Type is probably going to be your IF-MIB::ifOctets.526846912<br>
<br>
Do you know how to find the interface index?<br>
$ snmpwalk -v2c -c foo_comm_string foo_host IF-MIB::ifName<br>
IF-MIB::ifName.526846656 = STRING: Ethernet104/1/44<br>
IF-MIB::ifName.526846720 = STRING: Ethernet104/1/45<br>
IF-MIB::ifName.526846784 = STRING: Ethernet104/1/46<br>
IF-MIB::ifName.526846848 = STRING: Ethernet104/1/47<br>
<div>IF-MIB::ifName.526846912 = STRING: Ethernet104/1/48<br>
</div>
(…)<br>
<br>
I imagine you are going to need that. Its probably going to be dropped in to TypeInstance value whole like this<br>
<br>
TypeInstance "IF-MIB::ifName.526846912"<br>
<br>
again, just a guess - this is kinda new to me. I'm adding this back to the mailing list in case anyone else is more familiar.<br>

<div>I haven't tried filtering, but if you only need data for a single interface, then it can be done without the filter; in the 'Data' definition within the snmp plugin config, just specify the OID+index in the 'Values' and set 'Table' to false, which will
lead to only the data for that interface being pulled rather than the plugin parsing the ifTable. Assuming the index of that interface is 12345 on both chassis, something like:</div>

<div>The instance will be appended to the value list, so in this example you'd end up with rrd filenames like 'ifmib_if_octets32-te-0-1', though you may also leave the instance blank.</div>
