Manipulating RouterOS data

Manipulating RouterOS data

Getting individual properties

If you try to use shell's "get" command with the API protocol, you'll find it doesn't really work. It returns just a single empty response, as if only to confirm the command's existence.

Getting an individual property is not directly possible with the API protocol, but it can be closely emulated by the use of the "print" command.

A "print" command can take queries, which are described in more detail in a separate tutorial. Combined with the API specific ".proplist" argument (also described in that tutorial), you can make the print command return just one reply, containing just the one property of the one entry that interests you.

For example, if you were interested in getting the MAC address of a certain "arp" entry you've targeted by its IP address:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', 'mac-address');
$printRequest->setQuery(Query::where('address', '192.168.0.100'));
$mac = $client->sendSync($printRequest)->getArgument('mac-address');
//$mac now conains the MAC address for the IP 192.168.0.100
?>

The "numbers" argument

All commands that require you to use the "numbers" argument to target an entry (enable, disable, set, unset and remove), ironically enough, do not accept numbers as their value. Instead, they accept a list of IDs. The IDs you get from API are NOT the same as the numbers you see in the "#" column in shell/Winbox.

There is no way of knowing the IDs without doing a "print" of the targeted entry - from the API protocol - at some point. Ideally, you should do it right when you're about to target the entry. When you do that, the ID is available from an API specific argument called ".id".

Examples

Remove

To delete an entry in the ARP list that has a comment saying "my", we'd do:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', '.id');
$printRequest->setQuery(Query::where('comment', 'my'));
$id = $client->sendSync($printRequest)->getArgument('.id');
//$id now contains the ID of the entry we're targeting

$removeRequest = new Request('/ip/arp/remove');
$removeRequest->setArgument('numbers', $id);
$client->sendSync($removeRequest);
?>

Edit/Set

If we wanted to change the comment of an entry, we would do something like:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', '.id');
$printRequest->setQuery(Query::where('comment', 'my'));
$id = $client->sendSync($printRequest)->getArgument('.id');
//$id now contains the ID of the entry we're targeting

$setRequest = new Request('/ip/arp/set');
$setRequest->setArgument('numbers', $id);
$setRequest->setArgument('comment', 'new comment');
$client->sendSync($setRequest);
?>

Unset

There are some places in RouterOS where it matters whether you have a property with an empty value, or don't have a value for the property at all. In such cases, it is useful to use the "unset" command to remove the property from the entry.

The following example removes the comment from an ARP entry:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', '.id');
$printRequest->setQuery(Query::where('comment', 'my'));
$id = $client->sendSync($printRequest)->getArgument('.id');
//$id now contains the ID of the entry we're targeting

$unsetRequest = new Request('/ip/arp/unset');
$unsetRequest->setArgument('numbers', $id);
$unsetRequest->setArgument('value-name', 'comment');
$client->sendSync($unsetRequest);
?>

Enable/Disable

The following example uses the "disable" command to disable an ARP entry. Analogously, the "enable" command would enable an entry:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', '.id');
$printRequest->setQuery(Query::where('comment', 'my'));
$id = $client->sendSync($printRequest)->getArgument('.id');
//$id now contains the ID of the entry we're targeting

$disableRequest = new Request('/ip/arp/disable');
$disableRequest->setArgument('numbers', $id);
$client->sendSync($disableRequest);
?>

Note: It's a list

Keep in mind the "numbers" argument accepts a list - a comma separated list to be exact. So if you need to, you can have several IDs lined up, like if you had multiple ARP entries for a MAC address, you can remove them all at once with something like the following:

<?php
namespace PEAR2\Net\RouterOS;
require_once 'PEAR2/Net/RouterOS/Autoload.php';
 
$client = new Client('192.168.0.1', 'admin');

$printRequest = new Request('/ip/arp/print');
$printRequest->setArgument('.proplist', '.id');
$printRequest->setQuery(Query::where('mac-address', '00:00:00:00:00:01'));

$idList = array();
foreach ($client->sendSync($printRequest)->getAllOfType(Response::TYPE_DATA) as $entry) {
    $idList[] = $entry->getArgument('.id');
}
//$idList now contains an array of all targeted entries' IDs.

$removeRequest = new Request('/ip/arp/remove');
$removeRequest->setArgument('numbers', implode(',', $idList));
$client->sendSync($removeRequest);
?>
