Working with
Nonvolatile Data
If you want to transfer NV data from one system to another, save the
system’s NV data and restore it as appropriate. You might also want to save
a certain configuration of the system for your reference and as a backup.
You can also reset system data to its factory-configured values, if necessary.
During a save, the contents of NV memory are written out to a disk file. All
configurable parameters are saved in nonvolatile memory, including:
The file also contains the following information, which is used to resolve any
inconsistencies when NV data is restored:
■ Software version number
■ System ID
■ Date and time of creation
■ Data checksums
■ System name
■ System date and time
■ Passwords
■ Packet filters
■ Ethernet port labels
■ FDDI resources settings
■ Bridge and bridge port settings
■ SNMP community string settings
■ SNMP trap destination configurations
