I'll give it a try.  Thanks Cassidy.

Quoting "Cassidy B. Larson" <c...@infowest.com>:

You might want to increase the queue limit on your 1G interfaces.

We do this on our ASR920’s:

class-map match-any cos_all
 match cos  0  1  2  3  4  5  6  7
!
policy-map MC_1G_1M
 class cos_all
  bandwidth percent 100
  queue-limit 1024000 bytes
!
int g0/0/0
 service-policy output MC_1G_1M

Haven’t used M3600X’s before, but it depends on what the buffer size of the total ports are, and probably how many ports are in use as well..

I've got a Cisco ME3600X switch connected up to a pair of Cambium PTP820S radios via gigabit fiber SFPs. I'm seeing significant outdiscards, resulting in lost frames on the switch on both ports going to the 820S radios. The links are not congested--generally pushing less than 100 Mbps (80 MHz channels, capable of 650 Mbps). I've got other 820S radios connected to the same model switch in other places, and am not seeing this. The only difference is that this switch is fed with 10 gig fiber. I'm wondering if it's a queueing problem of some sort. Anybody have any ideas?
