SALT

Salt is a different approach to infrastructure management, founded on the idea that high-speed communication with large numbers of systems can open new capabilities. This approach makes Salt a powerful multitasking system that can solve many specific problems in an infrastructure.

The backbone of Salt is the remote execution engine, which creates a high-speed, secure and bi-directional communication net for groups of systems. On top of this communication system, Salt provides an extremely fast, flexible, and easy-to-use configuration management system called Salt States.

For a list of Salt’s Napalm supported modules, please refer to the NAPALM-Onyx github repository.

  3. Create the top.sls file inside this directory.

    Per each switch, insert the following information:

    • DEVICE_ID

    • DEVICE_SLS_FILENAME

  4. Create a new file: [DEVICE_SLS_FILENAME].sls
    Insert the following information into the above file:

    Copy
    Copied!

  5. Restart Salt on the server in order to use the new configuration

    Copy
    Copied!
                

    systemctl stop salt-minion systemctl stop salt-master systemctl stop salt-proxy@<switch_name> systemctl start salt-master systemctl start salt-minion systemctl start salt-proxy@<switch_name>

The following Salt command can be used:

  1. Check if the switch is connected to the server running the Salt master:

    Copy
    Copied!
                

    salt onyx1 net.connected

  2. Run any command on the switch using net.cli (example: using “show version”):

    Copy
    Copied!
                

    salt onyx1 net.arp

  5. Get switch information (uptime, vendor, os-version, etc):

    Copy
    Copied!
                

    salt onyx1 net.facts
