SDX-L2 dependencies

SDX-L2 implements its own ARP/NDP handler, it is important to disable the ONOS ARP/NDP handler.

SDX-L2 installation

  • Compile the project:

      mci
    

    or to skip unit tests:

      mci -Dmaven.test.skip=true
    
  • Install in your ONOS deployment:

      onos-app $OC1 install target/onos-app-sdx-l2-1.7.0-SNAPSHOT.oar
    

SDX-L2 CLI commands

General

  • Create a named SDX:

      sdxl2-add $sdxname
    
  • Delete a named SDX:

      sdxl2-remove $sdxname
    
  • List all the active SDXs:

      sdxl2-list
    

Connection Points (CP)

  • Create a named SDX-L2 CP:

      sdxl2cp-add [-ce_mac $mac] $sdxname $connectionpoint $sdxcpname [$vlans]
    

    where $vlans can define:

    • explicit VLANs, ranges or a combination of both: 5,10-15
    • all port: -1 (or just ignore)

note that CPs must have same number of VLANs in order to establish a VC

  • Remove a named SDX-L2 CP:

      sdxl2cp-remove $sdxcpname
    
  • Get the information of an SDX-L2 CP:

      sdxl2cp $sdxcpname
    
  • List all active SDX-L2 CPs or all active SDX CPs related to an SDX:

      sdxl2cp-list [$sdxname]
    

Virtual Circuits (VC)

  • Create a VC between two CPs:

      sdxl2vc-add $sdxname $sdxcp1 $sdxcp2
    
  • Remove a named VC:

      sdxl2vc-remove $sdxcname
    
  • Get the information of a L2 VC:

      sdxl2vc $sdxvcname
    
  • List all active L2 VCs or all L2 VCs related to an SDX:

      sdxl2vc-list [$sdxname]
    

SDX-L2 usage examples

  • Create a named SDX-L2:

      onos> sdxl2:sdxl2-add SDXL2Test
      onos> sdxl2:sdxl2-list
    
      SDXL2
      --------------
      SDXL2Test
    
  • Create two CPs and list brief and detailed info:

    where the connection points are the IDs of the devices provided through the 'edge-ports' ONOS CLI command

      onos> sdxl2:sdxl2cp-add -ce_mac 00:00:00:00:00:01 SDXL2Test of:0000000000000003/2 Sw3P2 5,15-17
      onos> sdxl2:sdxl2cp-add -ce_mac 00:00:00:00:00:02 SDXL2Test of:0000000000000002/1 Sw2P1 6,19-21
    
      onos> sdxl2:sdxl2cp-list

  • Create a VC connecting the two CPs and get its details:

      onos> sdxl2:sdxl2vc-add SDXL2Test Sw2P1 Sw3P2
      onos> sdxl2:sdxl2vc-list

  • Remove VC and check it exists no longer:

      onos> sdxl2:sdxl2vc-remove SDXL2Test:Sw2P1-Sw3P2
      onos> sdxl2:sdxl2vc-list
    
  • Remove CPs and check they exist no longer:

      onos> sdxl2:sdxl2cp-remove Sw2P1
      onos> sdxl2:sdxl2cp-remove Sw3P2
      onos> sdxl2:sdxl2cp-list
    
  • Remove SDX-L2 and check it does not exist anymore:

      onos> sdxl2:sdxl2-list SDXL2Test
      onos> sdxl2:sdxl2-list
    

Tips

  • You should define a topology and point to your local/remote ONOS instance. Some examples:

    • Mininet sudo mn --controller remote,ip=127.0.0.1 --tree,2,2
    • ONOS/Mininet onos-start-network
  • You may check the nodes available at ONOS from Mininet:

      onos> edge-ports
