You can display a summary of VLAN information or a detailed report. When you display a summary, you receive information about the protocols and ports assigned to each VLAN plus the layer 3 addresses used to manage ﬂood domains for overlapping IP subnetworks. The detailed VLAN report includes the summary information plus additional utilization statistics.

From the top level of the Administration Console, enter:

bridge vlan summary

or

bridge vlan detail

The VLAN information is displayed in the format you speciﬁed.
