The output in DR is:

# ipvsadm
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port   Forward Weight ActiveConn InActConn
TCP  192.168.0.11:http wlc
  -> 192.168.0.12:http    Route    1      0          0
  -> 192.168.0.13:http    Route    1      0          0


Whatever I'd try, the  ActiveConn and  InActConn is still 0.
