Hi 

I have phisical connection betwen ASA 5510 and routrer 2911 . If I generate some activity in my network , conncection is down, I didnt get any logs in ASDM in ASA and CLI in router , I have " term mon enable" , the only message that I note is increas number of CRC error , If this helps I have IPsec on router over ASA, I check speed, and duplex, I change pachcord many time, reload ASA help only for few hours, I loses connection every few minutes.

Losing connection?? Can you please explain a bit? You are losing P2P connection between ASA and router?

[marcin11988]

yes , I connect via  cable this devices 

[nagasheshu2010]

ok.. how do they connect? Is there any intermediate transport device or something? or is there any transport vendor?

[marcin11988]

no it is directly connection

You said, you do some activity and it goes down? What exactly you are doing?

Can you please also share show interfaces <int> logs for both ends.
