Routing between VLANs
3
If you do not want the ports to have dynamic membership, you can add them statically. This
eliminates the need to explicitly exclude the ports that you do not want to participate in a particular
Layer 3 VLAN.
Assigning a different VLAN ID to the default VLAN
When you enable port-based VLANs, all ports in the system are added to the default VLAN. By
default, the default VLAN ID is “VLAN 1”. The default VLAN is not configurable. If you want to use
the VLAN ID “VLAN 1” as a configurable VLAN, you can assign a different VLAN ID to the default
VLAN.
To reassign the default VLAN to a different VLAN ID, enter the following command.
Virtual ADX(config)# default-vlan-id 4094
Syntax: [no] default-vlan-d vlan-id
You must specify a valid VLAN ID that is not already in use. For example, if you have already defined
VLAN 10, do not try to use “10” as the new VLAN ID for the default VLAN. Valid VLAN IDs are
numbers from 1 – 4094.
NOTE
Changing the default VLAN name does not change the properties of the default VLAN. Changing the
name allows you to use the VLAN ID “1” as a configurable VLAN.
NOTE
VLAN ID 4094 is reserved for use by Single STP.
Configuring port-based VLANs
Port-based VLANs allow you to provide separate spanning tree protocol (STP) domains or broadcast
domains on a port-by-port basis.
This section describes how to perform the following tasks for port-based VLANs using the CLI:
• Create a VLAN.
• Delete a VLAN.
• Modify a VLAN.
• Assign a higher priority to the VLAN.
• Change a VLAN’s priority.
Example
Figure 8 shows a simple port-based VLAN configuration using a single Brocade Virtual ADX. All
ports within each VLAN are untagged. One untagged port within each VLAN is used to connect the
devices for Layer 3 connectivity between the two port-based VLANs.
