Andras, We couldn't make ANM 5.2.2 OVF file work at all but I have to admit we didn't spent too much time to get this working. Finally we have used one old ESX 4.x host to import the OVF and moved it then to ESXi 5.1 which runs stable. Since Cisco gives up on ACEs (see related end of sales/end of support notices) I do not expect they will release any newer version of ANM which is supporting more current ESXi versions. I think the signs are inevitable as there was no update since Nov 2012. Best regards, Hans ... View more

Hi Tomasz, You are running into a bug. In release notes for A2(2.x) you see that as open caveats still in version A2(2.2): CSCtb34660—When a client sends large HTTP POST requests, the ACE advertises the incorrect value for the window size when sending the response page. Workaround: Set the buffer share to 64K bytes unless the ACE starts advertising a window size greater than 64K bytes. CSCtb34696—When a large POST request is sent to the ACE VIP address with a default window size, the ACE does not acknowledge the bytes and retransmits them in another frame as a result of a misassignment in a previous GET request. Workaround: Set the buffer share to 64K bytes. You need to configure a connection parameter map an apply it accordingly, which contains the following command: set tcp buffer-share number number is defined from 8192 to 262143 (default value is 32768) I think that will do the trick for you.
