I have tried all the options but to no vain, i removed ssh key n generated with ,
768, 1024, etc etc..
Already verified ssh maxsessions 16,
I am trying SSH to admin context. PCAP attached from client nonworking when image uploaded and working after ACE reload,
Client: Source ip: 10.1.29.98, destination IP : 10.1.29.97 ACE vlan20
Actually, during non-working time, only after three way handshake, FIN ACK initiated from ACE and no encryption request is initiated while during working scenario after three way handshake , client three way handshake is initiated and session establish.
If the issue is 100% reproducible, then this could be a bug but i haven't seen anything like reported here. There have been lot of upgrades to A530 in the field. Do you have show tech during the problem along with show logging? I would suggest to open a TAC case with this and collect pcaps as well as show tech along with syslogs during the problem and let them go to development for further analysis if show tech doesn't tell what is going on. That's the proper channel to address the issue.
There was this recent DDTS:
CSCup61227ACE 30 A5(3.0) - Warning:- MTS queue is full opcode 4062sap%d pid %d
I need to see if you are getting the similar message. The SSH seems to fail when this message shows up. If you do sh ssh session-info, do you see any stuck connections? Do you run any script which ssh into ACE periodically to collect data?
