The above note mentions that the MAC addresses come back converted to integers or something funky like that. Not sure why that is happening but I fixed that with a wrapper function. function PadMAC($mac) { $mac_arr = explode(':',$mac); foreach($mac_arr as $atom) { $atom = trim($atom); $newarr[] = sprintf("%02s",$atom); } $newmac = implode(':',$newarr); return $newmac; } Maybe that will help somebody with that issue. I know I personally use the heck out of these user contributed notes jasper
N.B. it's possible for snmpwalkoid to lose data - the "rmon.matrix.matrixSDTable" table for example uses binary mac addresses as part of the index, these get converted to ascii, and by the time they get to php they can be non-unique - so some entrys in the table get lost...

Looks like timeout is in MICRO seconds. 1,000,000 µs = 1 s |
