Hello all,
I'm connecting 2 QSFP LR4 in both QFX3500 and QFX5200. Everything works fine except for when I do the "show interface extensive media" command, I keep seeing queue counter 8 got dropped packets in a 4x10G port configured but not when ports are configured for 1x40G. The "dropped packets" happens in both QFX3500 and QFX5200.

Can someone please explain why it's doing that and how do I prevent it from happening? Thank you in advance!
