Luke; All l2, no l3. only 4 vlans. 2 peers trunked to a router which trunks back to 2 devices (microwave backhauls).
Chuck; All ports are 10g except the 2 peers are 1g and trunk back to a 10g port for the router wan No TCN's Brian; I have tried a IBM G8124 and a Ubiquiti ES-16-XG both show same exact drops across all ports, makes me think it's a config issue. MTU, FC, something. Andrew; I have tried with FC disabled, but I will try that one more time. Mikael; Is it possible to over run the buffers of a 320gbps backplane switch with only 1.5gbps traffic? I think the switch is rated for 140m PPS and I'm only pushing 100k PPS On Tue, Nov 29, 2016 at 9:47 AM, Mikael Abrahamsson <[email protected]> wrote: > On Tue, 29 Nov 2016, TJ Trout wrote: > > Could this be MTU?
