Getting Started — ATM
As stated earlier, this release provides Ethernet to ATM connectivity
through ATM Permanent Virtual Circuits (PVCs). This means that each
switch
must have a PVC link between itself and any other
switch
. Figure 6
shows a typical ATM PVC network topology.
This configuration allows any device connected to any
switch
to communicate
with any other device — assuming that each device is in the same Emulated
LAN. Note that it is not necessary for every unit to be interconnected to
every other one. Only units that have devices which need to communicate
need to be connected.
