3Com 4.2.2 manual Vlans in Non-ATM, Virtual LANs

Device Configuration for VLANS in Non-ATM Networks 2-9

Device	Virtual LANs in non-ATM (Fast Ethernet) environments are created by
Configuration for	using Layer 2 encapsulation or Tagging as a means to create broadcast or
VLANS in Non-ATM	flooding domains. Ports that are common to multiple Virtual LANs are
Networks	known as Virtual LAN Trunks (VLT). Switch 1000/3000s and CoreBuilder
	5000 Fast Modules support this feature. VLTs must be configured on the
	switches prior to using the ATM and VLAN application to manipulate the
	VLT-based VLANS. Please refer to the Switch 1000/3000/CoreBuilder
	5000 Fast Module configuration manuals for information on VLT-based
	Virtual LANs.
