In the output from the 'show tfo connection summary output' command there are 3 sections :
- Optimized Connection List
- Auto-Discovery Connection List
- Pass-Through Connections
The 'Pass-Through Connections' section is fairly self-evident, but what is the difference between entries in the 'Auto-Discovery Connection List' and the 'Optimized Connection List' sections ?
Also, I have some output that I am having difficulty interpreting :
Auto-Discovery Connection List
E: Established, S: Syn, A: Ack, F: Fin, R: Reset
s: sent, r: received, O: Options, P: Passthrough
Local-IP:Port Remote-IP:Port Conn-Type Orig-St Term-St
10.250.216.5:4050 10.250.195.3:27903 Int. Server SAsO UNU
10.250.195.7:443 10.250.216.5:27655 Ext. Server SAsO SAr
What are do the 'Int. Server' and 'Ext. Server' types mean under the column 'Conn-Type' ?
What are 'Orig-st' and 'Term-st'abbreviations for ? Original state/terminated state ??
Finally, what does the UNU under the Term-st column mean ?
Apologies for the many questions, but I can't find any answers in the Cisco config or command ref guides...
Thanks
Nigel.

Nigel,
The optimized connection list shows connections that are established and being optimized. The auto-discovery connection list shows connections that are still in the auto-discovery phase (i.e. the 3-way setup handshake has not completed).
The designation 'Int. Server' or 'Ext. Server' indicates whether the connection is sourced/destined from/to an internal process (such as WAFS, telnet, etc.) or an external host.
'Orig-st' and 'Term-st' are as you described them.
UNU = unknown.
