#!/usr/bin/expect -f
#
# Filename: /usr/local/etc/backup-symbolswitches.exp
#
# Purpose:  Expect script designed to telnet into Symbol Wireless LAN switch
#           and execute the CLI commands to backup the switch configuration
#           to the TFTP server.
#
# Languate: Expect

# Author:   Michael McNamara

# Date:     June 1, 2005
#
# Version:  1.0
#
# Changes:
#           June 8, 2005 (M.McNamara)
#           o add documentation and ARGV command line checks
#
# Notes:    supported Motorola(formerly Symbol) software versions and hardware
#           -  Symbol 5000 Wireless LAN Switch (v1.4.3-x)
#           -  Symbol 5100 Wireless LAN Switch (v1.4.3-x)
#
#           Motorola has recently release v3.x software for the WS5100. This
#           new version of software is completely different than the v2.x 
#           software from previous releases. I'm using a different set of
#           routines to backup those (v3.x) switches via SNMP commands (still
#           utilizing a TFTP server as the destination).
