Cisco Cisco NetFlow Generation Appliance (NGA) 3340 インストールガイド

Having a backup configuration file can save you time and frustration if your NGA appliance should 
suffer a hard disk failure that requires you to reformat or repartition your hard disk drives. This 
procedure does not back up the capture files and the monitoring data.

To back up your current configuration, use the NGA CLI config upload command like the following:

For example: 

In NGA 3340, besides ftp, secure transfer protocol such as sftp, scp and https is also supported. You can 
run config upload ? to get the latest help info and example.

The config upload command sends a copy of the NGA running configuration to the destination you 
specify. The copy of your configuration is stored in a back-up configuration file with an ending suffix of 
.config as in NGA_host-nga-1.1-1.config. The destination address should be a valid server name and 
directory path where you have read and write permissions.

If you have stored your NGA configuration file at a remote server location that you can access using FTP 
or HTTP (see 

), you can restore your NGA configuration file 

after a system recovery or upgrade. This, however, is optional.

Use the config network command to restore your previous NGA configuration, as in the following: 

For example: 

In NGA 3340, besides ftp, secure transfer protocol such as sftp, scp and https is also supported. You can 
run config upload ? to get the latest help info and example.

To upgrade the software for a Cisco NetFlow Generation Appliance:

Download the NGA application software for the Cisco NetFlow Generation Appliance from the 
Cisco.com at the following URL: 

Look for a file that begins with nfa-app, as in nfa-app-x86_64.x-x-x.bin.gz

(where x-x-x is the NGA 

software release number). The file will be described as the NGA Application Image.

Store the NGA application software on the same server where you archived your NGA configuration.
