I'm digging through the admin guide and I cant seem to locate anything about timeouts, other than sticky timeouts...
basically, what i'm looking for is something that will tell me what the "session" timeout setting is...Is it a global setting, is it configured per server farm, etc...???
any help would be appreciated...
Most of the ACE timers can be found at the following link:
Configuring TCP/IP Normalization and IP Reassembly Parameters
Without seeing an actual failure in a network capture, it is hard to speculate on what the cause is. The ACE doesn't care about the size of a file traversing it. If your VIP is only layer 4 (VIP and port), then the ACE sees it as nothing more than a TCP session and doesn't look any higher up the stack. If the class is layer 7 (HTTP header parsing), then it still only looks at the header.
The best place to get a capture is from the ACE tengig port, especially if the client PCs are locked down. The tengig capture will give both sides of the connection. The before and after showtechs will allow you/TAC to see if any error counters are incrementing at the time of a failure.
You can also use the ACE's built-in packet capture utility if all else fails. I like to use a SPAN first. After all, the ACE could be the culprit here, and using the built-in utility is kinda like asking one of the suspects of a crime for the facts of the case. ;- )
Another tool to use is the 'show conn ?' and 'show conn detail' commands immediately after you launch a test connection. This will give you some insight as to the state of the connection and how far along it got.
