only messages between the speciﬁed times. The end

time you specify must be later than the start time.

-end

yymmddhhmmss

Exclude messages traced after the speciﬁed date and

time. Use the same format as -start.

You can specify both -start and -end to include

only messages between the speciﬁed times. The end

time you specify must be later than the start time.

Sample Command and Output

The following sample trace command illustrates some of the command

options:

snapfilter -f new.trc -o newout.trc +point APPC,NOF,DLC -lfsid 0a021 +convid

0100000a

This command does the following:

• Takes input from the ﬁle new.trc

• Sends the output to the ﬁle newout.trc

• Includes only APPC, NOF, and DLC messages

• Excludes DLC messages with LFSID 0a021

• Includes only APPC messages with conversation ID 0100000a

The output ﬁle then contains the following:

• All APPC messages with the speciﬁed conversation ID

• All NOF messages

• All DLC messages except those with the speciﬁed LFSID

You can then format this ﬁltered output by using the snaptrcfmt

command, which is explained in the next section.
