ACE Redundancy FT Vlan down

Question

Hi All,
Simple question.
Assuming to have two ACE load balancer installed in two different Catalyst 6500.
The two Catalyst are directly connected over a L2 connection and  all the flow-state information and the redundancy heartbeat information are transmitted over this connection.
One LB is in active and the second one in stand by. The two load balancer processing traffic for the same virtual devices, of course.
Assuming now that the link is in shutdown state.
In this case both ACE LB will be in the Active state.
Could you please briefly describe what are the impact of having two load balancer active at the same time?
Thank you.

Hi Tom,
It looks the vlan and the physical interface are up. You can anyway check the following to confirm:
sh interface gi 1/4
sh interface vlan 12
In "sh interface gi 1/4 counters", do you see the "RX packets" counter increasing?
You should be able to ping 192.168.12.2 from 192.168.12.1 and vice versa. Which ip did you assign to the other peer. Should be:
ft interface vlan 12
  peer ip address 192.168.12.2 255.255.255.0
  ip address 192.168.12.1 255.255.255.0
  no shutdown
You can check as well "sh ft stats" and see if the heartbeats counter are increasing.
Regarding to other interfaces, you mention that you can't ping devices on the ACE adjacent vlans. Are you allowing icmp traffic? For instance:
policy-map type management first-match management
  class management
    permit
class-map type management match-any management
  match protocol icmp any
service-policy input management
Finally, did you check whether you are able to resolve mac addresses?
I hope it helps,
Olivier
