I have setup 2 x ASA 5510 in fail over.
Port 0 connects to internet.
Port 1 is trunked to 5 vlans on inside.
fail over link is on port 3.
If i connect the Trunk on the standby asa, the connection to the Primary goes down.
If all cables is connectet at startup i cannot ping any thing, or connect to internet, or to the asa.
if i then disconnects the trunk on standby asa, it all works.
On the seriel cable, all looks normal.. no errors or anything.
I have no idea what could be causing this.
Fw is asa 8.2(1) and asdm 6.2(1)
