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.. -c > On Apr 14, 2016, at 2:28 PM, Craig Baird <cr...@xpressweb.com> wrote: > > I've got a Cisco ME3600X switch connected up to a pair of Cambium PTP820S > radios via gigabit fiber SFPs.
