Hi, team:

I make a test of switch S6720-50L-HI-48S and I would like to enable some loop detection mechanism, but working based on specific vlan, not whole interface, e.g. loop detected in vlan 100 should block traffic only in vlan 100.

The loop detection mechanism must also work for vlans on which mapping is performer, e.g. if we configured on interface: port vlan-mapping vlan 33 map-vlan 23, a loop in vlan 23 has to be detected.

Could you offer me a mechanism that will meet our expectations?

Thanks!

I think that the best way to be protected in this scenario is to use MSTP and if this is not possible then you can use smart link.
