Id is a Byte and specifies the SRclassID in a numeric representation of the SR classes which is supported by a particular Bridge Port (see IEEE 802.1Q-2018, clause 35.2.2.9.2, SRclassID). Only Values between 0 and 7 shall be used.

Priority is a Byte and holds the Data Frame Priority (item a) in IEEE 802.1Q-2018 clause 35.2.2.8.5) value that will be used for streams that belong to the associated SR class. (see IEEE 802.1Q-2018, clause 35.2.2.9.3, SRclassPriority). Only Values between 0 and 7 shall be used.

Vid is an UInt16 and contains the SR_PVID (item i) in IEEE 802.1Q-2018 clause 35.2.1.4) that the associated streams will be tagged with by the Talker (see IEEE 802.1Q-2018, clause 35.2.2.9.4, SRclassVID).
