7-2 EXTREMEWARE ENTERPRISE MANAGER INSTALLATION AND USER GUIDE
USING THE VLAN MANAGER
The VLAN Manager is an enterprise-wide application that manages all aspects of
VLANs on Extreme devices. If you run the Enterprise Manager with Administrator or
Manager access, you can:
• Create and delete VLANs
• Add or remove ports from existing VLANs
• Modify a VLAN’s IP address
• Enable/disable IP Forwarding
• Create and modify the protocol filters used to filter VLAN traffic
Extreme switches support a maximum of 256 VLANs. VLANs on Extreme switches can
be created according to the following criteria:
• Physical port
• 802.1Q tag
• Protocol sensitivity using Ethernet, LLC SAP, or LLC/SNAP Ethernet protocol filters
• A combination of these criteria
In the Enterprise Manager, a VLAN is defined uniquely by its
• Name
• 802.1Q tag (if defined)
• Protocol filters applied to the VLAN
As a result, multiple switches are shown as members of the same VLAN whenever all
the above are the same.
For a more detailed explanation of VLANs, see the chapter “Virtual LANs (VLANs)” in
the Summit Switch Installation and User Guide.
DISPLAYING VLANS
When you click the VLAN icon in the ExtremeWare Enterprise Manager Navigation
Toolbar, the VLAN Manager window is displayed, as shown in Figure 7-1.
