VLAN overview
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
• Change a VLAN priority
• Enable or disable STP on the VLAN
Example 1—Simple port-based VLAN configuration
Figure 72 shows a simple port-based VLAN configuration using a single Brocade Layer 2 switch. All
ports within each VLAN are untagged. One untagged port within each VLAN is used to connect the
Layer 2 switch to a Layer 3 switch (in this example, a FSX) for Layer 3 connectivity between the two
port-based VLANs.
FIGURE 72 Port-based VLANs 222 and 333
When you add a port-based VLAN,
the device removes all the ports in the
new VLAN from DEFAULT-VLAN.
