switchs

This tool sets up the switches used for the InsaLan tournament.

Configuration

The tool needs two JSON files :

• switchs_file: contains the list of all the switches to configure and the configuration chosen for each switch
• configs_file: describes the configurations to apply (which ports are tagged/untagged and on which VLANs)

Note

All configuration files must be in the /config directory.

How to use it?

The main entrypoint is switchs.py.

usage: switchs.py [-h] [--switch NUMBER] [--new-password PASSWORD] switchs_file configs_file access_password

Configure switches automatically

positional arguments:
  switchs_file          JSON file containing the list of switches
  configs_file          JSON file containing the list of configurations
  access_password       Password to access the switches

options:
  -h, --help            show this help message and exit
  --switch NUMBER, -s NUMBER
                        Switch to configure (by number)
  --new-password PASSWORD, -p PASSWORD
                        New password for the switches (must be at least 8 characters long)

For example, if you want to configure the switch number 24 (with IP address 172.16.1.124), you would run the following command:

python3 switchs.py config/switches.json config/config.json password -s 24

Run it without --switch to be prompted for each switch in the list.

How it works?

This script detects the model of each switch from the switch file and then automatically calls the right configuration script depending on the model (enterasys24p, enterasys48p, procurve24p...).

enterasys24p_config connects via telnet and sends all configuration commands directly through the virtual terminal.
enterasys48p_config, brocade48p_config and procurve24p_config generate a configuration file locally, place it in the tftp folder, and then connect to the switch via telnet and simply ask the switch to download the configuration file from this very machine with TFTP.
We do that because telnet is unstable and the "basic" way (the enterasys24p_config way) often crashed on 48p.
