    Manage switches in a Dell Chassis.

    name
        The switch designation (e.g. switch-1, switch-2)

    ip
        The Static IP Address of the switch

    netmask
        The netmask for the static IP

    gateway
        The gateway for the static IP

    dhcp
        True: Enable DHCP
        False: Do not change DHCP setup
        (disabling DHCP is automatic when a static IP is set)

    password
        The access (root) password for the switch

    snmp
        The SNMP community string for the switch

    Example:

    .. code-block:: yaml
