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:

The screen capture shows decoded SOAP transactions.

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).

Note: For more information about the information displayed, see the Request for Comments (RFC) for the protocol being used:

RFC 791 for IP
RFC 793, RFC 1323, and RFC 2018 for TCP
RFC 768 for UDP
RFC 792 for ICMP

The Formatted Packet Display shows several groups of data. Some of these groups of data are displayed in only one format of the panel; others are displayed in two or three of the formats.

Each group of data relates to one of the following:

The packet as a whole
IP
The related protocol (TCP, UDP, or ICMP)

The following table identifies the groups of data displayed in the different formats:

Format	Data Displayed
A	Packet details IP header fields IP options Protocol header fields Protocol data
B	Packet details IP header fields IP options IP header Protocol header fields Protocol header data Protocol data
C	Packet details IP header IP data

Packet Details on the Formatted Packet Display

Packet details are displayed in all three formats of the Formatted Packet Display.

Note: For more information about IP options, see RFC 791.

Protocol Header Fields on the Formatted Packet Display

Protocol header fields are displayed in Format A and Formt B of the Formatted Packet Display. The header displayed depends on the protocol: TCP, UDP, or ICMP.

TCP Header Fields on the Formatted Packet Display
