bv su (in allClosed mode on Layer 3 switches and modules)

Important Considerations

■The summary display lists the physical ports that are associated with each VLAN interface. It does not indicate bridge port characteristics (for example, trunked ports). See “bridge vlan detail” next for this information.

■The VLAN mode (shown in the Type field) affects VLANs as follows:

■For the CoreBuilder 3500, CoreBuilder 9400, SuperStack® II Switch 3900, and SuperStack II Switch 9300, the VLAN mode affects all configured VLANs on the system. For the entire system, the default VLAN mode is allOpen.

■For the CoreBuilder 9000, the VLAN mode affects all VLANs that are associated with a particular module (the switch fabric module, or all VLANs on a switching module). For each module, the default VLAN mode is allOpen.

■As of Release 3.0.0, the CoreBuilder 3500 system and

CoreBuilder 9000 Layer 3 modules support one of three origins for a VLAN:

■If you explicitly create the VLAN with a bridge vlan define operation, the origin of the VLAN is static.

■If you create a router port IP interface (for which the system automatically creates a router port VLAN), the origin of the router port VLAN is router.

■If you enable dynamic port-based VLAN configuration via the GARP VLAN Registration Protocol (GVRP), the origin is GVRP.
