[TODO] mactrack_strip_alpha function not working correctly

[edc1]

I've been getting some of our Enterasys switches working with Mactrack and there's a problem with the mactrack_strip_alpha function not removing all alpha characters from the ifType string. The Enterasys switch returns values like this:

rs232(33)
ieee8023adLag(161)

for serial ports and lag ports. mactrack_strip_alpha will return:

rs232(33
ieee8023adLag(161

for these. I've changed the function to this:

function mactrack_strip_alpha($string = "")
{
$matches;
if (preg_match('/^.*\((\d+)\)$/', $string, $matches) == 1)
{
return $matches[1];
}
}

which correctly returns:

33
161

for these ifTypes. This might be useful to someone.

That's a net-snmp configuration change. You are getting the full type, when you should be getting the numerical value only. Which SNMP are you using php-snmp or net-snmp?

I'm using the functions in mactrack_functions.php. I put in lots of print statements to the mactrack_enterasys.php script to help understand it better and it looks like when it retrieves the ifTypes it gets the text value and numerical values. Like this:

rs232(33)

mactrack_strip_alpha just calls trim which doesn't return 33 in this case which I would expect it to do. I think it's because there are digits in the part outside the brackets.

I guess the fix would be to make strip alpha have two methods, one that removes non-numeric data and one that removes everything except what's inside of the brackets.
