ATM Routing
  Switch Administration
Once you enter the 
backup
 command, the switch stores the IP address of the TFTP server, the path, and the backup file 
name. The next time the 
backup
 or 
restore
 commands are entered, these values are presented as the default IP address 
and path. For example, when the 
restore
 command is entered, the following appears:
SmartCell ZX# restore switch
ServerIP(90.1.1.100) :
Path(/back_dir/config-1) :
SmartCell ZX # 
Backup file is valid.
Restoring a backup file will completely replace any data stored in the flash. 
Are you sure this is what you want to do? 
Confirm(y/n)?: y
SmartCell ZX #

The switch must be rebooted for the restore to take effect.

ATM ROUTING
The SmartCell ZX-250 default routing protocol is PNNI version 1.0. PNNI provides automatic and dynamic 
connectivity among all PNNI nodes within the same peer group. For purposes of interoperability, however, the 
SmartCell ZX-250 also supports these additional ATM routing protocols:
U
IISP — Use to connect with devices that do not support PNNI
U
UNI — Use to connect end stations (also to connect devices whose implementation of ILMI is 
incompatible with the SmartCell ZX-250)
2p›F
Both IISP and UNI routes are created and modified using the
 ATMRoute
 command. 
The proper route type is determined by the SmartCell ZX-250 through interface 
signaling information.
4.2.1
Creating an IISP Route
Use the 
add ATMRoute
 command to create an IISP route that links the SmartCell ZX-250 to a device that supports only 
IISP routing. For example,
s•
Physically connect port 
b2
 of the SmartCell ZX-250 to the IISP device.
¢•
Enter 
show NetPrefix
 to determine the net prefix of port 
b2
 on the SmartCell ZX-250:
SmartCell ZX # show netprefix b2
Port      NetPrefix
==============================================================================
B2        39:00:00:00:00:00:00:00:00:00:14:41:80
SmartCell ZX #
••
Determine the address of the IISP device. (For this example, this could be a port address, we use 
52:00:00:00:00:00:00:00:00:00:14:51:80)
