Type is probably going to be your IF-MIB::ifOctets.526846912

Do you know how to find the interface index? 
$ snmpwalk -v2c -c foo_comm_string foo_host IF-MIB::ifName
IF-MIB::ifName.526846656 = STRING: Ethernet104/1/44
IF-MIB::ifName.526846720 = STRING: Ethernet104/1/45
IF-MIB::ifName.526846784 = STRING: Ethernet104/1/46
IF-MIB::ifName.526846848 = STRING: Ethernet104/1/47
IF-MIB::ifName.526846912 = STRING: Ethernet104/1/48

I imagine you are going to need that. Its probably going to be dropped in to TypeInstance value whole like this

TypeInstance "IF-MIB::ifName.526846912"

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.
