# ICX Switch Configuration Script with Posh-SSH
# This script is designed to extract IP Addresses from switches.txt, SSH into the switch 
# with the provided credentials (brocade, brocade), and backup the configuration of the switches. 
# The output will be saved in the configs directory and the file will be named
# for the switch IP Address and then exit the session. The directory must exist to save the files.
#

# Enter user credentials into the script
