hello,
I have HA configuration for two ACE4710. FT between ACE's is configured as L2 (VLAN). Active ACE is sending heartbeats, but switch shows lot of 'input errors' on ingress and this is a major problem. FT is logicaly not working (there is no connection between these two ACE's over VLAN). There is only L2 configuration, with speed and duplex auto, no other special configuration. When I connect ACE's directly, FT is working without problem.
where can be a problem? I can see lot of errors on input direction (from ACE) to switch port, that means, L1, or L2 problem, but direct connection (using the same ethernet cable) is working. I tried 'shut/no shut' on both sides, set duplex/speed,... without success.
ACA IOS version is A4(1.x).

What kind of input errors do you have? Did you configured dot1q on the interface? Did you configured a special VLAN?

Hello Marko,
there were only 'input errors' (no crc, frame, overrun, runts, giants, etc.)
it was not working with this configuration:
ACE side:
interface gigabitEthernet 1/4
ft-port vlan 190
no shutdown
L2 switch side:
interface GigabitEthernet7/47
switchport
switchport access vlan 190
switchport mode access
switchport nonegotiate
no ip address
I'm reading in ACE doc: "When you specify the ft-port vlan command, the ACE modifies the associated Ethernet port or port-channel interface to a trunk port."
that means, L2 switch side should be?
interface GigabitEthernet7/47
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 190
switchport mode trunk
switchport nonegotiate
no ip address

Yep..You are right. You should try this configuration.
