PVCs are static; for each destination, you must establish (attach the IP layer to) a PVC
explicitly and delete (detach the IP layer from) the PVC explicitly.
For each destination that needs to establish a PVC with the filer, you must establish an
outgoing and an incoming PVC in at least three places:
On the filer
On the destination ATM host
On all interconnecting ATM switches
For each physical ATM interface, the filer creates a FORE/IP interface, called
fa
, at
boot time. The
fa
interface supports FORE/IP on top of SPANS signaling. FORE/IP
allows communication as follows:
Using AAL4 or AAL5 ATM adaptation layer types with no encapsulation
Using a broadcast address resolution protocol (ARP) for SPANS address
resolution
Using direct communication of all hosts on a physical ATM network without the
use of IP routers
Network Appliance does not support FORE/IP load balancing or failover options.

To establish an outgoing FORE/IP PVC on the filer, type the following filer command:
2+%+&'CCCDDD
Table 2 provides descriptions of the variables in the filer command.
hostname
Name or IP address of the remote host.
iface
Name of the ATM interface; this is usually fa
n,
where
n
is a number.
vpi
Virtual path identifier (VPI); this must be 0.
vci
Virtual channel identifier (VCI); this number must have the following
properties:
It must not be in use on your filer.
It must be less than 1024.
It must obey the limits of the destination host and inter-
connecting devices.
