IP MAC Binding and IP Source Guard

Hello everyone,

Using IP MAC Binding option in Policy Profile is just about creating a binding table for itself or it can be used as a trusted source for features like IP Source Guard?

Thanks

Hello @rezaalikhani

It’s not just for reference... enabling IP–MAC binding makes the Sw build a trusted binding table that other features like IP source guard (and DAI) actually use to validate traffic and block spoofing...
