VLANs are listed by their topologically distinct broadcast domains. A VLAN that is listed several
times means that the products on which the VLAN has been configured cannot communicate

these products. If FDP or LLDP is enabled, then each VLAN lists the products in that broadcast
domain.
VLANs, products, or ports quickly.
A VLAN may be listed several times. For example, the first three VLAN1s have only one product.
Each product in each VLAN is in its own broadcast domain and either does not have
connectivity with other products or FDP or LLDP is not enabled on that product.
