Why did you nest the subroutine definition? That's very odd to read and will break if you add lexicals. Also, please do not call subroutines using an ampersand. Write err3() rather than &err3(). Anyway..

If I understand your problem description correctly, you want err3() to only be called when none of your lines match? The way you have it, it will be called once for every time a line does not match. Is that what you want it to do? If not, the following would work: 
        my $had_match = 0; #see? now the sub nesting breaks the code..
        while (<TECH>) {
            if ( /$cnip/ ) {
                $had_match++;
                (@npa) = split (/\:/);
                print "\n", " " x 14, "*" x 60;

                print "\n", " " x 24, "=" x 40, "\n";
                print " " x 24, "NPANXX   Line   Switch MSR&CUSTGP VMX
+\n";
                print " " x 24,
                  "$npa[0] $npa[1]  $npa[2]    $npa[3] $npa[4]    $npa
+[5]\n";
                print " " x 24, "=" x 40, "\n\n";
                con();
            }
        }
        close(TECH);    #Close file
        err3($cnip) unless $had_match;
