4-2 SmartCell ZX-250 User Guide
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?

The switch must be rebooted for the restore to take effect.
4.2 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)
2 p›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

Determine the address of the IISP device. (For this example, this could be a port address, we use
