Using the VLAN Manager

This chapter describes how to use the VLAN Manager for:
• Viewing enterprise-wide, tagged and untagged VLAN information for Extreme (Summit and
BlackDiamond) switches managed by the EPICenter software
• Adding new tagged or untagged VLANs to Extreme devices, adding ports to those VLANs, and
modifying IP addresses
• Deleting VLANs
• Modifying VLANs
• Adding and deleting protocol filters

Overview of Virtual LANs

A Virtual LAN is a group of location- and topology-independent devices that communicate as if they
were on the same physical local area network (LAN). Extreme Networks switches have a VLAN feature
that enables you to construct broadcast domains without being restricted by physical connections.
The VLAN Manager creates and manages VLAN for Extreme Networks devices only. It does not handle
other third-party devices, even though third-party devices can be managed through the Inventory
Manager.
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 modify the protocol filters used to filter VLAN traffic
Extreme Networks switches can 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
