Using SNMP value as index to map for filtering

[greenApples]

I have SNMP table data that looks like this:

Interface index and description:

.1.3.6.1.2.1.2.2.1.1.1 = INTEGER: 1
.1.3.6.1.2.1.2.2.1.1.2 = INTEGER: 2
.1.3.6.1.2.1.2.2.1.1.3 = INTEGER: 3

.1.3.6.1.2.1.2.2.1.2.1 = STRING: "X0 (LAN)"
.1.3.6.1.2.1.2.2.1.2.2 = STRING: "X1 (WAN)"
.1.3.6.1.2.1.2.2.1.2.3 = STRING: "X2 (WAN)"

IP addresses:

.1.3.6.1.2.1.4.20.1.1.10.0.10.1 = IpAddress: 10.0.10.1
.1.3.6.1.2.1.4.20.1.1.100.1.1.1 = IpAddress: 100.1.1.1
.1.3.6.1.2.1.4.20.1.1.150.3.3.3 = IpAddress: 150.3.3.3

IP address interface index:

.1.3.6.1.2.1.4.20.1.2.10.0.10.1 = INTEGER: 1
.1.3.6.1.2.1.4.20.1.2.100.1.1.1 = INTEGER: 2
.1.3.6.1.2.1.4.20.1.2.150.3.3.3 = INTEGER: 3

How can I combine the IP address with the corresponding interface description so I can filter for specific descriptions?
