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.
