No link when connecting CCR2216-1G-12XS-2XQ QSPF28 interfaces

Wed Aug 17, 2022 3:13 am

Hi All

We recently purchased a new CCR2216-1G-12XS-2XQ and I am having trouble bring up the link between the device and two of our existing Cisco Nexus 3064-X devices. On the CCR side I am using both the QSFP28 interfaces to connect to the QSFP+ interfaces on the Nexus. I am also using 40G DAC cables from and I specified the encoding for each end of the cable. Before returning the cables I would like to rule out any misconfiguration on my end, which I assume is most likely the case. I am still new to Mikrotik and I was told that to bring the connection up I should only enable one of the interfaces and manually set the speed to 40Gbps but still no luck. Please see some of my configuration below

Good afternoon.

I recently got our 2216 setup and am struggling to get our 100G interfaces to come up as well.
Did you ever get this working?
