LAN (VLAN )

Field Description
Origin For all Layer 2 systems or switching modules, the VLAN origin is
always static, which indicates that the user created the VLAN.
For the CoreBuilder
indicates one of the following:
static — The VLAN was created statically (user-configured
by using the bridge vlan define command).
router — The VLAN was created automatically by a outer port
IP interface (of router origin). You create a router port IP
interface using the ip interface define command with
the interface type port. You cannot modify or remove a router
port VLAN.
GVRP — The VLAN was created dynamically from a GVRP
update (GVRP). You must enable the GVRP state for the entire
system as a bridge-wide parameter and for the participating
bridge ports as a bridge-port parameter.
Ports Index numbers of the bridge ports that belong to the VLAN, or the
bridge port that belongs to the router port IP interface.
On the CoreBuilder 9000, the list of ports includes the front-panel
ports and the appropriate backplane ports. Example: On a 12-port
Layer 3 module, the list of ports includes ports 1 – 12 and port 13,
which is the module's backplane port.
Type (VLAN Either allOpen or allClosed. VLANs in allOpen mode share a
mode) single address table for all configured VLANs; in allClosed mode,
each VLAN has its own unique address table. Standard bridging
rules apply based on the table addresses that are assigned to the
specific VLAN. A router port IP interface requires that you put the
system in allClosed mode.
VID Unique, user-defined integer (VLAN ID) that identifies this VLAN. It
is used by management operations. You can assign or modify a VID
that is associated with a static VLAN; you cannot modify the VID
selected automatically after you define a router port IP interface,
nor can you change the VID of the default VLAN. The default VLAN
requires a VID of 1.
VLAN Aware Whether the VLAN aware mode (tagging mode) is allPorts or
Mode taggedVlanPorts. The default for CoreBuilder 3500 Release
2.0 or later is allPorts; allPorts is also the default as of
(3500 and
CoreBuilder 9000 software Release 3.0. The value
9000 Layer 3)
taggedVlanPorts is a compatibility mode for VLANs configured
prior to CoreBuilder 3500 Release 2.0 and for VLANs configured on
CoreBuilder 9000 Layer 3 modules prior to CoreBuilder 9000
Release 3.0.
