VLANS in Non-ATM
Networks
Virtual LANs in non-ATM (Fast Ethernet) environments are created by
using Layer 2 encapsulation or Tagging as a means to create broadcast or
flooding domains. Ports that are common to multiple Virtual LANs are
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.
