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
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.
NOTE
Protocol-based VLANS are supported only on the “i” series and Summit 400 series switches.
• MAC address—MAC-based VLANs allow physical ports to be mapped to a VLAN based on the
source MAC address learned in the FDB.
• A combination of these criteria.
