For CoreBuilder 9000: Applies to Layer 3 switching modules only.

Creates a VLAN on the CoreBuilder 3500 system or a CoreBuilder 9000 Layer 3 module. When you explicitly configure a VLAN on the system, you assign information such as a VLAN ID (VID), a set of bridge ports, and, optionally, a protocol type and IEEE 802.1Q tagging.

For details about this command on the SuperStack II Switch 3900, the Switch 9300, the CoreBuilder 9400, and CoreBuilder 9000 Layer 2 modules, see “bridge vlan define (3900/9300/9400/ 9000 Layer 2)” next.

Important Considerations

■If you have previously defined your IP VLANs with Layer 3 address information (that is, network-based VLANs), you can redefine your IP VLANs without Layer 3 address information. To define multiple IP interfaces per IP VLAN, use the ip interface define command. (See Chapter 16.)

■The VLAN that you create with this command is a static VLAN. To establish routing between static IP VLANs, define your IP VLANs and then use the ip interface define command to define an IP routing interface. As of Release 3.0, you can also specify the interface type vlan to create one or more IP routing interfaces for a static IP VLAN.

■If you have a router port IP interface on the system, you cannot specify the port that belongs to the router port IP interface when you explicitly define an IP VLAN (or a VLAN that includes the IP protocol). A router port IP interface is an alternative to static VLANs and allows routing versus bridging. You create a router port IP interface by entering the ip interface define command with the interface type port and a single bridge port. A router port IP interface requires allClosed mode. See Chapter 16 for more information.
