I have 2 rfs7000 in cluster active/standby  and in vrrp since they act as a gateway. Four  AP622's are connected over L2  to the RFS7000.    What is the average time does it take  for the active  RFS to failover to the standby RFS and adopt again the 4 AP's ? On our test, we  have about 90 to 120 seconds downtime during the failover. Is this normal ?  Is there some way to speed it up?
