I checked it from

 

sh sys connection cs-server-addr 1.1.1.1 cs-server-port 443

 

Also on statistics.....

 

are you using connection mirroring?

 

can you run tcpdump on standby unit and check what packet's destination mac address is?

Hi Nitass,

 

I have same issue and when I checked using the tcpdump on standby unit, I see the destination MAC as the Active device MAC. and yes, the connection mirroring is enabled on all the virtual server.

 

Is it normal behaviour to have the connections including the traffic itself on standby device when connection mirroring is enabled??
