Cisco_config.rb

What is it?

This library allows one to access Cisco routers and switches configuration via SNMP. Using SNMP access it triggers a command on the device that will upload the configuration file to the TFTP server specified.

How?

require 'CiscoConfig'

cisco = CiscoConfig.new(:host => 'router0.example.org', :comm => 'secretcommunity')
rnd = cisco.copy_from_cisco('tftpserver.example.com', 'config/cisco0.conf')

This snipplet will tell the device accessible via 'router0.example.com' to upload it's configuration to the TFTP sever at 'tftpserver.example.com'. The second argument of the copy_from_cisco method is the actual filename to save the configuration to. You should also specifiy the SNMP community configured on your device via the :comm keyword argument of the constructor.

Interface

The CiscoConfig class provides the following methods:

  • new(config = {}). The constructor accepts the Hash table containing the device access configuration. Specifically, the following options are supported right now:

    • :host -- the hostname of the device
    • :port -- the device SNMP port
    • :comm -- SNMP community name.

  • copy_from_cisco(tftp_host, tftp_file). This method triggers the device upload command. The configuration file will be uploaded to the host identified by tftp_host under the tftp_file filename. The destination directory of tftp_file should already exist. The method will return numerical ID of the command, which can be used to check for the status later.

  • get_status(id, timeout = 10). This method returns the status of the previous command identified by 'id'. It will wait up to timeout seconds for the operation to complete if it is in progress.
