Synopsis

This paper describes how to transfer config files between a UNIX system and a Cisco device via a Serial Line using the cu command. See the CU(1) manual page for more detailed description of the command and parameters.

This example will use /dev/cuad0 as the serial line's DSF.

Description

1. Connect to the serial line and login to the Cisco device:

   # cu -l /dev/cuad0

2. To transfer from the Cisco device to the UNIX system:

   1. Change to privileged mode:

      # enable

   2. Disable paging:

      # term len 0

   3. Turn on verbose messages in CU:

      # ~s verbose=true

   4. Initiate the copy (cisco.conf can be whatever name you want to give the file):

      # ~< cisco.conf

   5. Dump the config:

      # wr term

   6. Once the line counter has stopped ticking over, hit CTRL+C twice to break back to IOS. Once done you need to reset the pager:

      # term def len

3. To transfer from the UNIX system to the Cisco device:

   1. Change to privileged mode:

      # enable

   2. Change to configuration mode:

      # conf t

   3. Initiate the copy (cisco.conf is the config file you wish to run):

      # ~> cisco.conf
