Field Description
Index Module-assigned index number that identifies a VLAN of the
identified origin. Statistics appear in the display for the VLAN that
you specify.
Name Character string of from
0
through
32
bytes that identifies the
VLAN. The default VLAN always uses the name
Default
.
Origin For all Layer 2 Switching Modules, the VLAN origin is always
static
, which indicates that the user created the VLAN. For
Multilayer Switching Modules, the origin 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
module 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.
The list of ports includes the module’s front-panel ports and the
appropriate backplane ports.
Type
(VLAN mode) Either
allOpen
or
allClosed
. VLANs in allOpen mode share a
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
module in allClosed mode.
