I am looking at my options for dealing with bursty traffic on a trunk link. I am looking at a switched trunk link between a Nexus 9K and a 3560 that has a (now) port channeled interface (bundled two gigabit ethernet links) that currently is dropping an unacceptable amount of outbound packets. I verified that this really is bursty traffic by looking at traffic and buffer statistics, as well as looking at a packet capture.
I significantly lowered the amount of output discards by adding another gigabit interface and making the trunk a port channel. But the output discards are still at an unacceptable level.
The links seem to be able to handle the load, except for the traffic bursts. Do I have any options to remedy this aside from upgrading the links? Can I modify the buffers on the interfaces to accommodate the bursts?

Mostly on the 9K side. I don't see any info on tunable buffers for 9Ks, I don't know if it is possible.
