IEEE Std 802.1Qci-2017 pdf download – Local and metropolitan area networks- Bridges and Bridged Networks- Amendment 28: Per-Stream Filtering and Policing.
NOTE 1- The Maximum SDU size is defined per stream and can therefore differ from the queueMaxSDU specified in 8.6.8.4 of IEEE Std 802.1Qbv. As qucucMaxSDU is applied after the stream filters, it is possible that a frame that passes the Maximum SDU size stream filter will later be discarded because its SDU size exceeds queueMaxSDU. 2) Flow meter instance identifier. The identifier of an instance of a flow metering function as specified in 8.6.5. The flow meter instance is an index into a flow meter instance table (8.6.5.1.3) that specifies the operating parameters for each flow meter instance. Flow metering is always applied after any other filter specifications that could result in frame discard. Frame counters 1) A count of frames matching both the stream handle and priority specifications. 2) A count of frames that passed the stream gate. 3) A count of frames that did not pass the stream gate. 4) A count of frames that passed the Maximum SDU size filter. 5) A count of frames that did not pass the Maximum SDU size filter. 6) A count of frames that were discarded as a result of the operation of the flow meter. g) A StreamBlockedDue ToOversizeFrameEnable parameter, which takes the value TRUE or FALSE. A value of TRUE indicates that the StreamBlockedDueToOversizeFrame function is enabled; a value of FALSE indicates that the StreamBlockedDue ToOversizeFrame function is disabled. The default value of StreamBlockedDueToOversizeFrameEnable is FALSE. h) A SrreamBlockedDue ToOversizeFrame parameter, which takes the value TRUE or FALSE. If StreamBlockedDue ToOversizeFrameEnable is TRUE, a value of TRUE in StreamBlockedDueToOversizeFrame indicates that all frames are to be dropped (i.e., the stream filter behaves as it would if the maximum SDU size were to be set to 0 octets). If StreamBlockedDue’ ToOversizeFrame is FALSE, it has no effect.
