[rancid] Ignore differences in certain lines?

[Aaron Wasserott]

Trying to capture 'show interface status' output from Cisco IOS switches, but ignore the output for diff purposes. Is that possible? I guess it would have to be part of the mailer function to not send output for certain lines.

I copied the ShowVLAN sub-routine because it already appends ! in front of the lines, so they are not considered config lines. But right now I can't even get the output captured.

This is the new sub I am using:


# This routine parses "show interface status"
sub ShowIntStat {
    print STDERR "    In ShowIntStat: $_" if ($debug);

    #($_ = <INPUT>, return(1)) if (!$DO_SHOW_INT_STAT);

    while (<INPUT>) {
        tr/\015//d;
        last if (/^$prompt/);
        next if (/^(\s*|\s*$cmd\s*)$/);
        return(1) if /^\s*\^\s*$/;
        return(1) if /Line has invalid autocommand /;
        return(1) if /(Invalid input detected|Type help or )/;
        return(1) if /Ambiguous command/i;
        # newer releases (~12.1(9)) place the vlan config in the normal
        # configuration (write term).
        #return(1) if ($type =~ /^(3550|4500)$/);
        #return(1) if ($type !~ /^(2900XL|3500XL|6000)$/);
        return(-1) if (/command authorization failed/i);
        # the pager can not be disabled per-session on the PIX
        if (/^(<-+ More -+>)/) {
            my($len) = length($1);
            s/^$1\s{$len}//;
        }

        ProcessHistory("COMMENTS","keysort","IO","!INT: $_");
    }
    ProcessHistory("COMMENTS","keysort","IO","!\n");
    return(0);
}
