NETWORK

(Default) Trace messages at the network level. NSTRC records

 

messages at the LI software level as they enter or leave the

 

node. In addition, NSTRC records any Probe, Socket Registry,

 

NFT, TCP, and IP control messages (control messages are

 

messages sent by the protocol modules as part of the protocol

 

and do not contain user data), and HDLC/Multidrop •Link Up"

 

messages. You can use FMTRC to format the IP or LI header

 

(OSI layer 3s--IEEE 802.3/ETHERNET/LAN or

 

Router/1000). FMTRC does not format higherlevel protocol

 

headers, such as TCP or PXP unless the nice format option is

 

used. Useful for analyzing network problems.

SOCKET

Trace messages at the socket level. NSTRC records messages as

 

they are sent and received on user sockets. (You can select

 

messages according to Global Socket Descriptors when you

 

format the trace file via FMTRC.) Useful for debugging user

 

applications.

BOTH

Trace messages at both the network and socket level.

 

Default: NETWORK.

BRTRC Scheduling

[RU,]BRTRC

Caution

If you abort NSTRC instead of terminating it with BRTRC,

 

FMTRC will not be able to format the trace file.

 

 

FMTRC Scheduling

[RU,]FMTRC[,inputDevice][,rawTraceFile][,formattedDevice] [,titleField][,logDevice]

inputDevice

Device (answer file name or interactive device LU) that

 

provides input for FMTRC dialogue.

 

Default: local LU 1 (scheduling terminal).

rawTraceFile

The raw trace file for FMTRC to format. This must be a disk

 

file; if NSTRC posted trace messages to a tape, you must

 

restore the tape's contents to a disk file before formatting it.

 

NSTRC must not have the file open for tracing.

 

Default: NS_TRACE.TRC.

formattedDevice

Device (file name or device LU) to which FMTRC outputs the

 

formatted trace file.

 

Default: If you specified a file for rawTraceFile, FMTRC

 

takes that file name, strips any existing type extension, and adds

 

the type extension FMT to form the name for the formatted

 

(output) file. If you did not specify a rawTraceFile, the

 

default is the file NS_TRACE.FMT.
