The stream gale instance table Contains a set of parameters for each stream gate instance. The parameters for each stream gale instance are as follows:
a) A Stream gale instance identifier. An integer value identifying the stream gate instance.
b) An operational and an administrative strewn gate slate (8.6. 10.4. 8.6.10.5. 1 2.31 .3). A stream gate
can be in one of iwo states:
1) Open: Frames are permitted to pass through the gate.
2) Closed: Frames are not permitted to pass through the gate.
c) An operational and an administrative internal priority value specification (1PV. 8.6.10.6. 8.6.10.7, 12.31.3). An IPV can be citherof the following:
1) The null value. For a frame that passes through the gate. the priority value associated with the frame is used to determine the frame’s traffic class, using the Traffic Class Table as specified in
8.6.6.
2) An internal priority value. For a frame that passes through the gate, the IPV is used, in place of the priority value associated with the frame, to determine the frame’s traffic class, using the Traffic Class Table as specified in 8,6.6.
NOTE I—A use case for the ability to assign internal priority values can be found in IEEE Std 02.lQch ‘ IRl 1.
d) A GaieClosedDueTolnvalidkvEntibk parameter, which takes the value TRUE or FALSE. A value of TRUE indicates that the GateClosedDueTolnvalidRx function is enabled; a value of FALSE indicates that the GateClosedDueTolnvalidRx function is disabled. The default value of GateCloscdDueTolnvalidRxEnahle is FALSE.
e) A GateClosedDueTo!,iwdidkr parameter, which takes the value TRUE or FALSE. If GateClosedDueTolnvalidRxEnable is TRUE, a value of TRUE in GaleClosedDueTolnvalidRx indicates that all frames are dropped (i.e., the gate behaves as if the operational stream gale state is Closed). If GateClosedDucTolnvalidRx is FALSE, il has no effect. The default value of GateClosedDueTolnvalidRx is FALSE; if any frame is discarded because the gate is in the Closed state, then GateClosedDueTolnvalidRx is set TRUE.
NOTE 2—This parameter, in combination with its enable pararneter, allow the detection of incoming frames during time periods when the stream gate is in the closed state to result in the stream gate being pemunently set to a closed state, until such a time as management action is taken to reset the condition. The intent is to support applications where the transmission and reception of frames across the network is coordinated such that frames are received only when the stream gate is open, and hence, a frame received by the stream gate when it is in the closed state represents an invalid receive condition.
1) A GaleClosedDueToOcietsEweededEnable parameter, which takes the value TRUE or FALSE. A value of TRUE indicates that the GateCiosedDucToOctetsExceeded function is enabled: a value of FALSE indicates that the GaieCloscdDucToOctctsExccedcd function is disabled. The default value of GateClosed DucToOcctsExcecdedEnablc is FALSE.
g) A GaieClosedDueToOcteisEvceeded parameter, which takes the value TRUE or FALSE. If GatcCloscdDucToOctctsExcccdcdEnable is TRUE, a value of TRUE in GateClosedDueToOctetsExceeded indicates that all frames are dropped (i.e., the gate behaves as if the operational stream gate state is Closed). If GateClosedDueToOctetsExceeded is FALSE, it has no effect The default value of GateClosedDueToOctetsExceeded is FALSE: if any frame is discarded because there are insufficient lntervalOcietsLeft (8.6.10.8), then GateClosedl)ueToOctetslixceeded is set 1R U E.
h) Optionally. an operational and an administrative stream gale control list. If present. these are ordered lists of stream control operations, as specified in Table 8-7. The state machines that control the execution of the operational stream gate control list, along with their variables and procedures, are specified in 8.6.10.IEEE Std 802.1 Qci  pdf download.
