Starting a Local Packet Trace on VNF Systems

You use the start a packet trace by entering the appropriate ACLI command with these pieces of information:

• Network interface (name:subport ID combination)

• (Optional) IP address to be traced; if you do not enter local and/or remote ports when you start the trace, the Oracle® Enterprise Session Border Controller traces all open sockets.

• (Optional) Local UDP/TCP port on which the Oracle® Enterprise Session Border Controller sends and receives traffic to be traced.
• (Optional) Remote UDP/TCP port to which the Oracle® Enterprise Session Border Controller sends traffic, and from which it receives traffic to be traced; you cannot enter the remote port without specifying a local port.
• (Optional) Enter a tcpdump command line within quotes.

Note that the system supports local packet trace on all platforms. To start a packet trace with local and remote ports specified:

1. Enter the ACLI packet-trace local command followed by a Space, and the parameter start. After another space, type in the name and subport ID for the network interface followed by a Space.
   The syntax below includes the IP address to be traced, the local port number, then the remote port number separated by spaces.
2. Press Enter.
