VLAN Commands
This chapter describes commands for:
• Creating and deleting VLANs and performing basic VLAN configuration
• Defining protocol filters for use with VLANs
• Creating and deleting VMANs and performing basic VMAN configuration
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.
