[j-nsp] hold-queue on EX4300 ?

[Saku Ytti]

Hey James,

This isn't specific enough to understand what is going on.

Hold-queue is for punted packets, not particularly important or
interesting usually. So I suspect your issue with JNPR has nothing to
do with your issue in CSCO, two separate matters.

> Or do I'm forced to change buffer size ?

Maybe. Cost optimised platforms have very little delay buffer, because
it's transistor expensive, which is space expensive, which is yield
expensive. If your traffic flows are such that many ports are sending
to one port, or traffic from high speed interface is going to slow
speed interface you definitely need to tune QoS settings but it might
be that you can only improve not fix the situation.
Mind you, you'd need to do this same on 3560 too, and it's not
hold-queue but you'd assign all buffer space into a single queue, to
allow you to sink largest possible microburst.
