bridge vlan summary Displays a summary of VLAN information. In a summary report, the
system displays the ports and protocols that are assigned to each VLAN.
Valid Minimum Abbreviations
b v s (in allOpen mode on Layer 2 or Layer 3 sw itches and modules)
b v su (in allClosed mode on Layer 3 switches and m odules)
Important Considerations
■The summary display lists the physical ports that are associated with
each VLAN interface. It does not indicate brid ge port characteristics
(for example, trunked ports). See “bridge vla n 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 m ode is allOpen.
■For the CoreBuilder 9000, the VLAN mode affects all V LANs 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 o f three origins for a
VLAN:
■If you explicitly create the VLAN with a bridge vlan define
operation, the origin of the VLAN is stati c.
■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 o rigin is GVRP
.
