ACE SIP debug

How to enable SIP debugging in ACE appliance.

We recently implemented an ACE, 1 SIP VIP and 2 remote servers.

We want to see SIP messages processed by ACE appliance.

Thanks!

Justin-

ACE doesn't really have a "debug SIP traffic" command.  It is more obscure commands that would allow you see parts of the loadbalanced conversation.

SIP Inspection Stats:
show np <1 or 2> me-stats "-sappinspect"

Looking at the actual connection:
show conn | i where x.x.x.x is the ip of your client.
Get the NP number from the column and the connection ID, then issue the following:
show np me-stats "-c "'

Debug messages based on the SIP connection:
debug logfile TAC size 10000
debug cfgmgr aisip mask 0x7ffff
debug cfgmgr aitcp mask 0x7ffff
show debug logfile TAC


Sniffer Trace:

Be careful here to limit the ACL to just the traffic you are interested in.  As well, durring the capture, all packets seen will scroll across the screen.
capture TAC-Cap all access-list bufsize 5000 circular-buffer
capture TAC-Cap start
capture TAC-Cap stop
copy capture TAC-Cap disk0: TAC-Cap.cap
copy disk0:TAC-Cap.cap ftp:
