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.

(in allOpen mode on Layer 2 or Layer 3 switches and modules)
b v 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
.
