ATM supports two types of SPANS connections: SVCs and PVCs.

The filer dynamically assigns SVCs when interoperating with ATM hosts and with switches that support the FORE/IP over SPANS protocols.

You use ATM PVCs to interoperate with ATM hosts and with switches that do not sup- port FORE/IP over SPANS. For example, if you are not using a FORE systems switch, PVCs can connect FORE equipment at each end through
Data ONTAP currently supports only FORE/IP 5.3. The following differences from pre- vious versions are significant:
The name of a SPANS interface in Data ONTAP 5.3 is fan (where n is a number); in previous versions of Data ONTAP it was an. This means that you must change the interface names in your /etc/rc and /etc/hosts files.
In Data ONTAP 5.3, you use the new command atmconfig to configure PVCs.
For further information about the differences between FORE/IP 5.3 and older ver- sions, consult FORE documentation.
