Connectivity Guide

● The OS10 VTEP sends MAC addresses addition or deletion events at the VXLAN access port to the NSX controller through
OVSDB protocol. The controller then propagates the information to the other VTEPs so that the VTEPs program their
forwarding tables accordingly.
Steps to configure controller-provisioned VXLAN
To configure the NSX controller, follow these steps on each OS10 VTEP:
1. Assign an IPv4 address to a Loopback interface.
2. Create an NVE instance and configure the Loopback interface as NVE source interface.
3. Specify the NSX controller reachability information
4. Assign interfaces to be managed by the controller.
5. (Optional) Enable BFD in the NSX and the VTEP.
For more information about assigning an IPv4 address to a Loopback interface and configuring the Loopback interface as NVE
source interface, see the Configure source IP address on VTEP section in the OS10 Enterprise Edition User Guide. The rest of
the configurations are explained below.
Specify the controller reachability information
In OS10 VTEP, the controller configuration command initializes a connection to an OVSDB-based controller.
OS10 supports only one controller connection at a time.
NOTE: Currently, the only supported OVSDB-based controller is NSX.
To configure an OVSDB controller on the OS10 VTEP:
1. Enable VXLAN in CONFIGURATION mode.
OS10(config)# nve
2. Changes the mode to CONFIGURATION-NVE-OVSDB from where you can configure the controller parameters.
OS10(config-nve)# controller ovsdb
3. Specify the IP address, OVSDB controller port, and SSL as a secure connection protocol between the OS10 VTEP and the
controller in CONFIGURATION-NVE-OVSDB mode.
OS10(config-nve-ovsdb)# ip ip-address port port-number ssl
The range of port-numberis from 0 to 65535. Configure the port-number as 6640 and the connection type as SSL.
4. (Optional) Specify a time interval, in milliseconds (ms). This is the duration the switch waits between the connection
attempts to the controller.
OS10(config-nve-ovsdb)# max-backoff interval
The range is from 1000 to 180,000 ms. The default is 8000 ms.
OS10# configure terminal
OS10(config)# nve
OS10(config-nve)# controller ovsdb
OS10(config-nve-ovsdb)# ip 10.11.66.110 port 6640 ssl
Assign interfaces to be managed by the controller
In a VTEP, explicitly assign interfaces for an OVSDB controller to manage.
Before you assign the interface, consider the following:
● The interface must be in Switchport Trunk mode.
● The interface must not be a member of any VLAN
● The interface must not be a member of a port-channel
When the above conditions are not met when assigning the interfaces to be managed by the controller, the system returns error
messages.
When the interface is assigned, you cannot:
● remove the interface from Switchport Trunk mode
