12 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 local area network (VLAN) is a group of location- and topology-independent devices that
communicate as if they were on the same physical 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 VLANs 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
●
Create and modify the protocol filters used to filter VLAN traffic
●
Enable/disable IP Forwarding on a switch (for the entire switch)
Extreme Networks switches can support a maximum of 4000 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
