You can use ATM in two ways on a Dell PowerVault 720N, 740N, or 760N filer (hereaf- ter referred to as a filer):
ATM local area network emulation (LANE), which provides the services of an Ethernet LAN (ELAN) to
FORE/IP over Simple Protocol for ATM Network Signaling (SPANS) with perma- nent virtual circuits (PVCs)
The filer can simultaneously support FORE/IP over SPANS as well as LANE over user network interface (UNI) 3.0 or 3.1 on the same physical interface.
Many organizations use a LAN for their internal data communications needs. Exam- ples of these LANs include Ethernet/IEEE 802.3 and IEEE 802.5 (Token Ring). However, LANs typically offer a connectionless service, while ATM is always
NOTE: To use
In addition to the issue of
The shared medium approach of LANs make them ideal for broadcast and multi- cast messages.
The media access control (MAC) addresses used to identify a network interface are typically based on the manufacturer’s serial numbers.
This means that the address is constant, independent of the network to which the interface is connected.
LANE is an ATM service that offers the following services:
The capability to run
The capability for ATM networks to be interconnected with conventional LANs by means of existing bridging methods.
This permits application programs running on
The capability of running more than one ELAN on the same ATM network, with each ELAN independent of the others.
This means that users cannot communicate between ELANs without the appro- priate routing or bridging methods.
