#Appendix: vSG Configuration

First, login to the CORD head node CLI and go to the /opt/cord_profile directory. To configure the fabric gateway, you will need to edit the file cord-services.yaml. You will see a section that looks like this:

addresses_vsg:
  type: tosca.nodes.AddressPool 
    properties:
      addresses: 10.6.1.128/26 
      gateway_ip: 10.6.1.129 
      gateway_mac: 02:42:0a:06:01:01 

Edit this section so that it reflects the fabric address block assigned to the vSGs, as well as the gateway IP and the MAC address that the vSG should use to reach the Internet.

Once the cord-services.yaml TOSCA file has been edited as described above, push it to XOS by running the following:

cd /opt/cord_profile &&
docker-compose -p rcord exec xos_ui python /opt/xos/tosca/run.py xosadmin@opencord.org &&
/opt/cord_profile/cord-services.yaml 

This step is complete once you see the correct information in the VTN app configuration in XOS and ONOS.

To check that the VTN configuration maintained by XOS:

• Go to the "ONOS apps" page in the CORD GUI:

  • URL: http://<head-node>/xos#/onos/onosapp/
  • Username: xosadmin@opencord.org
  • Password: <content of /opt/cord/build/platform-install/credentials/xosadmin@opencord.org>

• Select VTN_ONOS_app in the table

*Verify that the Backend status is 1

To check that the network configuration has been successfully pushed to the ONOS VTN app and processed by it:

• Log into ONOS from the head node

  • Command: ssh -p 8102 onos@onos-cord
  • Password: "rocks"

• Run the cordvtn-nodes command

• Verify that the information for all nodes is correct

• Verify that the initialization status of all nodes is COMPLETE This will look like the following:

onos> cordvtn-nodes 
	Hostname                      Management IP       Data IP             Data Iface     Br-int                  State 
	sturdy-baseball               10.1.0.14/24        10.6.1.2/24         fabric         of:0000525400d7cf3c     COMPLETE 
	Total 1 nodes 

• Run the netcfg command. Verify that the updated gateway information is present under publicGateways:

"publicGateways" : [ {
               "gatewayIp" : "10.6.1.193",
               "gatewayMac" : "02:42:0a:06:01:01"
             }, {
               "gatewayIp" : "10.6.1.129",
               "gatewayMac" : "02:42:0a:06:01:01"
             } ],
