NAME

Cisco::CopyConfig - IOS running-config manipulation

SYNOPSIS

use Cisco::CopyConfig ();

see METHODS section below

DESCRIPTION

Cisco::CopyConfig provides methods for manipulating the running-config of devices running IOS via SNMP directed TFTP. This module is essentially a wrapper for Net::SNMP and the CISCO-CONFIG-COPY-MIB-V1SMI.my MIB schema.

PREPERATION

A read-write SNMP community needs to be defined on each device, which allows the setting of parameters to copy or merge a running-config. Below is an example configuration that attempts to restrict read-write access to only the 10.0.1.3 host:

access-list 10 permit host 10.0.1.3
access-list 10 deny any
!
snmp-server tftp-server-list 10
snmp-server view backup ciscoMgmt.96.1.1.1.1 included
snmp-server community 2dcf0eeca916a5 view backup RW 10
end

METHODS

new

Create a new Cisco::CopyConfig object.

$config = Cisco::CopyConfig->new(
           Host  => $ios_device_hostname,
           Comm  => $community_string,
        [ Tmout  => $snmp_timeout_in_seconds, ]
        [ Retry  => $snmp_retries_on_failure, ]
);
copy

Copy the running-config to a TFTP server file. This is a convenient means of backing up a device configuration.

$config->copy($tftp_address, $tftp_file);
merge

Modify or "merge" the current running config with a TFTP server file. This is a conveient means of altering device configuration.

$config->copy($tftp_address, $tftp_file);
error

Return the last error message, if any. It may be more convenient to reference the error variable directly, $config->{err}

$config->error();

EXAMPLE

Using 10.0.1.3 as a TFTP server, the following example copies the running-config of lab-router-a:

    $tftp_a	= '10.0.1.3';
    $tftp_f	= '/tftpboot/lab-router-a.config';
    $host_a	= 'lab-router-a';
    $comm_s	= '2dcf0eeca916a5';
    $config	= Cisco::CopyConfig->new(
		     Host => $host_a,
		     Comm => $comm_s
    );
    if ($config->copy($tftp_a, $tftp_f)) {
      print "${host_a}:running-config -> ${tftp_a}:${tftp_f}\n";
    }
    else {
      print "$config->{err}\n";
    }

PREREQUISITES

This module requires the Net::SNMP and Socket modules.

BUGS

Local file creation and permissions checking are not performed, as TFTP file destinations can be somewhere other than the local system.

Only SNMP v1 and v2 are currently supported in this module. SNMP v3 is on the TODO list.
