ExtremeWare Software 7.3.0 Command Reference Guide 313
5 VLAN Commands
This chapter describes the following commands:
• Commands for creating and deleting VLANs and performing basic VLAN configuration
• Commands for defining protocol filters for use with VLANs
• Commands for enabling or disabling the use of Generic VLAN Registration Protocol (GVRP)
information on a switch and its ports
VLANs can be created according to the following criteria:
• Physical port—A port-based VLAN consists of a group of one or more ports on the switch. A port
can be a member of only one port-based VLAN, and is by default a member of the VLAN named
“Default.”
• 802.1Q tag—Tagging is most commonly used to create VLANs that span switches.
• Ethernet, LLC SAP, or LLC/SNAP Ethernet protocol type—Protocol-based VLANs are most often
used in situations where network segments contain hosts running multiple protocols.
• A combination of these criteria.
The Generic VLAN Registration Protocol (GVRP) allows switches to learn some VLAN information
automatically instead of requiring manual configuration in each switch. A VLAN can provide GVRP
information about its VLANs and accept information about VLANs from other GVRP-enabled switches.
Depending on the circumstances, information learned in this manner may cause ports to be added to
VLANs already existing on the switch, or may cause new tagged VLANs to be created automatically.
NOTE
GVRP is not supported in ExtremeWare versions 6.1 or later.
