This is a problem with juniper mx10k routers as they will send its id number on 1.3.6.1.2.1.47.1.1.1.1.13.1 and not the readable model number.
The model number is send by the 1.3.6.1.2.1.1.1.0 oid on those routers and that is last in the current list.
Evaluate if it is possible to change this without breaking all other targets.
Currently we have a list of oids that we scrape to get the model for the model specific oids, and the first one that got data will be the one used.
