Looking for troubleshooting suggestions for CSM in Cat6000 ?

I'm looking for some suggestions (show or debug instructions) to troubleshoot connections over the CSM module.

'show ip slb connections' gives

prot vlan source destination state

----------------------------------------------------------------------

In TCP 401 192.16.53.42:3915 159.183.58.196:80 ESTAB

Out TCP 401 159.183.58.201:80 192.16.53.42:3915 ESTAB

However, browser on 192.16.53.42 does not show the page ?

Telnet port 80, from same 192.16.53.42 shows same connection and some http traffic in the telnet session.

Can I see traffic stats, http requests, etc.... on CSM (preferrably sorted by connection) through some show/debug ?

Any other suggestion to debug a connection seen in 'show ip slb conns' ?

Hi Thierry,

when I analized the traffic I used sniffer. It exists some hidden commands, but Cisco does not provide them.

How long you see this message that connection is established. You know that the first CSM established TCP session with requested station, after it tries to make TCP session with server, if everything is OK, it makes transporent connection between station and server. You cou see the message "established" during TCP negotioation. (I had the same result). But after that server did not agree about parameters and sever did not start forwards the interesting traffic. (I could see this only using sniffer).
