If you are using allClosed mode and STP on the system (with multiple
routes to a destination), you can also specify a mode called Ignore STP
mode to disable STP blocking for a specified static VLAN. (Although
each VLAN has its own address table, there can be only one instance
of STP on the system.) See "Ignore STP Mode" for information on this
mode. To disable STP blocking on any port with allOpen or allClosed
VLANs, use the
Console. See Chapter 7 for bridging information.
Your choice of the VLAN mode affects how you manipulate bridge
port addresses (via the Console or the Web). For example:
If you select allClosed mode, you must specify a VLAN interface
index to identify the appropriate bridge address table.
If you select allOpen mode (the default), the entire system has only
one address table, so you can manipulate the bridge port
addresses without specifying a VLAN interface index.
To change your VLAN mode, perform these procedures:
1 Delete all routing interfaces (including router port IP interfaces) that you
have configured on the system. You cannot change the mode if you have
router interfaces defined on the system.
2 Using your configuration tool (for example, the Administration Console
or the Web Management applications), modify the VLAN mode to specify
the new VLAN mode.
When you change the mode, the system deletes all of your existing
configured VLANs and reverts to the default VLAN.
3 Reconfigure your VLANs and redefine your routing interfaces.
For the specific commands for these procedures, see the Command
Reference Guide.
