If you run the EPICenter client 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 modifythe protocol filters used to filter VLAN traffic
Extreme Networks switches support a maximum of 3000 VLANs.VLANs on Extreme
Networks 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 EPICenter system, a VLAN is defined uniquely by the following:
• 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
abovearethesame.
For a more detailed explanation of VLANs, see the ExtremeWare Software UserGuide.
