Using the Trace Option of the TCPIP DEBUG Command

Note: With the exception of the NPDATA, IPDESTADDR, and SECURITY trace options, you must be running the diagnostic version of the software to trace the data path.

Issue the NW TCPIP DEBUG command, using the TRACE option, to trace one or more of the options listed in Trace Options. Note that using any trace option will have some effect on system performance.

Table 6. Trace Options

Trace Options

Action

AC

Traces within Auto-Address Configuration module.

ALL

Traces all of the options described in this table.

ALL MODULES

Traces the following modules: ARP, ATMARP, CIA, DP, ICMP, MSS, PIM, RIP, Security, TCP, TCPM, and UDP.

ARP

Traces within the ARP module.

ARPALL

Traces ARP in both LAN and ATM environments.

ATMARP

Traces ARP in an ATM environment.

BUFFERUTIL

Traces within the buffer utilities.

CIA

Traces within the CIA module (turns on CIADATA, MSSDATA).

DP

Traces routines that handle transferring TCP/IP frames to and from network devices (NPs).

DTCM

Traces within the distributed TCP/IP communications management (DTCM) module. The DTCM module supports the enhanced VLAN performance feature on ClearPath systems.

ICMP

Traces within the ICMP module.

Note: Use the NW TCPIP DISPLAY command to control reporting of ICMP messages

IP

Traces within the IP and MSS modules.

IPDESTADDR <IP address>

Traces the IP header and Upper Layer Protocol (ULP) header information of all packets that are coming from or are being sent to the specified IP address.

Note: Do not use the "NP x" option for this trace. This trace option can only be used in requests applicable to all server environments. Attempting to do otherwise results in a negative response to the request.

IPSEC

Traces within the IPsec module.

The following response is displayed when enabling IPsec tracing: PROCESSED SUCCESSFULLY:TRACE+IPSEC

The following response is displayed when disabling IPsec tracing: PROCESSED SUCCESSFULLY:TRACE-IPSEC

MCPCRYPTO*

Traces all frames that handle SSL MCPCRYPTO operations (see note at end of table).

MSS

Traces within the messaging subsystem (MSS) module. The MSS module supports the enhanced VLAN performance feature on ClearPath systems.

NEIGHBOR

Traces within the Neighbor Discovery module.

NEIGHBORALL

Traces Neighbor Discovery for all environments.

NPDATA

Logs TCP/IP frames to and from network devices (NPs). Turns on CIADATA, MSSDATA.

PIM

Traces within the PIM module.

RIP

Tracing within the RIP module.

SSH*

Traces within the SSH module (see note at end of table).

SECURITY*

Traces within the TCP internal module, including the security logic (see note at end of table).

Note: This option should only be used when instructed by Unisys support personnel.

SOCKETS

Traces within the SOCKETSUPPORT library.

SSL*

Traces within the SSL module (see note at end of table).

SSLHANDSHAKE*

Traces all frames that handle the SSL handshake (see note at end of table).

TCP

Traces with the TCP and DTCM modules.

TCPCONN <connection id>

Traces a specific connection.

TCPM

Traces with the TCPM module.

UDP

Traces with the UDP module.

Note: For the MCPCRYPTO, SSH, SECURITY, SSL, and SSLHANDSHAKE trace options, most of this tracing is written to the securitylog file.
