Seeking a sanity check regarding switch behavior and mac limits...

What is the expected behavior of a switch that recieves a frame sourced from an unlearned mac when the switch has a mac address limit on the interface, assuming that this limit has not been reached?

My expectation is that this frame will be forwarded, and this certainly is the case with some switches.

However on some Juniper el2s models, the switch drops frames sourced from unlearned macs. Am I crazy in thinking this is unacceptable? In my experience, this breaks shit.
