Adding a new Switch

When a new switch starts communicating with OESS, it waits in a pending aproval state.  The pending approval state is to allow an administrator to configure the profile of the device, and verify that the device is suppose to be part of the network.  This prevents unintended devices from becoming a part of the OESS network.  

OpenFlow

The first step in adding a switch to OESS, is to configure the switch so that its controller points to the OESS controller IP address.  Once the connection is established between the switch and the controller the device will appear in the Admin->Discovery section. Clicking the device will open the Device Details panel, and allow you to confirm the device.

To confirm the device will require a few parameters are needed:

The Name of the device specifies the name as it will appear in the OESS UI, in most cases the fully qualified domain name is probably what should be entered.

The Latitude and Longitude fields are used to specify the location of the device.  

The VLAN Range field contains the allowed vlan's used on all trunk interfaces on that node.  This is specifically used when slicing the network or when using hybrid mode.  This range does not affect end interfaces. 

Default Foward LLDP to controller controls whether or not to send the forward LLDP rule to the switch. Without this your switch will not auto discover properly.  Use this only if you know what you are doing.

Default Drop Rule is installed to prevent all flows that are currently not matching from being punted to the controller (as per openflow 1.0 spec).  

Maximum Number of Flow Mods specifies the maximum number of flows that can be installed on a switch.  FWDCTL will prevent any flows over this limit from being installed. (useful when slicing)

Send Bulk Flow Rules specifies if the switch is capable of rate limiting internally or of a Barrier message must be sent between each flow rule.

Once all of these have been selected properly click the "Confirm Device" button at the bottom of the popup to approve the device.

NETCONF

Devices that speak NETCONF must be added manually using the Add MPLS switch button.

Name takes the hostname of the device that will be displayed to the user.

Short name is the name of the device as it appears in show isis adjacencies.

The Latitude and Longitude fields are used to specify the location of the device. 

Vendor, Model, and Software Version defines which NETCONF module is used by OESS to connect to the device.

After entering the above paramerters, click Add MPLS Device.

Dual Stack

It's possible to run both OpenFlow and NETCONF at the same time. Under the Network tab, select your desired OpenFlow device. Under the Update Device dialog box, enable the MPLS Enabled check box. Provide the MPLS related field values as described under the NETCONF section, and then click Update Device.
