Copy switch configuration file to a TFTP server. It uses Telnet connection (usually enabled by default).
saveconf_3C800.py
saveconf_3C4200G.py
Setting up:
1- You need a TFTP service running somewhere: "apt-get install tftpd-hpa"
2- From script files, change these values:
* username: switch's username
* password: switch's password
* tftp: Host or IP address where TFTP service is installed
3- Execute:
./saveconf_3C3800 192.168.1.250
TFTP: 192.168.1.14
File: sw001.cfg
Backing up...
Backup created succesfully!
