If you would like to contribute to the development of OpenStack, you must
follow the steps in this page:
http://docs.openstack.org/infra/manual/developers.html
If you already have a good understanding of how the system works and your
OpenStack accounts are set up, you can skip to the development workflow
section of this documentation to learn how changes to OpenStack should be
submitted for review via the Gerrit tool:
http://docs.openstack.org/infra/manual/developers.html#development-workflow
Pull requests submitted through GitHub will be ignored.
Bugs should be filed on Launchpad, not GitHub:

the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

##### OpenStack OmniSwitch Network Plug-in Configuration Parameters #####
[ml2_ale_omniswitch]
# This section provides details about the OmniSwitch devices and other configuration options.
# OMNI_EDGE_DEVICES:
# The list of OmniSwitch edge devices. The format of the 'omni_edge_devices' is as follows:
# omni_edge_devices = <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<compute-interfaces>:<core-interfaces>,
# <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<compute-interfaces>:<core-interfaces>,
# ...
# ...
# <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<compute-interfaces>:<core-interfaces>
#
# where, 'switch-ip' is the management ip address of the edge switch.
# 'switch-type' is the type of the switch;
# possible values are: OS6900, OS10K, OS6850E, OS6855, OS6450, OS9000 or OS6860.
# 'user-name' is the user login for the switch.
# 'password' is the password credentials for the above user-name.
# 'command-prompt' is the command prompt string set for the switch.
# 'access-method' is the mechanism to be used to access the switch;
# possible values are: REST or TELNET depending on device support.
# (Note: see SWITCH_ACCESS_METHOD for more.)
# 'compute-interfaces' are the interfaces on the edge switch connected to 'compute' nodes.
# 'core-interfaces' are the interfaces on the edge switch connected to the core switch of the network.
#
# Note: Device entries are separated by comma (,) and many devices may be added to the list.
# Interfaces are separated by space (' ') and many interfaces may be added to the list.
# Interfaces should be in the format corresponding to the platform used:
# Possible values for OS6900 and OS10K: slot/port, chassis/slot/port or linkagg_id.
# For example,
# 1/2 if it is a standalone unit, represents slot/port
# 1/2/3 if it is a VC, represents chassis/slot/port
# 1 if it is a linkagg, represents linkagg_id
# Possible values for OS6850E, OS6855, OS9000 and OS6450: slot/port or linkagg_id.
# For example,
# 1/2 represents slot/port
# 1 if it is a linkagg, represents linkagg_id
# Possible values for OS6860: chassis/slot/port or linkagg_id.
# For example,
# 1/2/3 if it is a standalone unit or VC, represents chassis/slot/port
# 1 if it is a linkagg, represents linkagg_id
#
# Each item in the entry is separated by colon (:).
# For user-name, password and command-prompt the default values 'admin', 'switch', '->' will be
# used if empty but still separated by colon (:).
#
# For example,
# omni_edge_devices = 10.255.222.10:OS6900:admin:switch:->:TELNET:1/1 1/2:1/20 1/21,
# 10.255.222.10:OS6850E:jhonc:alcatel123:Campus-Edge1->:TELNET:1/1 1/2:1/20 1/21,
# 10.255.222.10:OS10K: : : :REST:1/1 1/2:1/20 1/21
#omni_edge_devices = 10.255.222.10:OS6900: : : :TELNET:1/3:1/19,
# 10.255.222.12:OS6900: : : :TELNET:1/2:1/20
omni_edge_devices = 10.255.222.10:OS6900: : : :TELNET::1/19,
10.255.222.12:OS6900: : : :TELNET:1/2:1/20
# OMNI_CORE_DEVICES:
# The list of OmniSwitch core devices. The format of the 'omni_core_devices' is as follows:
# omni_core_devices = <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<interfaces>,
# <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<interfaces>,
# ...
# ...
# <switch-ip>:<switch-type>:<user-name>:<password>:<command-prompt>:<access-method>:<interfaces>
#
# Note: The description and format of the individual items are same as edge devices except for 'interfaces'.
# Here, 'interfaces' are the interfaces on the core switch connected to edge switches
# and/or other core switches.
#
# For example,
# omni_core_devices = 10.255.222.20:OS10K:admin:switch:->:REST:1/20 1/21,
# 10.255.222.30:OS6850E:jhonc:alcatel123:Campus-Edge1->:TELNET:1/20 1/21,
# 10.255.222.40:OS9000: : : :REST:1/1 1/2
omni_core_devices = 10.255.222.11:OS6900: : : :TELNET:1/19 1/20
# DHCP_SERVER_INTERFACE:
# The edge switch's ip address and the interface connected to the network node of the OpenStack setup
# (the dhcp-server is running on the network node).
# The format of the 'dhcp_server_interface' is the same as a core device, but with only one entry.
# For example,
# dhcp_server_interface = 10.255.222.20:OS10K:admin:switch:->:TELNET:1/20 1/21
dhcp_server_interface = 10.255.222.10:OS6900: : : :TELNET:1/3
# SWITCH_SAVE_CONFIG_INTERVAL:
# This is used to specify how often (in seconds) the config changes in the switches are to be saved.
# The valid range is 600 - 1800 seconds. If value is out of range, it will default to 600 seconds.
switch_save_config_interval = 600

class OmniSwitchRestfulDriver(object):
"""Name: OmniSwitchRestfulDriver.
Description: OmniSwitch device driver to communicate with OS6900 and OS10K devices which support
RESTful interface.
Details: It is used by OmniSwitchDevicePluginV2 to perform the necessary configuration on the physical
switches as response to OpenStack networking APIs. This driver is used only for OS6900, OS10K
and OS6860 devices which support RESTful APIs to configure them. This driver requires the following
minimum version of AOS SW to be running on these devices...
OS10K : 732-R01-GA
OS6900 : 733-R01-GA
OS6860 : 811-R01-GA
It uses the "consumer.py" library provided as a reference implementation from the AOS/OmniSwitch
point of view. No changes is made as part of OmniSwitch plug-in or driver development. For
latest version of consumer.py, refer "//depot/7.3.3.R01/sw/management/web/consumer/consumer.py".
For any issues/bugs with the library, please contact AOS 7x WebService module owner
(Chris Ravanscoft).
