Talking about SIP debugging, there are two options in SN9k:

- To collect a tcpdump, here is an example:

tcpdump -s 0 -i eth2 port 5060 -w /mnt/cdr/sip_trace.pcap ( This command will record a pcap sip sgnalling trace which can be downloaded from the following path: http://192.168.5.5/cdr/ ..... last "/" is mandatory )

- To collect a SIP debug:

Login on the device via the ssh and start the following commands:

showdbg sip on
trace sip start

Once you finish log collecting please stop debugging with a command: trace sip stop
