. Why two nodes stacking require ring topology on stacking? Can I disable stacking ring topology so I can have 320Gbps full duplex stacking bandwidth?

Best regards,

Hi, In a stacking ring topology there's no port blocked for unicast traffic, only for bum traffic.
