Configuring the Cisco ATA Using a TFTP Server
This section contains the following topics:
• Configuration Files that the cfgfmt Tool Creates, page 3-13
• cfgfmt Tool Syntax and Examples, page 3-14
Configuration Files that the cfgfmt Tool Creates
The number of output binary configuration files that the Cisco ATA produces is dependent on two
factors:
• Which encryption key parameter is used—EncryptKey or EncryptKeyEx
• The total size of the binary output
Table 3-5 shows the names of the binary files that can be generated. One, two or four files can be
generated.
Note <macaddress> in Table 3-5 is the MAC address of the Cisco ATA.
Note If you are creating an atadefault configuration file, the generated binary file name will be
atadefault.cfg.x if you encrypt the text file with the EncryptKeyEx parameter; the binary file name will
be atadefault.cfg if you do not use the EncryptKeyEx parameter to encrypt the text file. For information
on creating an atadefault configuration file, see the “atadefault.cfg Configuration File” section on
page 3-17.
Note Place all generated binary configuration files onto the TFTP server.
