Hi,

I do have a setup of a "CRS326-24G-2S+" --> "CRS328-24P-4S+" connected via an MikroTik S+DA0001 DAC showing TX Pauses in SwOS v2.13. Does anyone have any idea what potential issue this relates to and how to fix.

Best Regards

Pause frames are due to Flow Control. You can try turning flow control off, but may experience packet loss (retries) instead.

I am also seeing TX pauses between a 2x10gb LAG between Mikrotik switches (DAC SFP+) but it is intermittent. A few is probably normal with FC enabled.
