Using SmartTrace › View a Trace
View a Trace
You can view a packet trace from the following locations:
- From the IP Resource Monitor, IP Node Monitor, or connection list (after activating a trace with the PT command)
- From the Packet Tracing Menu through a list of packet tracing definitions
The trace provides information about the flow of packets and helps you diagnose network problems.
Note: The data displayed depends on your security access. For more information, see your Security Administrator.
The following examples show how traces can help you identify conditions that can contribute to poor response time.
Example: Packet Fragmentation
If a packet is too large and becomes fragmented, it needs to be reassembled at the destination. The process of fragmentation and reassembly can contribute to poor response time.
If a packet has been fragmented, it is indicated under the Summary Information column on the Packet List panel.

Example: Retransmissions
When packets are lost, the lost segment or segments are retransmitted. Retransmissions can contribute to poor response time.
One way that TCP detects packet loss relies on the fact that when an out-of-order segment is received, the receiver generates a duplicate acknowledgement for the highest in-order data byte received. A single duplicate acknowledgement is not a reliable indicator of packet loss because the packets may have been delivered, but not in the original order. TCP distinguishes between these cases by using three duplicate acknowledgements as an indicator of packet loss. When the sending TCP receives the third duplicate acknowledgement, it retransmits the segment referenced by the duplicate ACK number. This is referred to as fast retransmission.
In the following example, the segment with relative sequence number (RelSeq) 1419406 was lost. Packet numbers 1522 through 1524 are duplicate acknowledgements of all data up to the segment with relative sequence number 1419406. Packet number 1524, being the third duplicate acknowledgement, triggers fast retransmission, and packet number 1525 is the retransmission of the segment.

Example: Window Size to Receive Data
Each end of a TCP connection advertises a window size that specifies the size of the buffer that is available to receive data. The size changes as data is moved into or out of the buffer. If the receiver advertises a window size of 0 (a closed window), it stops the data transfer. Closed windows can contribute to poor response time.
When a window is closed, a subsequent TCP segment must be sent to open the window by advertising a nonzero window size.
In the following example, the local end of the connection advertises a window size of 4096 in packet number 0309. After receiving three data packets (0312 through 0314) with a total of 4096 data bytes (excluding the headers), it closes the window with packet number 0315. After a short delay, the local application apparently received 2048 bytes of data, freeing up some local buffer space. The window is reopened with packet number 0317 that advertises a window size of 2048.

Note: If authorized, you can enter the EE command at the Command prompt to view UDP packets as EE packets.
- (Optional) Enter PRINTLIST at the Command prompt to print the packets list.
Locate Packet Data
On a Packet List panel, you can tag packets that contain the data you want to find. You use the TAG command to specify the data you want to locate. The command searches the content of the packets (excluding the IP header) for the specified data. The packets in which the data is located are identified by a TAG flag. You can then use the FIND command to find these flags to locate those packets.
To locate packet data in the listed packets
- Enter TAG.
The TAG Command Prompt panel appears.
- Specify the data you want to locate, and then press F6 (Action).
Packets that contain the specified data are tagged, for example:
0003 192.168.65.11 2859 <- 192.168.65.61 1817 0.001 82 Ack Psh
0004 192.168.65.11 3001 <- 172.24.122.222 4607 0.009 50 Ack Psh
TAG* 192.168.65.11 3001 -> 172.24.122.222 4607 0.009 1492 Ack
TAG2 192.168.65.11 3001 -> 172.24.122.222 4607 <0.001 1456 Ack Psh
0007 192.168.65.11 7005 <- 172.31.9.182 2347 0.147 48 Syn
- Use the FIND command to find the tags:
- TAGn
Indicates that the packet contains the data string specified by the nth tag.
- TAG+
Indicates that the packet contains some of the data strings to be located.
- TAG*
Indicates that the packet contains all the data strings to be located.
To clear selected tags, enter TAGCLR and select the tags to clear.
To clear all tags, enter TAGCLR ALL or press F3 (Exit) to exit the Packet List panel.
Decode Packet Data for Specific Protocols and Ports
Decoding interprets the packet contents according to the specific protocol and application. When a packet is decoded, its data is broken down into individual elements (for example, commands and flags). Whenever possible, the meaning of each element is displayed in readable text. When a packet is not decoded, its data is displayed in hexadecimal dump format with the corresponding EBCDIC and ASCII translations.
TCP packets on the ports specified in the SMARTTRACE parameter group are decoded. The following protocols are decoded:
- Distributed Relational Database Architecture (DRDA)
- FTP
- HTTP
- Simple Object Access Protocol (SOAP) (through HTTP ports)
- Telnet
In addition to this decoding, you can enter the DECODE command on a Packet List panel to decode TCP packet data for other DRDA, FTP, HTTP, and Telnet ports. Decoding applies to the current session. If you exit the panel and then reenter it, enter the command again to perform specific decoding.
Packets that use the following protocols are also decoded by default:
- Enhanced Interior Gateway Routing Protocol (EIGRP)
- Generic Routing Encapsulation (GRE)
- Internet Control Message Protocol (ICMP)
- Internet Group Management Protocol (IGMP)
- IPSec
- Open Shortest Path First Interior Gateway Protocol (OSPFIGP)
- Transport Layer Security (TLS) and Secure Sockets Layer (SSL) handshake
- User Datagram Protocol (UDP) (for Enterprise Extender data only)
Note: Only data packets with header information are decoded. If the data spans multiple packets, only the first packet is decoded.
To decode packet data for other ports
- Enter DECODE.
The DECODE Command Prompt panel appears.
- Specify the port number for the ports you want to decode, and press F6 (Action).
A message appears, indicating that ports are defined for decoding. Part of the decoded information appears under Summary Information.
- Enter S next to a decoded packet to view all the decoded information.
The Formatted Packet Display panel appears, showing the decoded information.
After you specify the decoding of certain ports, you can disable their decoding for the currently listed packets by server port type.
To disable the decoding of user-specified ports for a server type, enter DECODE server_port_type OFF.
Note: For more information about the syntax of the command, see the online help.
Example: Decoding of Packets on Port 21
The following example shows the decoding of Port 21:

