======XRN CONFIGURATION PROCESS======


**Configure Switch A:**
  [SW5500]change unit-id 1 to 1
  [SW5500]set unit 1 name unit1
  [SW5500]sysname hello

**Configure Switch B:**
  [SW5500]change unit-id 1 to auto-numbering
  [SW5500}set unit 1 name unit2
  [SW5500]sysname hello

**Configure Switch C:**
  [SW5500]change unit-id 1 to auto-numbering
  [SW5500}set unit 1 name unit3
  [SW5500]sysname hello
  
**Configure Switch D:**
  [SW5500]change unit-id 1 to auto-numbering
  [SW5500}set unit 1 name unit
  [[SW5500]sysname hello
  

----------------------


**XRN enable:**

  [XRN]fabric-port ?
    GigabitEthernet  GigabitEthernet interface
  
  [XRN]fabric-port gi
  [XRN]fabric-port GigabitEthernet 1/0/27 e
  [XRN]fabric-port GigabitEthernet 1/0/28 e
  

//Note: the lowest unit number is the master//


  [XRN]change self-unit to auto-numbering
  [XRN]quit 
  <XRN>fabric save-unit-id
  save


**Remember the automatic.**


  [5500-EI]change self-unit to auto-numbering


-----


The one that remains below is the master and is the one that closes the back


-----


The master is the one who has the global configuration of the system, it is important that the unit exists for that reason.


-------------

The topology driver is the last of the units usually


  <XRN>dis ftm info
  FTM State       : HB STATE
  Unit ID         : 3 (FTM-Master)

  Advertise ACK   : Send = 0, Receive = 4
  Heart Beat      : Send = 7, Receive = 0
  
  Left Port       : Index = 26, IsEdge = 0
  Right Port      : Index = 27, IsEdge = 0
    
  Units Num Left  : 1
  Units Num Right : 1
  
  Units Num Backup: 1
