Alright, so I'm a little surprised LM doesn't seem to handle this natively, but when a device has a logical interface configured on it and then you delete the logical interface, LM is expecting a response (I think) = 6 which is the component is removed or something along those lines. However, it appears the network appliance community thinks the right answer is this one: No Such Instance currently exists at this OID. I tried this on multiple Juniper routers and on Fortigate and...

What is the discovery schedule? What is the instance auto-deletion set to?
