This is from some internal PHP thing that isn't very good (well, it's
lovely actually.. the problem is that it uses a forking method to query
everything and isn't that fast. I'm trying to rewrite it)
Throw any of these into google if you're confused about them. It should
return the correct MIB (except for the Casa ones. I'm not sure how I
found those but you can ignore them if you don't have any Casa CMTS)
'.1.3.6.1.2.1.10.127.1.3.3.1.2' => 'macs',
'.1.3.6.1.2.1.10.127.1.3.3.1.3' => 'ips',
'.1.3.6.1.2.1.10.127.1.3.3.1.6' => 'rxpwr',
'.1.3.6.1.2.1.10.127.1.3.3.1.9' => 'status', // genericstatus 0-7
'.1.3.6.1.2.1.10.127.1.3.3.1.13' => 'snr',
'.1.3.6.1.2.1.10.127.1.3.3.1.5' => 'dwnchnl', // this is actually
upchannel ifindex
'.1.3.6.1.2.1.31.1.1.1.1' => 'ifname',
// this is probably for any Cisco Docsis3 CMTS
if ($cmts['DeviceModel']['name'] == 'UBR7225VXR') {
unset($oids['.1.3.6.1.2.1.10.127.1.3.3.1.5']); // remove
dwnchnl, we'll get that from SNR
unset($oids['.1.3.6.1.2.1.10.127.1.3.3.1.13']);
$oids['.1.3.6.1.4.1.4491.2.1.20.1.4.1.4'] = 'snr';
}
switch ($cmts['DeviceType']['name']) {
case 'cisco':
'.1.3.6.1.4.1.9.9.116.1.3.2.1.1' => 'status2', // cisco
specific status cdxCmtsCmStatusValue
'.1.3.6.1.4.1.9.9.114.1.1.5.1.18' => 'flapcount',
'.1.3.6.1.4.1.9.9.114.1.1.5.1.10' => 'flaptime'
break;
case 'Casa':
'.3.6.1.4.1.20858.10.22.2.1.1.1' => 'status3',
// casa specific status (totally different values from cisco)
'.1.3.6.1.4.1.20858.10.11.1.2.1.10' => 'flaptime',
'.1.3.6.1.4.1.20858.10.11.1.2.1.9' => 'flapcount'

things you need to pull from each cable modem:
system.sysUpTime.0
transmission.127.1.1.1.1.6.3 down_pwr
transmission.127.1.2.2.1.3.2 up_pwr
transmission.127.1.1.4.1.5.3 down_snr
You can also pull the modems log via an OID but I don't have that one handy.
