INSTALL

  1. fetchconfig.pl expects a Perl interpreter at /usr/bin/perl.
  2. fetchconfig.pl requires the Net::Telnet module.
  3. Just unpack the fetchconfig tarball at a suitable location. Example:
    [ fetchconfig tarball available at /tmp/fetchconfig-0.0.tar.gz ] 
    cd /usr/local
tar xzf /tmp/fetchconfig-0.0.tar.gz
ln -s fetchconfig-0.0 fetchconfig
    [ fetchconfig is now available under /usr/local/fetchconfig ]

USAGE

  1. Edit the file "device_table.example" according your needs, and save it as "device_table". Example:
    [ fetchconfig available under /usr/local/fetchconfig ] 
    cd /usr/local/fetchconfig
cp device_table.example device_table
vi device_table
  2. Run fetchconfig.pl, as in the following example:
    [ fetchconfig available under /usr/local/fetchconfig ] 
    cd /usr/local/fetchconfig
./fetchconfig.pl -devices=device_table

    The fetchconfig.pl script will scan the "device_table" file, trying to retrieve the configuration for every device, storing configuration files under the "repository".

DEVICE TABLE

The device table assigned with '-device=' switch is a text file which supports two types of lines:

  1. Default options lines assign default options to a device model. The following example adds some default options to the "cisco-ios" model: 

    #default        model           model-default-options
#
default:        cisco-ios       user=backup,pass=fran,enable=jose

  2. Device lines define attributes of every device and optionally assign device-specific options. The following example define a device named "vpn-gw": 

    #model          dev-unique-id   device-host     [device-options]
#
cisco-ios       vpn-gw          192.168.0.1     keep=10,changes_only=1
    The dev-unique-id must be:
    1. an unique identifier across all devices;
    2. a valid filesystem's directory name.

OPTIONS

The CiscoIOS and CiscoCAT modules recognize the following options:

pass A mandatory option, specifies the login password.
user Specifies the login username. It can be omitted for devices not requiring a login username.
enable Mandatory, specifies the enable password.
timeout Mandatory, how long to wait for TELNET responses from devices.
fetch_timeout Optional. If given, will override the timeout value used to fetch all the configuration lines. It is useful for devices which spend several seconds building the configuration.
repository Mandatory, specifies the base directory for saving the configuration files.
keep Mandatory, the maximum number of config files to retain for the device. When this limit is reached, the older files are discarded.
changes_only Optional. If specified as changes_only=1, only new configurations are saved. Otherwise, configurations are saved whenever the script runs; if not defined as changes_only=1, the script might possibly retain multiple identical configuration files.
