IRB is like RVI on Cisco. It's a logical interface, and doesn't have a physical (bandwidth) limitation.
I don't use NMS so can't speak on what you're seeing. But I have 2x 1Gbps interfaces in LACP (ae1) bound to an IRB & 1x 10Gb. show int irb ext shows only 1000 Mbps, but I think that's just a placeholder instead of having different show interface output.