DRDA Packets
IBM's DB2 distributed database functionality is based on DRDA. Decoded DRDA packets help application programmers and network analysts who have limited knowledge of DB2 to diagnose problems.
The SMARTTRACE parameter group specifies the ports to decode. You can also use the DECODE command to specify ports on demand.
On the 3270 interface, you can use the following primary commands to change the contents in the Summary Information column:
- SQLVIEW
(Default view) Displays the SQL commands and responses in a DRDA packet. If there is no SQL information, the Distributed Data Management (DDM) commands and responses are shown.
This view is useful for troubleshooting SQL application issues. When a response shows an SQL status code, you can display an explanation of the code using the SQL line command.
- DDMVIEW
Displays only the DDM commands and responses in a DRDA packet. This view requires knowledge of the DRDA command set. The following panel shows the previous example in DDM view:
IPSec Packets
Decoded IPSec packets help network analysts diagnose IPSec problems, for example, error during IKE negotiations.
The following example shows IKE negotiations during the establishment of an Enterprise Extender (EE) connection:
TLS and SSL Handshake Packets
Decoded TLS and SSL handshake packets help network analysts diagnose problems during the negotiations between two applications to establish connection.
The following example shows a typical negotiation:
SOAP Packets
Decoded SOAP packets help network analysts diagnose problems. By reviewing the decoded data, you can easily identify requests that have failed and gain understanding of the data flow that transpires during a web service exchange.
Decoding is limited to HTTP as the underlying protocol for transporting SOAP messages.
The following example shows an error condition:
Typically, SOAP packets are segmented. You can view the reassembled packets using data flow reports.
Hide Decoded Information from the Packet List
During diagnosis, you may want to see the summary information about TCP instead of the decoded FTP, HTTP, and Telnet ports. For example, you may want to find out about the window sizes and sequence numbers across a number of packets. The TCPSUMM command lets you hide any decoded information temporarily on the Packet List panel.
To hide decoded information from the packet list, enter TCPSUMM at the Command prompt.
To redisplay the decoded information, press F6 (Refresh).
View Packet Data
From Packet List, you can view the details of a packet. You can view the details in different formats.
To view the packet data
- Enter V (View) or S beside the packet that you want to view.
The details appear.
Note: To view the actual data in a packet, you must have authority.
- (Optional) Press F6 (Format) to cycle through the formats.
The format of the displayed details changes.
Formatted Packet Display
The contents of the Formatted Packet Display vary according to the type of packet and its contents. There are three display formats for the Formatted Packet Display. You can move between the three display formats by pressing F6 (Format).
