Debugging UDP processes
Syntax: show sip debug udp-process
Debugging SIP packet traces
The show sip debug packet-trace command shows the packets with the IP address of either
src-or-dest-IP-1 or src-or-dest-IP-2. The output displays packet processing starting from parsing to
forwarding. The command is very useful in debugging; however, it only displays in the BP console
not on rconsole.
Syntax: show sip debug packet-trace src-or-dest-IP-1 src-or-dest-IP-2
The following example is a display of "INVITE" packet processing shown on a BP console.
