==================
Compatible Devices
==================

The following devices are compatible with this plugin:

.. netmiko-device-commands::
  :output-type: all-devices

This Mechanism Driver architecture allows easily to add more devices
of any type.

::

  OpenStack Neutron v2.0 => ML2 plugin => Generic Mechanism Driver => Device plugin

These device plugins use `Netmiko <https://github.com/ktbyers/netmiko>`_
library, which in turn uses `Paramiko` library to access and configure
the switches via the SSH protocol.

Cisco Nexus (netmiko_cisco_nxos)
--------------------------------

Known working firmware versions: 10.3.7

Notes:

 * Default state for switches is well suited for networking-generic-switch
   as long as SSH is utilized *and* the underlying role provided to the
   account permits configuration of switchports.
 * Pre-configuration of upstream network trunk ports to the neutron networking
   nodes is advisable, however the ``ngs_trunk_ports`` setting should be
   suitable for most users as well.
 * Use of an "enable" secret through the ``secret`` configuration option has
   not been tested.
 * Security group limitations:
    * Only ingress rules allowed
    * Only IPv4 rules are implemented
    * Supports rules for protocols: tcp, udp, icmp

Dell Force10 OS9 (netmiko_dell_force10)
---------------------------------------

Known working firmware versions: 9.13.0.0

Notes:

 * Dell Force10 Simulator for 9.13.0 lacks the ability to set a switchport
   mode to trunk, which prevents automated or even semi-automated testing.
   That being said, creating VLANs and tagging/untagging works as expected.
 * Uplink switchports to the rest of the network fabric must be configured in
   advance if the ``ngs_trunk_ports`` switch device level configuration
   option is *not* utilized.
 * Use of SSH is expected and must be configured on the remote switch.
 * Set each port to "switchport" to enable L2 switchport mode.
 * Use of an "enable" secret through the switch level configuration option
   ``secret`` was the tested path. Depending on precise switch configuration
   and access control modeling, it may be possible to use without an enable
   secret, but that has not been tested.
 * Security groups not yet implemented

Known Issues:

 * `bug 2100641 <https://bugs.launchpad.net/ironic/+bug/2100641>`_ is
   alieviated by setting a port to "switchport" *before* attempting to utilize
   networking-generic-switch.

Dell Force10 OS10 (netmiko_dell_os10)
-------------------------------------

Known working firmware version: 10.6.0.2.74

Notes:

 * Uplink switchports may need to be configured as Trunk ports prior to the
   use of networking-generic-switch through a "switchport mode trunk" command.
   Further specific trunk configuration may be necessary, however NGS can
   leverage the ``ngs_trunk_ports`` configuration option and does appropriately
   tag switchports as permitted when creating/deleting attachments.
 * Password authentication for networking-generic-switch needs to be setup in
   advance, specifically "ip ssh server enable" and
   "ip ssh server password-authentication" commands.
 * This driver was tested *without* the use of an enable secret to
   permit a higher level of configuration access within the Switch.
 * Security groups not yet implemented

Sonic - Community Distribution (netmiko_sonic)
----------------------------------------------

Known working firmware version: master branch - March 2025

Notes:

 * The driver expects to be able to SSH into the switch running
   SONiC, execute sudo, and then execute configuration commands.
 * Ports *must* be in Layer-2 mode. As such,
   ``sudo config interface ip remove $INTERFACE $IP_ADDRESS/$CIDR``
   and ``sudo config switchport mode access $INTERFACE`` commands
   may be required.
 * Uplink switch ports should be configured in advance with the
   ``sudo config switchport mode trunk $INTERFACE`` command.
   Testing for the configuration utilized this advanced state
   configuration of the trunk uplink ports with the ``ngs_trunk_ports``
   configuration option for Networking-Generic-Switch.
 * Security groups not yet implemented
