Topic: Digiface AVB grandmaster
Hi,
i have a strange problem with my Digiface AVB (firmware v255, driver 4.10).
With some AVB devices in the network (and on the same Presonus SW5E switch), the Digiface is the only device that doesn't select the same Grandmaster as the others, but rather its own PTP clock. The Grandmaster clock is sourced from a Cisco 3150 switch over the Presonus.
Sometime, the Digiface locks to the Grandmaster, then streaming also happens for a short time, but for the most part, it is faulty in this configuration. If it doesn't find the Grandmaster, the AS_PATH data is also empty.
The RME AVB Tool on the same network is stable.
Interestingly, i realized that the two RME devices have quite different PTP settings (communicated over the AVB_INTERFACE descriptor), regarding priorities.

Any clues?
